Instant Wireless™ Series
Introduction
Thank you for choosing the Instant Wireless™ Wireless Access Point Router. This
Router will allow you to set up a network with your PCs and even share your
Internet connection.
How does the Router do all of this? By connecting your cable or DSL modem
directly to the Router and using the Router's Ethernet ports to connect your PCs,
it's almost as if each PC is connected directly to the Internet. In this way, you can
have several PCs utilizing one Internet connection simultaneously. Plus, because
it's also an Access Point, the Router can bridge your Ethernet network with your
wireless PCs.
Wireless Access Point Router with 4-Port Switch
Use the instructions in this Fast Start to help you connect the Router, configure your
PCs, and configure the Router in your network. These instructions should be all you
need to get you up and running with a basic network, sharing your Internet access.
The Router also comes equipped with more advanced functions, but these functions
should not be utilized without a further understanding of routers and networks.
These and other issues are explained in the User Guide on the Setup Wizard CD-ROM.
This is What You Will Be Setting Up
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one
printer from different computers and access data located on another computer's
hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun.
The PCs you connect to the Router's four LAN ports, when properly configured,
create a LAN, or Local Area Network. They are connected with an Ethernet cable
plugged into your computer's Ethernet adapter at one end and into one of the
Router's LAN ports (numbered from one to four) at the other end. The term
"Ethernet" is used to refer to your network accessories, such as cables and
adapters, because Ethernet refers to the type of network you are setting up. In your
Router's documentation, Ethernet refers to accessories that transfer computer
data from 10Mbps to 100Mbps. (10Mbps and 100Mbps refer to the speeds used
by network devices. When transferring data at 10Mbps, you are moving the equivalent of over seven floppy disks every second! Network accessories that function
at 100Mbps move data ten times faster!)
The Router’s setup is similar to that shown in the figure above for any Windows PC.
The Router lets you share your cable or DSL connection among several computers
in your home or business. This is called a Local Area Network or LAN.
PCs can also interact with the Router wirelessly. By configuring your wireless PCs
with the same wireless settings as the Router, you can bridge these wireless PCs
while integrating them into your existing Ethernet network.
Step 2: Configure the PCs
Perhaps the most remarkable thing the Router does is to allow you to share your
cable or DSL connection. This is done by connecting your cable or DSL modem to
the Router's WAN port with an Ethernet cable. (WAN refers to a Wide Area
Network.) The Internet is a network that, being global, covers the widest area of
all! The PCs connected to the Router share this connection.
This Fast Start guide gives you the “big picture” of what you need to set up a basic
home or business network. The next three sections explain how you will set up and
configure your equipment to enable shared high-speed access to the Internet.
Step 1: Connect the Router
This walks you through the process of connecting the Router to your cable or DSL
modem. Then, it shows you how your PCs are connected to the Router.
This describes how your PCs are configured to communicate with the Router.
Step 3: Configure the Router
This step walks you through some basic Router settings, making it work with your
cable or DSL modem and your ISP’s settings.
Note: This Fast Start Guide will direct you how to set up the Router with
Ethernet cables. While the Router can be set up through a wireless connection, details about setting up the Router wirelessly will not be addressed in
this Fast Start Guide. Those who wish to set up the Router through their wireless connection should refer to the Linksys website at www.linksys.com.

Step 1: Connect the Router
Wireless Access Point Router with 4-Port Switch
B. Using an Ethernet cable, connect the
LAN or Ethernet port of the cable or DSL
modem to the Router’s WAN port.
In Step 1, you will connect the Router to your cable or DSL modem and to your
home or business computers.
First, make sure that all devices you’ll be working with are powered down, including your PCs, modem, and the Router.
A. If you haven’t already done so, connect your cable or DSL modem to its proper connection—the coaxial jack for cable (Figure A1), or the phone jack for DSL
(Figure A2). (Follow the instructions from your cable or DSL modem’s installation guide.)
C. Connect an Ethernet cable to
your PC’s Ethernet adapter.
Connect the other end of the
cable to one of the Router’s
LAN ports. Repeat this
process for every PC you wish
to connect to the Router.
C1
Note: If your PC’s Ethernet adapter is not set up, please refer to the Ethernet
adapter’s documentation for more information.
For ease of installation, start with LAN
Port 1 on the Router, then Port 2, Port 3,
and finally Port 4.
If you are connecting more than four
PCs to the Router, you will need to connect a hub or switch to the Router’s
Uplink port (if you use the Uplink port,
then you cannot use Port 4). For information on Uplinking, please refer to the
User Guide located on the Setup Wizard
CD-ROM.
C2
D. Connect the power adapter to the Router’s Power port. Then, connect the
power adapter to an electrical outlet. Turn on the cable or DSL modem. Then
turn on the first PC you wish to use when configuring the Router.

Step 2: Configure the PCs
Wireless Access Point Router with 4-Port Switch
If you are running:
Windows 95, Windows 98, Windows Me
A. Click the Start button, click Settings and
open the Control Panel. From there, double-click the Network icon to open the
Network screen.
In Step 2, you will configure each of your computers to communicate with the
Router.
To do this, you will need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically. Computers use IP addresses to communicate with
each other across a network or the Internet.
Find out which operating system your computer is running, such as Windows 95,
98, Millennium, 2000, or XP. You will need to know which operating system your
computer is running. You can find out by clicking the Start button and then selecting the Settings option. (If your Start menu doesn’t have a Settings option, you’re
running Windows XP. You can select the Control Panel directly from the Start
Menu.) Then, click Control Panel and double-click the System icon. Click the
Cancel button when done.
Once you know which Windows operating system you are running, follow the
directions in this step for your computer’s operating system. You may need to do
this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your TCP/IP settings
based on the type of Windows operating system you are using. Once you've configured your computers, continue to Step 3: Configure the Router.
B. Select the Configuration tab and highlight
the TCP/IP line for the applicable
Ethernet adapter*. If the word TCP/IP
appears by itself, select that line**. Then,
click the Properties button.
C. Click the IP Address tab and select
Obtain an IP address automatically.
D. Click the Gateway tab and verify that the
Installed Gateway field is blank. Click the
OK button.
E. Click the OK button again. Windows may
ask you for the original Windows installation disk or additional files. Supply them
by pointing to the correct file location, e.g.,
D:\win98, D:\win9x, c:\windows\options\cabs, etc. (This assumes that “D” is
the letter of your CD-ROM drive).
F. If Windows asks you to restart your PC, click the Yes button. If Windows does
not ask you to restart, restart your computer anyway.
*Note: Do not choose a TCP/IP entry whose name mentions DUN, PPPoE, VPN, or
AOL.
**Note: If there is no TCP/IP line listed, refer to the User Guide found on the Setup
Wizard CD-ROM or your Ethernet adapter’s documentation to install TCP/IP
now.

For example, the following are typical LEDs that light up once a computer and
a cable or DSL modem are connected:
When the Router is turned on (the power adapter is plugged into the
Router), the Power LED lights up.
When an Ethernet cable is properly connected between a PC and Port 4 of
the Router, the Link/Act, Ful/Col, and 100 LEDs in Column 4 light up.
A cable or DSL modem connection causes the WAN Link LED to light up.

• My WAN Link LED isn’t lit. What should I check?
Check that the cable you are using between your cable or DSL modem
and the Router is the same cable that came with your modem. Depending
on the type of connection your modem uses, you may need either a
“straight-through” or “crossover” Ethernet cable (the “straight-through”
type is more common).
• Some of the lights on the front of the Router don’t light up when I plug in a PC.
•
C. Now you will configure some settings in Windows.
Only the Link/Act LED is required for a connection to work correctly.
3. I cannot get onto the Internet, nor can I access the Router’s Setup page.
What should I check?
A. First check that the cable or DSL modem and computers are properly connected to the Router. See Question #2 for how to verify that the connections
are good.
B. Then, check that you have properly configured your PCs to communicate with
the Router. Below you will find instructions for the various versions of
Windows.

Configuring Wireless Security
Note: WEP encryption is an additional data security measure and not essential for router operation.
6. I get no signal strength or link quality or signal strength, what can I do?
A. Verify that the Router’s WLAN LED is illuminated.
B. Verify that all of your wireless PCs are using “Infrastructure” mode.
7. How can I improve the Router’s range?
A. Verify that the Router is as high off of the ground as possible.
B. Verify that there are no large sources of electrical interference nearby. (For
example: speakers breaker boxes, florescent lights, microwaves, etc.)
C. Change the wireless channel being used. To do this:
Open your web browser and type http://192.168.1.1 into the "Address" field.
In the "Enter Network Password" box, leave the "User Name" field blank and
type admin as the password. Then, click OK.
From the Setup tab, change the channel to 1.
Click the Apply button to save the settings.
Continue doing this until you find the channel that provides the best range.
An acronym for Wired Equivalent Privacy, WEP is an encryption method used
to protect your wireless data communications. WEP uses a combination of 64bit or 128-bit keys to provide access control to your network and encryption
security for every data transmission. To decode a data transmission, each point
in a network must use an identical 64-bit or 128-bit key. Higher encryption levels mean higher levels of security, but due to the complexity of the encryption,
they may mean decreased network performance.
You may also have heard the term “40-bit” used in conjunction with WEP
encryption. This is simply another term for 64-bit WEP encryption. This level
of WEP encryption has been called 40-bit because it uses a 40-bit secret key
along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may
use either name. Linksys uses the term “64-bit” when referring to this level of
encryption.
Make sure your wireless network is functioning before attempting to configure
WEP encryption.
A 128-bit WEP encrypted wireless network will NOT communicate with a 64bit WEP encrypted wireless network. Therefore, make sure that all of your
wireless devices are using the same encryption level. All wireless devices complying with the 802.11b standard will support 64-bit WEP.
In addition to enabling WEP, Linksys also recommends the following security
implementations:
• Changing the SSID from the default “linksys”
• Changing the WEP key regularly
Note: In order for WEP Encryption to be enabled, wireless functions must first
be enabled. Select Enable on the Router’s Wireless tab before proceeding.

The following steps will show you how to utilize WEP encryption
1. From the Web-based Utility’s Setup tab, select Mandatory under the WEP
section.
2. Press the WEP Key Setting button to set the WEP Encryption type and
level.
Wireless Access Point Router with 4-Port Switch
•
WEP (64Bit or 128B) Select the level of encryption from the drop-down
box. 128-bit WEP encryption is unique to Linksys and may conflict with
other vendors’ WEP encryption.
Note: In order to utilize WEP encryption, all points in your wireless
network must have WEP enabled and be set to the same Key Setting.
The WEP Encryption key is generated in one of two ways:
3. The screen displayed in Figure
C-1 may appear,
verifying that you
are enabling WEP
Encryption. Press
the OK button to
continue.
1. You may create an encryption key by using a Passphrase.
a. Enter a Passphrase, a user-defined password, into the Passphrase field.
The Passphrase can be a maximum of 31 letters, symbols, and numbers.
No spaces can be used.
Figure C-1
4. This will display the screen shown in Figure C-2. From this screen, you will
choose your WEP Encryption settings.
b. Click the Generate button to create a key. The key will be 10 digits if
you chose 64-bit encryption, or 26 digits if you chose 128-bit encryption.
This key will be used to encrypt and decrypt the data being sent between
the Router and your network’s wireless PCs.
The Key field may not display all digits. Using the mouse, click anywhere within the Key field. Move the cursor to the right to view the rest
of the Key. Make sure your write down the entire Key EXACTLY the
way it is displayed.
2. You may enter the encryption key manually.
Make a note of the Passphrase or Manual Key. You will need it for the other
wireless devices on the network, as the same WEP encryption key must be
entered in all wireless devices on the network.
Once you have chosen your key encryption method and entered either the
Passphrase or manual key, click the Apply button, and the encryption portion
of the setup is complete.
Note: In Windows XP, a 128-bit Key generated by the Router
will be called a "104 bits (26 digits)" key, and a 64-bit Key generated by the Router will be called a “40 bits (10 digits)” key.

Instant Wireless™ Series
Introduction
Merci d’avoir choisi le routeur de point d’accès sans fil Instant Wireless™. Ce routeur permet de relier des PC en réseau et même de partager une connexion Internet.
Comment le routeur procède-t-il ? En connectant votre modem câble ou DSL directement au
routeur et en utilisant les ports Ethernet du routeur pour relier vos PC, c’est un peu comme
si chaque PC était directement connecté à Internet. Plusieurs PC peuvent ainsi utiliser
simultanément une même connexion Internet. Le routeur constituant également un point
d’accès, il peut établir un pont entre votre réseau Ethernet et vos PC sans fil.
Routeur de point d’accès sans fil avec commutateur 4 ports
Utilisez les instructions de ce Guide de démarrage rapide pour connecter le routeur, configurer
vos PC et configurer le routeur sur votre réseau. Ces instructions contiennent toutes les informations nécessaires à la mise en service d’un réseau de base avec partage de votre accès à
Internet. Le routeur est également équipé de fonctions plus avancées, mais elles ne doivent
pas être utilisées sans une connaissance approfondie des routeurs et des réseaux. Celles-ci,
ainsi que d’autres sujets, sont abordés dans le Guide de l’utilisateur figurant sur le CD-ROM
Setup Wizard (Assistant Installation).
Vue d’ensemble de l’installation
Possibilités offertes
Les réseaux constituent de puissants outils pour partager des ressources informatiques.
Vous pouvez utiliser une imprimante depuis différents ordinateurs et accéder aux données
résidant sur le disque dur d’un autre ordinateur. Les réseaux permettent également d’utiliser à plusieurs des jeux vidéo. Les réseaux sont donc non seulement très utiles, mais peuvent
également s’avérer ludiques.
Les PC que vous connectez aux quatre ports de réseau local du routeur, s’ils sont correctement configurés, créent un réseau local. Ils sont connectés au moyen d’un câble Ethernet
branché à une extrémité sur l’adaptateur Ethernet de l’ordinateur et sur les ports de réseau
local du routeur (numérotés de 1 à 4) à l’autre extrémité. Le terme « Ethernet » fait
référence aux accessoires de réseau, tels que câbles et adaptateurs, et désigne le type de
réseau mis en place. Dans la documentation du routeur, Ethernet fait référence aux accessoires qui transfèrent les données informatiques à un débit compris entre 10 Mbits/s et
100 Mbits/s. 10 Mbits/s et 100 Mbits/s désignent les vitesses utilisées par les périphériques
réseau. Lors d’un transfert de données à 10 Mbits/s, vous transférez l’équivalent de plus de
sept disquettes par seconde ! Les accessoires réseau qui fonctionnent à 100 Mbits/s offrent
des débits dix fois plus rapides !
La configuration du routeur est similaire à celle illustrée à la figure ci-dessus pour tout PC
Windows. Le routeur vous permet de partager votre connexion DSL ou par câble entre
plusieurs ordinateurs à domicile ou au bureau. Cela s’appelle un réseau local ou LAN.
Ce Guide de démarrage rapide vous donne un « aperçu général » de ce dont vous avez besoin
pour configurer un réseau de base chez vous ou au bureau. Les trois prochaines sections
expliquent comment installer et configurer votre équipement pour permettre un accès partagé
et grande vitesse à Internet.
Les PC peuvent également être raccordés au routeur par une connexion sans fil. En configurant les PC sans fil avec les mêmes paramètres sans fil que le routeur, vous pouvez raccorder ces PC tout en les intégrant à votre réseau Ethernet existant.
Étape 1 : connexion du routeur
Mais le routeur permet surtout de partager votre connexion câble ou DSL. Pour cela, il suffit de connecter votre modem câble ou DSL au port WAN du routeur avec un câble Ethernet.
Le terme WAN (Wide Area Network) désigne un réseau étendu. Internet est un réseau global couvrant la zone la plus vaste qui soit ! Les PC connectés au routeur partagent cette
connexion.
Étape 2 : configuration des PC
Cette étape vous guide à travers la procédure de connexion du routeur à votre modem câble
ou DSL. Elle explique ensuite comment connecter vos PC au routeur.
Cette étape indique comment configurer vos PC pour communiquer avec le routeur.
Étape 3 : configuration du routeur
Cette étape décrit certains paramètres de base du routeur qui lui permettent de fonctionner
avec votre modem câble ou DSL de même qu’avec les paramètres de votre ISP.
Remarque : ce Guide de démarrage rapide décrit l’installation du routeur avec des
câbles Ethernet. Bien que le routeur puisse être installé au moyen d’une connexion sans
fil, cette configuration n’est pas décrite dans ce Guide de démarrage rapide. Si vous
souhaitez installer le routeur en employant une connexion sans fil, reportez-vous aux
informations présentées sur le site Web Linksys à l’adresse www.linksys.com.

B. À l’aide d’un câble Ethernet, raccordez le
port Ethernet du modem câble ou DSL au
port WAN du routeur.
À l’étape1, vous allez connecter le routeur à votre modem câble ou DSL, ainsi qu’aux ordinateurs de votre domicile ou bureau.
Vérifiez d’abord que tous les appareils que vous utiliserez sont hors tension, notamment les
PC, le modem et le routeur.
A. Si ce n’est déjà fait, branchez votre modem câble ou DSL sur la prise adéquate : la prise
coaxiale pour câble (figure A1) ou la prise téléphonique pour DSL (figure A2). (Suivez les
instructions du Guide d’installation de votre modem câble ou DSL.)
C. Branchez un câble Ethernet sur
l’adaptateur Ethernet du PC.
Branchez l’autre extrémité du
câble sur l’un des ports de réseau
local du routeur. Recommencez
cette opération pour chaque PC à
connecter au routeur.
C1
Remarque : si l’adaptateur Ethernet du PC n’est pas installé, reportez-vous à sa documentation pour plus d’informations.
Pour simplifier l’installation, commencez par
le port de réseau local 1 sur le routeur, puis le
port 2, le port 3 et enfin le port 4.
Si vous connectez plus de quatre PC au routeur, vous devrez connecter un hub ou un
commutateur au port de liaison montante
(Uplink) du routeur (si vous utilisez le port de
liaison montante, vous ne pouvez pas utiliser le port 4). Pour plus d’informations sur
les liaisons montantes, reportez-vous au
Guide de l’utilisateur figurant sur le CD-ROM
Setup Wizard (Assistant Installation).
C2
D. Branchez l’adaptateur de courant sur le port d’alimentation du routeur, puis sur une
prise électrique. Mettez le modem câble ou DSL sous tension. Mettez ensuite sous tension le premier PC à utiliser lors de la configuration du routeur.
Passez à l’étape 2 : configuration des PC (page suivante).

A.
À l’étape 2, vous allez configurer chacun de vos ordinateurs pour communiquer avec le routeur.
Pour cela, vous devrez configurer les paramètres réseau du PC afin d’obtenir automatiquement une adresse IP (ou TCP/IP). Les ordinateurs emploient des adresses IP pour communiquer entre eux sur un réseau ou sur Internet.
Identifiez le système d’exploitation utilisé sur votre ordinateur, par exemple Windows 95, 98,
Millennium, 2000 ou XP. Vous devez savoir sous quel système d’exploitation votre ordinateur fonctionne. Pour cela, cliquez sur le bouton Démarrer, puis sélectionnez l’option
Paramètres. (Si le menu Démarrer ne comporte pas d’option Paramètres, vous utilisez
Windows XP. Vous pouvez accéder directement au Panneau de configuration depuis le menu
Démarrer.) Cliquez ensuite sur Panneau de configuration, puis double-cliquez sur l’icône
Système. Cliquez sur le bouton Annuler une fois que vous avez terminé.
Une fois que vous connaissez le système d’exploitation Windows utilisé, suivez les directives de cette étape correspondant au système d’exploitation de l’ordinateur. Vous devrez
éventuellement suivre cette procédure pour chaque ordinateur à connecter au routeur.
Les pages suivantes présentent la procédure pas à pas de configuration des paramètres
TCP/IP en fonction du type de système d’exploitation Windows employé. Une fois les ordinateurs configurés, passez à l’étape 3 : configuration du routeur.
Dans le menu Démarrer, choisissez
Paramètres et ouvrez le Panneau de configuration. Dans le Panneau de configuration,
double-cliquez sur l’icône Réseau pour ouvrir
l’écran Réseau.
B. Sélectionnez l’onglet Configuration et mettez
en surbrillance la ligne TCP/IP de l’adaptateur
Ethernet concerné*. Si le mot TCP/IP apparaît
seul, sélectionnez cette ligne**. Cliquez ensuite
sur le bouton Propriétés.
C. Cliquez sur l’onglet Adresse IP et sélectionnez
Obtenir une adresse IP automatiquement.
D. Cliquez sur l’onglet Passerelle et vérifiez que
le champ Passerelles installées est vide.
Cliquez ensuite sur le bouton OK.
E. Cliquez de nouveau sur le bouton OK. Windows
peut vous demander la disquette d’installation
Windows d’origine ou des fichiers supplémentaires. Indiquez leur emplacement, par exemple
D:\win98, D:\win9x, c:\windows\options\cabs,
etc. Cela suppose que « D » soit la lettre du
lecteur de CD-ROM.
F. Si Windows vous demande de redémarrer le PC, cliquez sur le bouton Oui. Même si
Windows ne vous le demande pas, redémarrez quand même l’ordinateur.
*Remarque : ne choisissez pas une entrée TCP/IP dont le nom contient le terme DUN, PPPoE,
VPN ou AOL.

Routeur de point d’accès sans fil avec commutateur 4 ports
Configuration de la sécurité sans fil
Remarque : le cryptage WEP est une mesure de
sécurité des données supplémentaire, non essentielle au fonctionnement du routeur.
WEP (Wired Equivalent Privacy) est une méthode de cryptage employée pour protéger
vos communications sans fil. WEP utilise une combinaison de clés 64 bits ou 128 bits
pour mettre en œuvre un contrôle d’accès à votre réseau et des fonctions de sécurité par
cryptage pour chaque transmission de données. Pour décoder une transmission de données, chaque point du réseau doit utiliser une clé 64 bits ou 128 bits identique. Des
niveaux de cryptage élevés augmentent le niveau de sécurité, mais, en raison de leur
complexité, peuvent entraîner une diminution des performances du réseau.
Le terme « 40 bits » désigne parfois le cryptage WEP. Il correspond simplement au
cryptage WEP 64 bits. Ce niveau de cryptage WEP est qualifié de cryptage 40 bits
parce qu’il utilise une clé secrète 40 bits avec un vecteur d’initialisation 24 bits (40 + 24
= 64). Les fournisseurs sans fil utilisent indifféremment ces deux noms. Linksys utilise
le terme « 64 bits » pour désigner ce niveau de cryptage.
Vérifiez le fonctionnement de votre réseau sans fil avant de tenter de configurer le
cryptage WEP.
Un réseau sans fil à cryptage WEP 128 bits NE PEUT PAS communiquer avec un
réseau sans fil à cryptage WEP 64 bits. Par conséquent, vérifiez que tous vos dispositifs sans fil utilisent le même niveau de cryptage. Tous les dispositifs sans fil conformes à la norme 802.11b prennent en charge le cryptage WEP 64 bits.
Outre l’activation du cryptage WEP, Linksys recommande également la mise en œuvre
des mesures de sécurité suivantes :
• Changement du SSID par défaut « linksys »
• Changement régulier de la clé WEP
Remarque : pour activer le cryptage WEP, vous devez d’abord activer les fonctions sans fil. Sélectionnez Enable (Activer) dans l’onglet Wireless (Sans fil)
du routeur avant de continuer.

La procédure suivante indique comment utiliser le cryptage WEP
1. Dans l’onglet Setup (Configuration) de l’utilitaire Web, sélectionnez Mandatory
(Obligatoire) dans la section WEP.
2. Cliquez sur le bouton WEP Key Setting (Paramètre de clé WEP) pour définir le
type et le niveau de cryptage WEP.
3. L’écran affiché à la
figure C-1 peut
apparaître pour vérifier que vous activez
le cryptage WEP.
Cliquez sur le bouton OK pour continuer.
Routeur de point d’accès sans fil avec commutateur 4 ports
•
WEP (64 Bit or 128 B) (WEP 64 bits ou 128 bits) Sélectionnez le niveau de cryptage
dans la zone de liste déroulante. Le cryptage WEP 128bits est propre à Linksys et
peut créer des conflits avec le cryptage WEP d’autres fournisseurs.
Remarque : pour utiliser le cryptage WEP, tous les points du réseau
sans fil doivent activer le cryptage WEP et être configurés avec les
mêmes paramètres de clé.
La clé de cryptage WEP est générée de l’une des deux manières suivantes :
1. Vous pouvez créer une clé de cryptage en utilisant une phrase de passe
(Passphrase).
Figure C-1
4. L’écran présenté à la figure C-2 apparaît. Vous pouvez y choisir les paramètres de
cryptage WEP.
a. Renseignez le champ Passphrase (mot de passe défini par l’utilisateur). Cette
phrase peut comporter jusqu’à 31 lettres, symboles et chiffres. Les espaces sont
interdits.
b. Cliquez sur le bouton Generate (Générer) pour créer une clé. La clé comportera
10 chiffres si vous choisissez un cryptage 64 bits ou 26 chiffres si vous choisissez un cryptage 128 bits. Cette clé sera utilisée pour crypter et décrypter les données échangées entre le routeur et les PC sans fil de votre réseau.
Le champ Key (Clé) n’affiche pas nécessairement tous les chiffres. Cliquez dans
le champ Key (Clé). Déplacez le curseur vers la droite pour afficher le reste de
la clé. Notez toute la clé EXACTEMENT telle qu’elle apparaît.
2. Vous pouvez entrer la clé de cryptage manuellement.
Notez la phrase de passe ou la clé manuelle. Vous aurez besoin de ces informations pour
les autres dispositifs sans fil sur le réseau, puisque la même clé de cryptage WEP doit
être entrée sur tous les périphériques sans fil sur le réseau.
Une fois que vous avez choisi la méthode de cryptage de clé et entré la phrase de passe
ou la clé manuelle, cliquez sur le bouton Apply (Appliquer) pour mettre fin à la partie
cryptage de la configuration.
Remarque : dans Windows XP, une clé 128 bits générée par le
routeur sera qualifiée de clé « 104 bits (26 chiffres) » et une clé
64 bits générée par le routeur de clé « 40 bits (10 chiffres) ».

Instant Wireless™-Serie
Einführung
Vielen Dank für die Wahl des Instant Wireless™ Wireless Access Point-Routers. Dieser
Router ermöglicht Ihnen die Einrichtung eines Netzwerks mit Ihren PCs sowie die Freigabe
Ihrer Internet-Verbindung im Netzwerk.
Wie kann der Router diese Funktionen erfüllen? Wenn Sie Ihr Kabel- oder DSL-Modem
direkt mit dem Router verbinden und Ihre PCs an den Ethernet-Ports des Routers
anschließen, ist die Wirkung dieselbe, als wäre jeder PC direkt mit dem Internet verbunden.
Auf diese Weise können mehrere PCs gleichzeitig eine Internet-Verbindung verwenden. Da
der Router zugleich ein Access Point ist, kann er Ihr Ethernet-Netzwerk mit Ihren kabellosen
PCs als Bridge verbinden.
Wireless Access Point-Router mit 4-Port-Switch
Die Anweisungen in dieser Kurzanleitung helfen Ihnen, den Router anzuschließen, Ihre PCs zu
konfigurieren und den Router in Ihrem Netzwerk einzurichten. Diese Anweisungen sollten
ausreichen, um ein einfaches Netzwerk mit freigegebenem Internetzugriff in Betrieb zu
nehmen. Der Router verfügt auch über erweiterte Funktionen, die jedoch ein entsprechendes
Fachwissen über Router und Netzwerke voraussetzen. Diese und andere Themen werden im
Benutzerhandbuch behandelt, das sich auf der CD des Setup-Assistenten befindet.
So sieht die fertig gestellte Struktur aus:
Was bedeutet das?
Netzwerke sind ein wirkungsvolles Mittel zur gemeinsamen Nutzung von
Computerressourcen. Über Netzwerke können Sie beispielsweise von verschiedenen
Computern aus auf einen Drucker zugreifen und mit Daten arbeiten, die sich auf der
Festplatte eines anderen Computers befinden. Netzwerke werden sogar dazu verwendet,
Videospiele mit mehreren Spielern zu ermöglichen. Sie sind also nicht nur für die Arbeit
zuhause und im Büro, sondern auch für die Freizeit nützlich.
Die PCs, die Sie an die vier LAN-Ports des Routers anschließen, bilden bei richtiger
Konfiguration ein so genanntes LAN (Local Area Network), d. h. ein Nahbereichsnetzwerk.
Sie sind über Ethernet-Kabel verbunden, die jeweils an den Ethernet-Karten der Computer
und an den von 1 bis 4 nummerierten LAN-Ports des Routers angeschlossen sind. Der
Begriff „Ethernet“, mit dem Netzwerkkomponenten wie Kabel und Netzwerkkarten bezeichnet werden, weist darauf hin, dass Ethernet der Typ des Netzwerks ist, das Sie einrichten.
In der Dokumentation des Routers bezeichnet „Ethernet“ alle Netzwerkkomponenten, die
Computerdaten mit 10 bis 100 Mbit/s übertragen. (10 und 100 Mbit/s sind die von den
Netzwerkgeräten verwendeten Übertragungsraten. Wenn Daten mit 10 Mbit/s übertragen
werden, entspricht dies dem Inhalt von mehr als sieben Disketten pro Sekunde!
Netzwerkkomponenten, die mit 100 Mbit/s arbeiten, transportieren die Daten sogar noch
zehnmal schneller!)
60
Das Setup des
Routers ist dem
in der oben stehenden Abbildung für Windows-PCs gezeigten Setup vergleichbar. Mit dem Router können Sie
Ihre Kabel- oder DSL-Verbindung für mehrere Computer in Ihrem privaten oder geschäftlichen
Umfeld freigeben. Eine solche Struktur wird LAN (Local Area Network) genannt.
Diese Kurzanleitung vermittelt eine Übersicht der Komponenten zur Einrichtung eines einfachen privaten oder geschäftlichen Netzwerks. In den nächsten drei Abschnitten erfahren
Sie, wie Sie Ihre Geräte einrichten und konfigurieren müssen, um über einen gemeinsamen
Hochgeschwindigkeitszugang zum Internet zu verfügen.
Schritt 1: Anschließen des Routers
In diesem Schritt schließen Sie den Router an Ihr Kabel- oder DSL-Modem an. Anschließend
verbinden Sie Ihre PCs mit dem Router.
PCs können mit dem Router auch kabellos kommunizieren. Wenn Sie Ihre kabellosen PCs
und den Router mit denselben Wireless-Einstellungen konfigurieren, können Sie diese
kabellosen PCs in Ihr vorhandenes Ethernet-Netzwerk einbinden.
Schritt 2: Konfigurieren der PCs
Ein besonders interessanter Aspekt ist, dass der Router die gemeinsame Nutzung Ihrer
Kabel- oder DSL-Internetverbindung ermöglicht. Hierzu müssen Sie lediglich Ihr Kabel- oder
DSL-Modem über ein Ethernet-Kabel an den WAN-Port des Routers anschließen. (WAN ist
die Abkürzung von „Wide Area Network“, d. h. Weitbereichsnetzwerk.) Das Internet weist
als globales Netzwerk die größte Ausdehnung aller Netzwerke auf! Die an den Router
angeschlossenen PCs können diese Verbindung nutzen.
Schritt 3: Konfigurieren des Routers
Hier ist beschrieben, wie Sie Ihre PCs konfigurieren müssen, um mit dem Router zu kommunizieren.
In diesem Schritt lernen Sie grundlegende Einstellungen des Routers kennen, die den Betrieb
mit Ihrem Kabel- oder DSL-Modem und Ihren ISP-Einstellungen ermöglichen.
Hinweis: Diese Kurzanleitung beschreibt die Einrichtung des Routers mit EthernetKabeln. Der Router kann zwar auch über eine kabellose Verbindung eingerichtet werden. In dieser Kurzanleitung werden jedoch keine Details zur kabellosen Einrichtung des
Routers beschrieben. Wenn Sie den Router über eine kabellose Verbindung einrichten
möchten, finden Sie weitere Informationen auf der Linksys-Website unter
www.linksys.com.

Schritt 1: Anschließen des Routers
Wireless Access Point-Router mit 4-Port-Switch
B. Verbinden Sie mit einem Ethernet-Kabel den
LAN- bzw. Ethernet-Port des Kabel- oder
DSL-Modems mit dem WAN-Port des
Routers.
In Schritt 1 verbinden Sie den Router mit Ihrem Kabel- oder DSL-Modem und Ihren privaten oder geschäftlichen Computern.
Vergewissern Sie sich zunächst, dass alle Geräte ausgeschaltet sind, mit denen Sie arbeiten werden, also die PCs, das Modem und der Router.
A. Soweit Sie dies nicht bereits durchgeführt haben, schließen Sie jetzt Ihr Kabel- oder
DSL-Modem richtig an. Für den Kabelbetrieb ist eine Koaxialbuchse (Abbildung A1) und
für den DSL-Betrieb eine Telefonbuchse vorgesehen (Abbildung A2). (Folgen Sie den
Anweisungen im Installationshandbuch Ihres Kabel- oder DSL-Modems.)
C. Schließen Sie ein Ethernet-Kabel
an die Ethernet-Karte Ihres PCs
an. Schließen Sie das andere
Ende des Kabels an einen LANPort des Routers an. Wiederholen
Sie diesen Vorgang für jeden
weiteren PC, den Sie an den
Router anschließen möchten.
C1
Hinweis: Ist die Ethernet-Karte Ihres PCs nicht eingerichtet, finden Sie weitere
Informationen in der Dokumentation der Ethernet-Karte.
Um die Installation zu vereinfachen, beginnen
Sie mit dem LAN-Port 1 des Routers.
Schließen Sie anschließend Port 2, Port 3 und
schließlich Port 4 an.
Wenn Sie mehr als vier PCs an den Router
anschließen möchten, müssen Sie an den
Uplink-Port des Routers einen Hub oder
Switch anschließen (wenn Sie den UplinkPort verwenden, ist Port 4 nicht verfügbar).
Weitere Informationen zum UplinkVerfahren finden Sie im Benutzerhandbuch
auf der CD des Setup-Assistenten.
C2
D. Verbinden Sie das Netzgerät mit dem Stromversorgungsanschluss des Routers.
Schließen Sie das Netzgerät an einer Netzsteckdose an. Schalten Sie das Kabel- oder
DSL-Modem ein. Schalten Sie dann den ersten PC ein, den Sie zum Konfigurieren des
Routers verwenden möchten.
Fahren Sie mit Schritt 2 fort: Konfigurieren Sie die PCs (siehe nächste Seite).

A. Klicken Sie auf die Schaltfläche Start, klicken
Sie auf Einstellungen, und öffnen Sie die
Systemsteuerung. Doppelklicken Sie hier auf
das Symbol Netzwerk, um das Fenster
Netzwerk zu öffnen.
In Schritt 2 werden Sie die einzelnen Computer für die Kommunikation mit dem Router konfigurieren.
Hierzu müssen Sie die Netzwerkeinstellungen Ihres PCs so einstellen, dass eine IP-Adresse
(auch TCP/IP-Adresse genannt) automatisch bezogen wird. Computer verwenden IPAdressen zur gegenseitigen Kommunikation über ein Netzwerk oder das Internet.

Wireless Access Point-Router mit 4-Port-Switch
Konfigurieren der Wireless-Sicherheit
Hinweis: Die WEP-Verschlüsselung ist ein zusätzliches
Mittel zur Datensicherheit und für die Funktion des
Routers nicht erforderlich.
WEP steht als Abkürzung für „Wired Equivalent Privacy“, ein Verschlüsselungsverfahren zum Schutz Ihrer kabellosen Datenkommunikation. WEP verwendet
eine Kombination aus 64-Bit- oder 128-Bit-Schlüsseln, um den Zugriff auf das
Netzwerk zu kontrollieren und die einzelnen Datenübertragungen sicher zu verschlüsseln. Um eine Datenübertragung zu decodieren, muss jeder Access Point im Netzwerk
einen identischen 64-Bit- bzw. 128-Bit-Schlüssel verwenden. Höhere Verschlüsselungsstärken gewährleisten zwar eine höhere Sicherheit, aufgrund der Komplexität der
Verschlüsselung können sie jedoch eine verminderte Netzwerkleistung bewirken.
Vielleicht haben Sie im Zusammenhang mit der WEP-Verschlüsselung auch den Begriff
„40-Bit“ gehört. Auch damit ist die 64-Bit-WEP-Verschlüsselung gemeint. Diese
WEP-Verschlüsselungsstufe wird „40-Bit“ genannt, weil sie einen geheimen 40-BitSchlüssel zusammen mit einem 24-Bit-Initialisierungsvektor verwendet (40 + 24 = 64).
Die Hersteller von Wireless-Geräten verwenden beide Bezeichnungen. Linksys bezeichnet diese Verschlüsselungsstufe mit „64-Bit“.
Vergewissern Sie sich, dass Ihr kabelloses Netzwerk funktioniert, bevor Sie versuchen,
die WEP-Verschlüsselung zu konfigurieren.
Ein nach dem 128-Bit-WEP-Verfahren verschlüsseltes kabelloses Netzwerk kann
NICHT mit einem nach dem 64-Bit-WEP-Verfahren verschlüsselten kabellosen
Netzwerk kommunizieren. Vergewissern Sie sich daher, dass alle Ihre kabellosen Geräte
die gleiche Verschlüsselungsstufe verwenden. Alle kabellosen Geräte, die der Norm
802.11b entsprechen, unterstützen 64-Bit-WEP.
Linksys empfiehlt nicht nur, WEP zu aktivieren, sondern darüber hinaus auch folgende
Sicherheitsmaßnahmen zu ergreifen:
• Ändern der SSID von der Vorgabe „linksys“
• Regelmäßiges Ändern des WEP-Schlüssels
Hinweis: Möchten Sie die WEP-Verschlüsselung aktivieren, müssen zuerst die WirelessFunktionen aktiviert sein. Wählen Sie auf der Registerkarte Wireless (Kabellos) des
Routers die Option Enable (Aktivieren), bevor Sie fortfahren.
76
77
Instant Wireless™-Serie
Die folgenden Schritte zeigen Ihnen, wie Sie die WEP-Verschlüsselung einsetzen.
1. Wählen Sie auf der Registerkarte Setup des Web-Dienstprogramms im Abschnitt
WEP die Option Mandatory (Obligatorisch).
2. Klicken Sie auf die Schaltfläche WEP Key Setting (WEP-Schlüsseleinstellung),
um den Typ und die Stufe der WEP-Verschlüsselung einzustellen.
3. Nun wird gegebenenfalls das in Abbildung C-1 dargestellte Dialogfeld angezeigt, in
dem bestätigt wird,
dass Sie die WEPVe r s c h l ü s s e l u n g
aktivieren. Klicken
Sie auf die Schaltfläche OK, um fortzufahren.
Abbildung C-1
4. Nun wird das in
Abbildung C-2 dargestellte Dialogfeld angezeigt. Hier können Sie Ihre WEPVerschlüsselungseinstellungen wählen.
Wireless Access Point-Router mit 4-Port-Switch
•
WEP (64-Bit oder 128-Bit) Wählen Sie die Verschlüsselungsstufe aus dem
Dropdownfeld. Die 128-Bit-WEP-Verschlüsselung von Linksys ist herstellerspezifisch und möglicherweise nicht kompatibel mit der WEP-Verschlüsselung anderer
Hersteller.
Hinweis: Um die WEP-Verschlüsselung einsetzen zu können, muss diese bei
allen Access Points in Ihrem kabellosen Netzwerk aktiviert und auf dieselbe
Schlüsseleinstellung eingestellt sein.
Der WEP-Schlüssel wird nach einem der folgenden beiden Verfahren generiert:
1. Durch Verwendung eines Kennwortsatzes
a. Geben Sie einen Kennwortsatz als benutzerdefiniertes Kennwort in das Feld
Passphrase (Kennwortsatz) ein. Der Kennwortsatz kann bis zu 31 Buchstaben,
Sonderzeichen und Ziffern enthalten. Leerzeichen sind nicht zulässig.
b. Klicken Sie auf die Schaltfläche Generate (Generieren), um einen Schlüssel zu
erstellen. Wenn Sie die 64-Bit-Verschlüsselung gewählt haben, besteht der
Schlüssel aus 10 Ziffern, bei der 128-Bit-Verschlüsselung aus 26 Ziffern. Mit
diesem Schlüssel werden die zwischen dem Router und den kabellosen PCs des
Netzwerks übertragenen Daten verschlüsselt bzw. entschlüsselt.
Im Feld Key (Schlüssel) werden möglicherweise nicht alle Ziffern angezeigt. In
diesem Fall klicken Sie mit der Maus an eine beliebige Stelle in diesem Feld.
Verschieben Sie den Mauszeiger nach rechts, um den Rest des Schlüssels
anzuzeigen. Der gesamte Schlüssel muss exakt so übernommen werden, wie er
angezeigt wird.
2. Alternativ können Sie einen Schlüssel auch manuell eingeben.
Notieren Sie sich den Kennwortsatz bzw. den manuellen Schlüssel. Sie benötigen diese
Angaben für die anderen kabellosen Geräte im Netzwerk, da bei diesen immer derselbe
WEP-Schlüssel eingegeben werden muss.
Nachdem Sie das Verschlüsselungsverfahren ausgewählt und entweder den
Kennwortsatz oder einen manuellen Schlüssel eingegeben haben, klicken Sie auf die
Schaltfläche Apply (Übernehmen). Damit ist die Verschlüsselungskomponente des
Setup abgeschlossen.
Hinweis: Unter Windows XP wird der vom Router generierte 128-BitSchlüssel „104-Bit-Schlüssel (26 Ziffern)“ genannt und der vom
Router generierte 64-Bit-Schlüssel heißt „40-Bit-Schlüssel
(10 Ziffern)“.

Introduzione
Grazie per aver scelto Instant Wireless™ Wireless Access Point Router. Questo router consentirà di configurare una rete con i propri PC e di condividere il collegamento a Internet.
In che modo il router realizza tutto ciò? Collegando il modem cable o DSL direttamente al
router e utilizzando le porte Ethernet del router per collegare i PC, è come se ogni PC fosse
collegato direttamente a Internet. In questo modo, è possibile disporre di diversi PC in grado
di utilizzare simultaneamente un collegamento Internet. Inoltre, poiché è un Access Point, il
router può creare un ponte di collegamento tra la rete Ethernet e i PC Wireless.
Wireless Access Point Router con switch a 4 porte
Le istruzioni fornite in questa Guida di avviamento rapido facilitano il collegamento al router,
la configurazione dei PC e la configurazione del router nella rete. Tali istruzioni dovrebbero
essere sufficienti per configurare e mettere in esecuzione una rete di base, condividendo l’accesso a Internet. Il router dispone inoltre di funzioni più avanzate il cui utilizzo però è consigliato solo a chi ha familiarità con router e reti. Questi e altri problemi sono trattati nel
Manuale dell’utente sul CD-ROM di Setup Wizard (Installazione guidata).
Quanto segue è ciò che si andrà a configurare
Qual è il significato di tutto ciò quindi?
Le reti sono strumenti utili per la condivisione delle risorse del computer. È possibile
accedere a una stampante da computer differenti e accedere ai dati ubicati sull’unità disco
rigido di un altro computer. Le reti vengono inoltre utilizzate per i videogiochi in modalità
multiplayer. Non sono quindi destinate solamente ad un uso domestico e di ufficio, ma
hanno anche una funzione ludica.
I PC collegati alle quattro porte LAN del router, se configurati in modo appropriato, creano
una LAN o Local Area Network (rete locale). Vengono collegati con un cavo Ethernet inserito nell’adattatore Ethernet del computer ad un’estremità e in una delle porte LAN del router
(con numero progressivo da uno a quattro) all’altra estremità. Il termine “Ethernet” viene
utilizzato per fare riferimento agli accessori di rete, come cavi e adattatori, poiché il termine
Ethernet fa riferimento al tipo di rete che si sta configurando. Nella documentazione relativa al router, il termine Ethernet fa riferimento agli accessori che trasferiscono i dati del
computer a una velocità compresa tra 10 Mbps e 100 Mbps. I termini 10 Mbps e 100 Mbps
fanno riferimento alla velocità utilizzata dai dispositivi di rete. Il trasferimento dei dati alla
velocità di 10 Mbps, è equivalente al trasferimento del contenuto di oltre sette floppy disk
al secondo. Gli accessori di rete che funzionano alla velocità di 100 Mbps trasferiscono i dati
a una velocità 10 volte superiore.
L’impostazione
del router è
simile a quella
mostrata nella
figura precedente per qualsiasi PC Windows. Il router consente di condividere la connessione cable o DSL
tra più computer a casa o in ufficio. Questo tipo di connessione è definito Local Area Network
(rete locale) o LAN.
Questa Guida di avviamento rapido fornisce un quadro generale di ciò che occorre per
impostare una rete di base in casa o in ufficio. Nelle tre sezioni successive viene spiegato
come impostare e configurare i propri apparecchi per consentire un accesso a Internet condiviso ad alta velocità.
Passaggio 1: Collegamento del router
I PC possono inoltre interagire con il router in modalità Wireless. Configurando i PC in
modalità Wireless con le stesse impostazioni Wireless del router, è possibile creare un ponte
di collegamento tra i PC in modalità Wireless, integrandoli comunque nella rete Ethernet
esistente.
Tuttavia, la funzione più importante del router è che consente di condividere il collegamento cable o DSL. Ciò viene effettuato collegando il modem cable o DSL alla porta WAN del
router con un cavo Ethernet. (WAN è l’acronimo di Wide Area Network). Internet è una rete
che, essendo globale, ricopre un’area vastissima. I PC collegati al router condividono tale
collegamento.
L’utente viene assistito nel processo di collegamento del router al modem cable o DSL. Viene
quindi mostrato in che modo i PC sono collegati al router.
Passaggio 2: Configurazione dei PC
Viene descritto in che modo i PC sono configurati per comunicare con il router.
Passaggio 3: Configurazione del router
L’utente viene assistito in alcune impostazioni di base del router, che ne consentono il funzionamento con il modem cable o DSL e le impostazioni del proprio ISP.
Nota: questa Guida di avviamento rapido indicherà all’utente le modalità di configurazione del router con cavi Ethernet. Mentre il router può essere configurato attraverso
un collegamento Wireless, i dettagli relativi alla configurazione del router in modalità
Wireless non verranno approfonditi in questa Guida di avviamento rapido. Gli utenti che
desiderassero configurare il router attraverso il collegamento Wireless, dovrebbero fare
riferimento al sito Web di Linksys: www.linksys.com.

B. Utilizzando un cavo Ethernet, collegare la
porta LAN o Ethernet del modem cable o
DSL alla porta WAN del router.
Nel passaggio 1, si collegherà il router al modem cable o DSL e ai computer di casa o di
ufficio.
Innanzitutto, accertarsi che tutti gli apparecchi da utilizzare, inclusi i PC, il modem e il router,
siano scollegati dalla fonte di alimentazione.
A. Se non è già stato fatto, collegare correttamente il modem cable o DSL, ovvero utilizzando il jack coassiale con il modem cable (Figura A1) o il jack telefonico con il modem
DSL (Figura A2). Seguire le istruzioni fornite nel manuale di installazione allegato al
modem cable o DSL.
C. Collegare un cavo Ethernet all’adattatore Ethernet del PC.
Collegare l’altra estremità del
cavo a una delle porte LAN del
router. Ripetere questo processo
per ogni PC che si desidera collegare al router.
C1
Nota: se l’adattatore Ethernet del PC non è configurato, fare riferimento alla documentazione relativa all’adattatore Ethernet per ulteriori informazioni.
Per semplicità di installazione, iniziare con la
Porta LAN 1 sul router, proseguire con la
Porta 2, la Porta 3 e per finire con la Porta 4.
Se si stanno collegando più di quattro PC al
router, sarà necessario collegare un hub o
switch alla porta Uplink del router (se si utilizza la porta Uplink, non è possibile utilizzare la Porta 4). Per informazioni sul collegamento tramite porta Uplink, fare riferimento al Manuale dell’utente contenuto nel
CD-ROM dell’Installazione guidata.

Configurazione della protezione Wireless
Nota: la crittografia WEP è una misura di protezione dati
aggiuntiva e non essenziale per il funzionamento del
router.
WEP, un acronimo di Wired Equivalent Privacy, è un metodo di crittografia utilizzato
per proteggere le comunicazioni dei dati in modalità Wireless. WEP utilizza una combinazione di chiavi a 64 bit o 128 bit per fornire il controllo di accesso alla rete e per
fornire la protezione di tipo crittografico ad ogni trasmissione di dati. Per decodificare
una trasmissione di dati, ogni postazione della rete deve utilizzare una chiave a 64 bit o
a 128 bit identica. Livelli superiori di crittografia comportano livelli più elevati di protezione, tuttavia, a causa della complessità della crittografia, potrebbero comportare un
minore rendimento della rete.
Quando si parla di crittografia WEP, ricorre a volte il termine “40 bit” . Si tratta semplicemente di un altro termine che sta ad indicare la codifica WEP a 64 bit. Questo livello di crittografia WEP è stato denominato a 40 bit poiché si serve di una chiave segreta a 40 bit unitamente a un vettore di inizializzazione a 24 bit (40 + 24 = 64). È possibile che i fornitori di accessori Wireless utilizzino una denominazione differente.
Linksys utilizza il termine “64 bit” quando fa riferimento a questo livello di crittografia.
Accertarsi che la rete Wireless sia funzionante prima di tentare la configurazione della
crittografia WEP.
Una rete Wireless con crittografia WEP a 128 bit NON comunicherà con una rete
Wireless con crittografia WEP a 64 bit. Pertanto, accertarsi che tutti i dispositivi
Wireless stiano utilizzando lo stesso livello di crittografia. Tutti i dispositivi Wireless
conformi allo standard 802.11b supporteranno la crittografia WEP a 64 bit.
Oltre ad abilitare la crittografia WEP, Linksys raccomanda inoltre le implementazioni di
protezione seguenti:
• Modificare l’SSID predefinito “linksys”
• Modificare la chiave WEP regolarmente
Nota: per poter abilitare la Crittografia WEP, è necessario prima abilitare le
funzionalità Wireless. Selezionare Enable (Abilita) sulla scheda Wireless del
router prima di continuare.

•
WEP (64 Bit o 128 Bit) Selezionare il livello di crittografia dalla casella a discesa.
La crittografia WEP a 128 bit è univoca per Linksys e potrebbe andare in conflitto
con altre forme di crittografia WEP di altri fornitori.
Nota: per poter utilizzare la crittografia WEP, tutte le postazioni nella
rete Wireless devono avere il protocollo WEP abilitato e configurato
con la stessa configurazione della chiave.
La chiave di crittografia WEP viene generata in uno dei seguenti modi:
1. È possibile creare una chiave di crittografia utilizzando una Passphrase.
a. Immettere una Passphrase, una password definita dall’utente, nel campo
Passphrase. La Passphrase può contenere un massimo di 31 lettere, simboli e
numeri. Non è possibile utilizzare spazi.
Figura C-1
4. Ciò porterà alla visualizzazione della schermata riportata nella figura C-2. Da tale
schermata, verranno scelte le impostazioni di crittografia WEP.
b. Fare clic sul pulsante Generate (Genera) per creare una chiave. La chiave sarà
costituita da 10 cifre se è stata scelta una crittografia a 64 -bit o da 26 cifre se è
stata scelta una crittografia a 128 bit. Questa chiave verrà utilizzata per codificare e decodificare i dati scambiati tra il router e i PC Wireless della rete.
È possibile che il campo Key (Chiave) non visualizzi tutte le cifre. Con il mouse,
fare clic in qualsiasi punto del campo Key (Chiave). Spostare il cursore sulla
destra per visualizzare il resto della chiave. Accertarsi di aver annotato l’intera
chiave ESATTAMENTE nel modo in cui viene visualizzata.
2. È possibile immettere la chiave di crittografia manualmente.
Prendere nota della Passphrase o della chiave manuale (Manual Key). Sarà necessaria
per gli altri dispositivi Wireless presenti nella rete, poiché è necessario immettere la
stessa chiave di crittografia WEP per tutti i dispositivi Wireless presenti nella rete.
Una volta scelto il metodo di crittografia a chiavi e una volta immessa la Passphrase o
la chiave manuale, fare clic sul pulsante Apply (Applica) e la parte relativa alla crittografia della configurazione è completata.
Nota: in Windows XP, una chiave a 128 bit generata dal router,
verrà denominata chiave a “104 bit (26 cifre)” e una chiave a
64 bit verrà denominata chiave a “40 bit (10 cifre)”.

Introdução
Obrigado por escolher o router de ponto de acesso sem fios Instant Wireless™. Este router
irá permitir-lhe configurar os seus PCs em rede e partilhar a ligação à Internet.
Como é que o router lhe permite tudo isto? Ligando o modem por cabo ou DSL directamente
ao router e utilizando as portas Ethernet do router para ligar os PCs, como se cada PC
estivesse directamente ligado à Internet. Desta forma, uma ligação à Internet pode ser utilizada simultaneamente por vários PCs. Além disso, por ser também um ponto de acesso, o
router pode estabelecer uma ponte entre a rede Ethernet e os PCs sem fios.
Router de ponto de acesso sem fios com switch de 4 portas
Utilize as instruções neste manual de iniciação rápida para ligar o router, configurar os seus
PCs e configurar o router na sua rede. Estas instruções devem ser suficientes para colocar
uma rede básica em funcionamento e partilhar o acesso à Internet. O router também vem
equipado com funções mais avançadas, mas estas não devem ser utilizadas sem uma compreensão mais aprofundada do funcionamento dos routers e das redes. Estas e outras
questões são explicadas no manual do utilizador no CD-ROM do assistente de configuração.
Esquema de configuração:
Mas o que significa tudo isto?
As redes são ferramentas úteis para partilhar recursos informáticos. É possível aceder a
uma impressora a partir de diferentes computadores, bem como a dados localizados no
disco rígido de outro computador. As redes são também usadas para jogos de computador
multi-jogador. Então, conclui-se que as redes não só são muito úteis em casa e no
escritório, como podem ser também muito divertidas.
Os PCs ligados às quatro portas LAN do router, depois de adequadamente configurados,
constituem uma rede local (LAN: Local Area Network). Os computadores são ligados através
de um cabo Ethernet que é ligado, numa extremidade, ao adaptador de Ethernet do computador e, na outra extremidade, a uma das portas LAN do router (numeradas de um a quatro). O termo “Ethernet” é utilizado para designar os acessórios de rede, tais como cabos e
adaptadores, porque Ethernet se refere ao tipo de rede que está a ser configurado. Na documentação do router, Ethernet refere-se aos acessórios que transferem os dados do computador de 10Mbps a 100Mbps. (10Mbps e 100Mbps referem-se às velocidades utilizadas
pelos dispositivos de rede. Ao transferir dados a 10Mbps, está a mover o equivalente a mais
de sete disquetes por segundo! Os acessórios de rede que funcionam a 100Mbps movem
os dados dez vezes mais rapidamente!)
Os PCs também podem interagir com o router sem fios. Ao configurar os PCs sem fios utilizando as mesmas definições sem fios do router, é possível estabelecer uma ponte entres
estes PCs sem fios, integrando-os na rede Ethernet existente.
A funcionalidade mais espantosa do router é, talvez, o facto de permitir partilhar a ligação
por cabo ou DSL. Poderá usufruir desta funcionalidade ligando o modem por cabo ou DSL
à porta WAN do router por meio de um cabo Ethernet (WAN refere-se a uma rede alargada:
Wide Area Network). A Internet é uma rede global que abrange a maior área possível! Os
PCs ligados ao router partilham esta ligação.
A configuração do router é semelhante à que é mostrada na figura acima, para qualquer PC
a executar o Windows. O router permite-lhe partilhar a sua ligação por cabo ou DSL entre
vários computadores em casa ou no escritório. Esta é chamada uma rede local ou LAN (Local
Area Network).
Este manual de iniciação rápida fornece-lhe uma perspectiva geral do que é necessário para
configurar uma rede básica em casa ou no escritório. As três secções que se seguem explicam como configurar o equipamento de modo a permitir a partilha do acesso de alta velocidade à Internet.
Passo 1: Ligação do router
É explicado o processo de ligação do router ao modem por cabo ou DSL. Em seguida, é
mostrado como os PCs são ligados ao router.
Passo 2: Configuração dos PCs
É descrito como os PCs são configurados para comunicar com o router.
Passo 3: Configuração do router
São explicadas algumas das definições básicas do router para que funcione com o modem
por cabo ou DSL e com as definições do ISP.
Nota: Este manual de iniciação rápida irá ajudá-lo a configurar o router com cabos
Ethernet. Apesar de ser possível configurar o router através de uma ligação sem fios,
este manual de iniciação rápida não fornece pormenores sobre como configurar o
router sem fios. Os utilizadores que pretendem configurar o router através de uma ligação sem fios deverão consultar o Web site da Linksys em www.linksys.com.

Passo 1: Ligação do router
Router de ponto de acesso sem fios com switch de 4 portas
B. Utilizando um cabo Ethernet, ligue a porta
LAN ou Ethernet do modem por cabo ou DSL
à porta WAN do router.
No passo 1, irá ligar o router ao modem por cabo ou DSL e aos computadores de
casa ou do escritório.
Primeiro, certifique-se de que todos os dispositivos com que está a trabalhar estão
desligados da corrente incluindo os PCs, o modem e o router.
A. Se ainda não o fez, ligue o modem por cabo ou DSL à ligação adequada—a tomada
coaxial para cabo (figura A1) ou a tomada de telefone para DSL (figura A2) (Siga as
instruções do manual de instalação do modem por cabo ou DSL.)
C. Ligue um cabo Ethernet ao adaptador de Ethernet do PC. Ligue a
outra extremidade do cabo a uma
das portas LAN do router. Repita
este processo para cada PC que
pretender ligar ao router.
C1
Nota: Se o adaptador de Ethernet do PC não estiver configurado, consulte a documentação do adaptador de Ethernet para obter mais informações.
De modo a facilitar a instalação, comece pela
porta LAN 1 do router, utilize em seguida a
porta 2, depois a porta 3 e, finalmente, a
porta 4.
Se pretender ligar mais de quatro PCs ao
router, será necessário ligar um hub ou
switch à porta Uplink do router (se utilizar a
porta Uplink, não poderá utilizar a porta 4).
Para obter informações sobre o Uplink, consulte o manual do utilizador no CD-ROM do
assistente de configuração.
C2
D. Ligue o adaptador de corrente à porta de alimentação do router. Em seguida, ligue o adaptador de corrente a uma tomada eléctrica. Ligue o modem por cabo ou DSL. Em seguida, ligue o primeiro PC que pretender utilizar ao configurar o router.

• Cada LED do router irá acender por cada ligação bem estabelecida na parte de trás do
router—quer seja um cabo Ethernet ou um cabo de alimentação.
Por exemplo, os seguintes LEDs acendem quando se liga um computador e um modem
por cabo ou DSL:
Quando o router é ligado (o adaptador de corrente está ligado ao
router), o LED Power acende.
Quando um cabo Ethernet é correctamente ligado entre um PC e a porta 4 do
router, os LEDs Link/Act, Ful/Col e 100 na coluna 4 acendem.
A ligação de um modem por cabo ou DSL faz com que o LED WAN Link acenda.

• O LED WAN Link não está aceso. O que devo verificar?
•
Verifique se o cabo que está a usar entre o modem por cabo ou DSL e o router é
o que foi fornecido com o modem. Consoante o tipo de ligação utilizada pelo
modem, poderá necessitar de um cabo Ethernet directo (‘straight-through’) ou
cruzado (‘crossover’). O tipo directo é o mais comum.
• Algumas das luzes na parte da frente do router não acendem quando eu ligo um PC.
Apenas o LED Link/Act é necessário para que uma ligação funcione correctamente.
A. Em primeiro lugar, verifique se o modem por cabo ou DSL e os computadores estão correctamente ligados ao router. Consulte a pergunta n.º 2 para obter informações sobre

Configurar a segurança sem fios
Nota: A encriptação WEP é uma medida adicional de
segurança de dados não essencial para o funcionamento
do router.
Sendo um acrónimo para privacidade equivalente com fios (WEP: Wired Equivalent
Privacy), este constitui um método de encriptação utilizado para proteger as comunicações de dados sem fios. A WEP utiliza uma combinação de chaves de 64 ou 128 bits
para proporcionar o controlo do acesso à sua rede e segurança de encriptação para todas
as transmissões de dados. Para descodificar uma transmissão de dados, cada ponto na
rede tem de utilizar uma chave de 64 ou 128 bits idêntica. Níveis de encriptação superiores significam maiores níveis de segurança, mas devido à complexidade da encriptação, podem também significar uma diminuição no desempenho da rede.
Também poderá ter ouvido falar no termo “40 bits” utilizado em associação com encriptação WEP . Este é outro termo para encriptação WEP de 64 bits . Este nível de encriptação WEP foi apelidado de 40 bits porque utiliza uma chave secreta de 40 bits juntamente com um vector de inicialização de 24 bits (40 + 24 = 64). Os fornecedores de
equipamento sem fios poderão usar qualquer um dos nomes. A Linksys utiliza o termo
“64 bits” para se referir a este nível de encriptação.
Certifique-se de que a rede sem fios está a funcionar antes de tentar configurar a encriptação WEP.
Uma rede sem fios com encriptação WEP de 128 bits NÃO comunicará com uma rede
sem fios com encriptação WEP de 64 bits. Por isso, certifique-se de que todos os dispositivos sem fios utilizam o mesmo nível de encriptação. Todos os dispositivos sem
fios em conformidade com a norma 802.11b suportam WEP de 64 bits.
Para além da activação da WEP, a Linksys também recomenda a implementação das
seguintes medidas de segurança:
• Alteração do SSID cujo valor predefinido é “linksys”
• Alteração regular da chave WEP
Nota: Para activar a encriptação WEP, é necessário activar, em primeiro lugar,
as funções sem fios. Seleccione Enable (Activar) no separador ‘Wireless’
(Sem fios) antes de prosseguir.
132
133
Série Instant Wireless™
Os passos que se seguem irão mostrar como utilizar a encriptação WEP
1. A partir do separador ‘Setup’ (Configuração) do utilitário baseado na Web, seleccione Mandatory (Obrigatório) na secção WEP.
2. Prima o botão WEP Key Setting (Definição da chave WEP) para definir o tipo e o
nível da encriptação WEP.
Router de ponto de acesso sem fios com switch de 4 portas
•
WEP (64B ou 128B) Seleccione o nível de encriptação a partir da caixa pendente.
A encriptação WEP de 128 bits é exclusiva da Linksys e pode entrar em conflito
com a encriptação WEP de outros fornecedores.
Nota: Para utilizar a encriptação WEP, todos os pontos na rede sem
fios têm de ter a WEP activada e possuir a mesma definição de chave.
A chave de encriptação WEP é gerada de uma das seguintes formas:
3. Poderá aparecer o
ecrã apresentado na
figura C-1, a confirmar se pretende activar a encriptação
WEP. Prima o botão
OK para continuar.
1. O utilizador pode criar uma chave de encriptação utilizando uma Passphrase (Frasepasse).
a. Introduza uma frase-passe, uma palavra-passe definida pelo utilizador, no campo
Passphrase. A frase-passe pode conter até 31 letras, símbolos e números. Não é
possível utilizar espaços.
Figura C-1
4. Em seguida, será apresentado o ecrã mostrado na figura C-2. A partir daqui, poderá
escolher as suas definições de encriptação WEP.
b. Clique no botão Generate (Gerar) para criar uma chave. A chave terá 10 dígitos,
se escolher encriptação de 64 bits ou 26 dígitos, se escolher encriptação de 128
bits. Esta chave será utilizada para encriptar e desencriptar os dados enviados
entre o router e os PCs sem fios da rede.
O campo ‘Key’ (Chave) pode não apresentar todos os dígitos. Com o rato, clique
em qualquer parte no campo ‘Key’ (Chave). Mova o cursor para a direita para
ver o resto da chave. Certifique-se de que escreve toda a chave EXACTAMENTE da forma como é mostrada.
2. Pode introduzir a chave de encriptação manualmente.
Tome nota da frase-passe ou chave manual. Ela será necessária para os outros dispositivos sem fios da rede, uma vez que todos têm de possuir a mesma chave de encriptação
WEP.
Uma vez escolhido o método da chave de encriptação e introduzida a frase-passe ou
chave manual, clique no botão Apply (Aplicar) para concluir a parte do processo de
configuração destinada à encriptação.
Nota: No Windows XP, uma chave de 128 bits gerada pelo
router será designada por chave de “104 bits (26 dígitos)” e
uma chave de 64 bits gerada pelo router será designada por
chave de “40 bits (10 dígitos)” .

Introducción
Gracias por elegir el ruteador Access Point para conexiones inalámbricas con switch de 4
puertos Instant Wireless™. Este ruteador le permitirá configurar una red en su PC y,
además, compartir la conexión a Internet.
¿Cómo consigue el ruteador hacer todo esto? Al conectar un módem por cable o DSL al
ruteador y los PC a los puertos Ethernet de éste, cada PC queda configurado como si estuviera conectado directamente a Internet. De este modo, varios PC pueden compartir
simultáneamente una conexión a Internet. Además, puesto que también es Access Point
(punto de acceso), el ruteador puede conectar la red Ethernet a los equipos inalámbricos.
Ruteador Access Point para conexiones inalámbricas con conmutador de 4 puertos
Siga las instrucciones de esta Guía rápida para conectar el ruteador y configurar los PC y el
ruteador en la red. En estas instrucciones se explican todos los pasos necesarios para configurar y poner en marcha una red normal y compartir el acceso a Internet. El ruteador dispone
también de otras funciones más avanzadas, no obstante, no deberán utilizarse hasta no tener
un conocimiento más amplio de ruteadores y redes. Estos temas y otros se tratan en el
Manual del usuario del CD-ROM del Asistente para instalación.
Descripción de la configuración
¿Qué significa?
Las redes son herramientas muy útiles para compartir recursos. Permiten el acceso a una
impresora desde varios equipos o a los datos localizados en el disco duro de otros equipos.
Las redes también se utilizan para compartir videojuegos entre varios participantes. Por lo
tanto, no sólo son útiles para los hogares y las oficinas, sino que también pueden proporcionar diversión.
Los PC conectados a los cuatro puertos LAN del ruteador y configurados correctamente forman una LAN o red de área local. Se comunican mediante un cable Ethernet conectado al
adaptador Ethernet del equipo y a los puertos LAN del ruteador (numerados del uno al cuatro). Se utiliza la expresión “Ethernet” para referirse a los accesorios de la red, como cables
y adaptadores, ya que el tipo de red que va a configurar es Ethernet. En la documentación
del ruteador, Ethernet se refiere a los accesorios que transfieren datos informáticos entre
10 Mbps y 100 Mbps. (10 Mbps y 100 Mbps son las velocidades de transmisión de los dispositivos de la red. Una velocidad de transferencia de datos de 10 Mbps equivale a transferir siete disquetes por segundo. Los accesorios de red que funcionan a 100 Mbps transfieren los datos diez veces más rápido)
La configuración del ruteador para cualquier PC Windows es similar a la figura mostrada arriba. El ruteador permite compartir la conexión de un módem por cable o DSL con varios
equipos en casa en la oficina. Este tipo de conexión se denomina Red de área local o LAN.
En esta Guía rápida encontrará una descripción general de todos los pasos necesarios para
configurar una red normal en su casa o en la oficina. En los tres apartados siguientes se explica cómo conectar y configurar los equipos para que utilicen un acceso compartido de alta
velocidad a Internet.
Los PC también pueden interactuar con el ruteador mediante conexiones inalámbricas. Al
configurar los PC inalámbricos con los mismos parámetros que el ruteador, es posible interconectarlos e integrarlos en la red Ethernet existente.
Paso 1: Conexión del ruteador
Quizá, la función más importante del ruteador es la que permite compartir la conexión por
cable o DSL. Se consigue conectando el módem por cable o DSL al puerto WAN del ruteador
con un cable Ethernet. (WAN son las siglas en inglés de Red de área extensa.) Internet es
una red global que cubre el área más extensa. Los PC conectados al ruteador comparten
esta conexión.
Paso 2: Configuración de los PC
En este paso se describe el proceso de conexión del ruteador al módem por cable o DSL. A
continuación, se muestra cómo conectar los PC al ruteador.
En este paso se explica cómo configurar los PC para que puedan comunicarse con el ruteador.
Paso 3: Configuración del ruteador
En este paso se muestran los ajustes que hay que realizar en el ruteador para que pueda
conectarse con el módem por cable o DSL utilizando la información de su ISP.
Nota: En esta Guía rápida se explica cómo configurar el ruteador con cables
Ethernet. Aunque el ruteador puede configurarse para una conexión inalámbrica,
en esta Guía rápida no se incluyen los detalles para este tipo de conexión. Si
desea configurar el ruteador para una conexión inalámbrica, visite el sitio Web de
Linksys en la dirección www.linksys.com.

Ruteador Access Point para conexiones inalámbricas con conmutador de 4 puertos
Configuración de la seguridad inalámbrica
Nota: La encriptación WEP es una medida de seguridad
de datos adicional no necesaria para el funcionamiento
del ruteador.
Las siglas en inglés WEP (Wired Equivalent Privacy) significan Privacidad equivalente
al cableado, un sistema de protección de datos para las comunicaciones inalámbricas.
WEP emplea una combinación de claves de 64 o 128 bits para proporcionar control de
acceso a la red y seguridad encriptada para todas las transmisiones de datos. Para desencriptar una transmisión, todos los puntos de la red deben utilizar una clave idéntica de
64 o 128 bits. Cuanto más alto sea el nivel de encriptación, mayor será la seguridad,
aunque, debido a la complejidad de la encriptación, podría afectar negativamente al
rendimiento de la red.
Es posible que también haya oído la expresión “40 bits” relacionada con la encriptación
WEP. Se trata sencillamente de otro término utilizado para la encriptación WEP de 64
bits. Este nivel de encriptación WEP se denomina de 40 bits porque emplea una clave
secreta de 40 bits y un vector de iniciación de 24 bits (40 + 24 = 64). Los proveedores
de comunicaciones inalámbricas utilizan los dos nombres. Linksys usa la expresión “64
bits” para referirse a este nivel de encriptación.
Antes de empezar a configurar la encriptación WEP, compruebe que la red inalámbrica
funciona correctamente.
Una red inalámbrica con encriptación WEP de 128 bits NO puede comunicarse con otra
red que utilice la encriptación WEP de 64 bits. Por lo tanto, asegúrese de que todos los
dispositivos inalámbricos utilizan el mismo nivel de encriptación. Los dispositivos que
cumplen el estándar 802.11b son compatibles con la encriptación WEP de 64 bits.
Además de habilitar WEP, Linksys recomienda tomar las siguientes medidas de seguridad:
• Cambiar el SSID predeterminado “linksys” por otro distinto
• Cambiar la clave WEP regularmente
Nota: Para activar la encriptación WEP, debe activar antes las funciones
inalámbricas. Seleccione Enable (Activar) en la ficha Wireless (Inalámbricas)
del ruteador antes de continuar.
160
161
Instant Wireless™ Series
En los pasos siguientes se explica cómo utilizar la encriptación WEP
1. En la ficha Setup (Configuración) de la utilidad basada en Web, elija Mandatory
(Obligatorio) en la sección WEP.
2. Haga clic en el botón WEP Key Setting (Configuración de la clave WEP) para
definir el tipo y el nivel de encriptación WEP.
3. Es posible que aparezca una pantalla
como la que muestra
la Figura C-1 solicitando que confirme
la activación de la
encriptación WEP.
Pulse el botón
Aceptar para continuar.
Ruteador Access Point para conexiones inalámbricas con conmutador de 4 puertos
•
WEP (64Bit o 128B) Seleccione el nivel de encriptación en la lista desplegable. La
encriptación WEP de 128 bits es exclusiva de Linksys y podría interferir con la
encriptación WEP de otros fabricantes.
Nota: Para utilizar la encriptación WEP, todos los puntos de la red
inalámbrica deben tener activada la encriptación WEP y la misma
configuración de claves.
La clave de encriptación WEP se genera de una de estas dos formas:
1. Puede crear una clave de encriptación mediante una Frase clave.
a. Escriba la Frase clave, una contraseña definida por el usuario, en el campo
Passphrase (Frase clave). La Frase clave no debe superar los 31 caracteres entre
letras, símbolos y números, y no se pueden utilizar espacios.
Figura C-1
4. Se abre una pantalla como la que muestra la Figura C-2 en la que deberá seleccionar
los parámetros de la encriptación WEP.
b. Haga clic en el botón Generate (Generar) para crear la clave. La clave será de
10 dígitos si elige la encriptación de 64 bits o de 26 dígitos si elige la
encriptación de 128 bits. Esta clave se utilizará para encriptar y desencriptar los
datos transferidos entre el ruteador y la red inalámbrica de PC.
Es posible que el campo Key (Clave) no muestre todos los dígitos. Haga clic en
cualquier parte del campo Key y mueva el cursor hacia la derecha para ver el
resto de la clave. Anote la clave completa EXACTAMENTE como aparece.
2. También puede introducir manualmente la clave de encriptación.
Anote la Frase clave o la Clave manual. Necesita conservarla ya que es necesario introducir la misma clave de encriptación WEP en todos los dispositivos inalámbricos de la
red.
Cuando haya elegido el método de encriptación de claves y especificado la Frase clave
o la clave manual, haga clic en el botón Apply (Aplicar) para completar la configuración de la encriptación.
Nota: En Windows XP, una clave de 128 bits generada por el
ruteador se denomina clave de “104 bits (26 dígitos)” y una de
64 bits sería una clave de “40 bits (10 dígitos)” .

apartado anterior.
En los pasos siguientes se explica cómo activar la encriptación WEP y escribir manualmente la clave de encriptación de las tarjetas de PC inalámbricos para que el sistema
Windows XP pueda comunicarse sin cables con el ruteador.
En estos pasos se presupone que la unidad de CD-ROM tiene asignada la letra D y que

A typical router relies on a hub or a switch to share its Internet connection, but
the Linksys Wireless Access Point Router with 4-Port Switch channels this
connection through the blazing, full duplex speed of its built-in EtherFast®
10/100 4-Port Switch. This cutting-edge combination of wireless router and
switch technology eliminates the need to buy an additional hub or switch and
extends the range of your wireless network. Now your entire wireless network
can enjoy blazing broadband Internet connections supported by its robust
switched backbone. With the dual-function speed and power of the Wireless
Access Point Router with 4-Port Switch, your network will take off at speeds
faster than you ever imagined possible.
In this instance, the Router connects your Local Area Network (LAN), or the
group of PCs in your home or office, to the Wide Area Network (WAN) that is
the Internet. The Router processes and regulates the data that travels between
these two networks.
Features
The Router’s firewall (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your LAN, or network,
remains private. The Router protects your network by inspecting the first packet coming in from the WAN port before delivery to the final destination on the
LAN port. The Router inspects Internet port services like the web server, ftp
server, or other Internet applications, and, if allowed, it will forward the packet
to the appropriate PC on the LAN side.

IP Addresses
Dynamic IP Addresses
What’s an IP Address?
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers. These IP addresses are called “dynamic”
because they are only temporarily assigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs on to the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will assign
it a new dynamic IP address.
IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its “location,” or address, on the network. This applies to both the WAN and LAN connections.
There are two ways of assigning an IP address to your network devices.
Static IP Addresses
A static IP address is a fixed IP address that you assign manually to a PC or
other device on the network. Since a static IP address remains valid until you
disable it, static IP addressing insures that the device assigned it will have that
same IP address until you change it. Static IP addresses are commonly used
with network devices such as server PCs or print servers.
If you use the Router to share your cable or DSL Internet connection, contact
your ISP to find out if they have assigned a static IP address to your account.
If so, you will need that static IP address when configuring the Router. You can
get the information from your ISP.
Note: Since the Router is a device that connects two networks, it needs two
IP addresses—one for the LAN side, and one for the WAN side. In this User
Guide, you’ll see references to the “WAN IP address” and the “LAN IP
address.”
Since the Router has firewall security (NAT), only the Router’s WAN IP address
can be seen from the Internet.
However, even the WAN IP address can be blocked, so that the Router and
network seem invisible to the Internet—This is shown in the Filters section in
“Chapter 5: Using the Routers Web-Based Utility”.
For DSL users, many ISPs may require you to log on with a user name and
password to gain access to the Internet. This is called “Point to Point Protocol
over Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does not
have a phone number to dial into, and PPPoE is a dedicated high-speed connection. PPPoE also will provide the Router with a dynamic IP address to
establish a connection to the Internet.
DHCP (Dynamic Host Configuration Protocol) Servers
DHCP frees you from having to assign IP addresses manually every time a new
user is added to your network. PCs and other network devices using dynamic
IP addressing are assigned a new IP address by a DHCP server. The PC or network device obtaining an IP address is called the DHCP client. The Router’s
WAN port is, by default, set as a DHCP client.
DHCP servers can either be a designated PC on the network or another network
device, such as the Router. By default, a DHCP server is enabled on your
Router’s LAN ports. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one
DHCP server on your network, you will experience network errors, such as
conflicting IP addresses. To disable the Router’s DHCP function, see the
DHCP section in Chapter 3: Configuring the Router.
Note: Even if you assign a static IP address to a PC, other PCs can still use
DHCP’s dynamic IP addressing, as long as the static IP is not within the
DHCP range of the LAN IP Address.
If the Router’s DHCP function fails to provide a dynamic IP address for any
reason, please refer to Appendix A: Troubleshooting.

The Reset Button
The Wireless Access Point Router’s Ports
Pressing the Reset Button and holding it in for a few seconds will clear all
of the Router’s data and restore the factory defaults. This should be done
only if you are experiencing heavy routing problems, and only after you
have exhausted all of the other troubleshooting options. By resetting the
Router, you run the risk of creating conflicts between your PCs’ actual IP
Addresses and what the Router thinks their IP Addresses should be. You
may be forced to reboot each network PC.
If the Router locks up, simply press the reset button or power it down for
three to five seconds by removing the power cable from the Router’s
Power Port. Leaving the power off for too long could result in the loss of
network connections.

Chapter 2: Connecting the Router
Before You Start
Before plugging everything together, it’s always a good idea to have everything
you’ll need to get the Router up and running. Depending upon how you configure the Router in Chapter 4: Configuring the Router, you may need some of the
following values from your ISP:
When connecting through a Static IP connection, be sure to have 1) Your
broadband-configured PC’s fixed Internet IP Address, 2) Your broadbandconfigured PC’s Computer Name and Workgroup Name, 3) Your Subnet
Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.
Link
Green. This LED indicates a connection between the Router
and your broadband device or network.
When connecting through a PPPoE connection, be sure to have 1) Your
PPPoE User Name and 2) Your PPPoE Password.
Act
Green. This LED blinks when the Router is sending or
receiving data over the broadband (WAN) port.
Diag
Red. This LED indicates the Router’s self-diagnosis mode
during boot-up and restart. It will turn off upon completing
the diagnosis. If this LED stays on for an abnormally long
period of time, refer to the Troubleshooting Appendix.
The installation technician from your ISP should have left this information with
you after installing your broadband connection. If not, you can call your ISP to
request the data.
Once you have the above values, you can begin the Router’s installation and
setup.
Connecting Your Hardware Together and Booting Up
Once you are sure that you have the above values on hand, you can begin the
Installation and Setup of the Router.
1. Power everything down, including your PCs, your cable or DSL modem and
the Router.
2. Connect an Ethernet cable from one of
your PC’s Ethernet ports to one of the
Router’s LAN ports (as shown in Figure 21). Do the same with all the PCs you wish
to connect to the Router. (LAN Port 4 will
become inactive if you use the Uplink
port.)
In addition to accessing the Router through
an Ethernet connection, a wireless connec-
Figure 2-1
Instant WirelessTM Series
tion can be used to access the Router. See the “For Wireless Connections”
section that follows these connection instructions.
3. Connect another Ethernet cable from your
cable or DSL modem to the Router’s WAN
port (as shown in Figure 2-2).
4. Connect the Power Adapter (included) to
the Router’s Power port (as shown in
Figure 2-3) and plug the other end into a
power outlet.

5. Power on the cable or DSL modem. Verify
that the power is on by checking the Link LED in the WAN column on the
front of the Router. The Link LED will be illuminated if the power is on and
the modem is ready.
Wireless Access Point Router with 4-Port Switch
For Wireless Connections: In addition to accessing the Router through an
Ethernet connection, a wireless connection can be used to access the Router.
After powering on the Router and connecting it to your modem, enter the
Router’s IP Address in the Address field of your wireless PC’s web-browser as
follows: http://192.168.1.1 and press Enter.
Important: The Wireless Access Point Router with 4-Port Switch is
configured by default to work out of the box with all Linksys Wireless
Adapters. If you have changed the defaults on your Linksys Wireless
Adapters, or are using other wireless adapters, you must temporarily change your wireless adapter settings to: (SSID = linksys) in
order to initially access the Router wirelessly. After you have
accessed the Router with the default settings, you can change the
router settings to coincide with your Network settings and reset your
adapters.
Important: Some ISPs—most notably some cable providers—configure their networks so that you do not have to enter a full Internet
address into your web browser or e-mail application to reach your
home page or receive your e-mail. If your Internet home page
address is something very simple, such as “www”, rather than
“www.linksys.com”, or your e-mail server’s address is something similar to “e-mail” or “pop3”, rather than “pop.mail.linksys.com”, you
won’t be able to properly configure the Router until you determine the
actual Internet addresses of your Web and e-mail connections.
You must obtain this information prior to connecting the Router to
your network. You can obtain this information by contacting your ISP.
6. Press the Reset button on the back of the Router. Hold the button in for three
seconds, or until the Diag LED illuminates red. This restores the Router’s
default settings.
7. Power on your PC.
The Router is now connected. Continue to the next chapter to configure
your PCs.

Chapter 3: Configuring the PCs
Overview
These instructions will help you configure each of your computers to communicate with the Router.
To do this, you will need to configure your PC’s network settings to obtain an
IP (or TCP/IP) address automatically. Computers use IP addresses to communicate with each other across a network or the Internet.
You will need to know which operating system your computer is running, such
as Windows 95, 98, Millennium, 2000, or XP. You can find out by clicking the
Start button and then selecting the Settings option. (If your Start menu does n’t have a Settings option, you’re running Windows XP. You can select the
Control Panel directly from the Start Menu.) Then, click Control Panel and
double-click the System icon. Click the Cancel button when done.
Once you know which Windows operating system you are running, follow the
directions in this step for your computer’s operating system. If you PC is not
configured with the TCP/IP protocol, you will need to do this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your TCP/IP settings based on the type of Windows operating system you are using. Once
you've configured your computers, continue to Chapter 4: Configuring the
Router.

Instant WirelessTM Series
The Preset Applications are among the most widely used Internet applications
that may require forwarding. They include the following:
• FTP (File Transfer Protocol) A protocol used to transfer files over a TCP/IP
network (Internet, UNIX, etc.). For example, after developing the HTML
pages for a website on a local machine, they are typically uploaded to the
web server using FTP. FTP includes functions to log onto the network, list
directories, and copy files. It can also convert between the ASCII and
EBCDIC character codes. FTP operations can be performed by typing commands at a command prompt or via an FTP utility running under a graphical
interface such as Windows. FTP transfers can also be initiated from within a
web browser by entering the URL preceded by ftp://.
• Telnet A terminal emulation protocol commonly used on Internet and
TCP/IP-based networks. It allows a user at a terminal or computer to log onto
a remote device and run a program.
• SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on the
Internet. It is a TCP/IP protocol that defines the message format and the
message transfer agent (MTA), which stores and forwards the mail.
• DNS (Domain Name System) The way that Internet domain names are
located and translated into IP addresses. A domain name is a meaningful and
easy-to-remember “handle” for an Internet address.
• TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP protocol that has no directory or password capability.
• Finger A UNIX command widely used on the Internet to find out information about a particular user, such as a telephone number, whether the user is
currently logged on, and the last time the user was logged on. The person
being “fingered” must have placed his or her profile on the system in order
for the information to be available. Fingering requires entering the full
user@domain address.
• HTTP (HyperText Transport Protocol) The communications protocol used
to connect to servers on the World Wide Web. Its primary function is to
establish a connection with a web server and transmit HTML pages to the
client web browser.
Wireless Access Point Router with 4-Port Switch
• POP3 (Post Office Protocol 3) A standard mail server commonly used on
the Internet. It provides a message store that holds incoming e-mail until
users log on and download it. POP3 is a simple system with little selectivity.
All pending messages and attachments are downloaded at the same time.
POP3 uses the SMTP messaging protocol.
• NNTP (Network News Transfer Protocol) The protocol used to connect to
Usenet groups on the Internet. Usenet newsreaders support the NNTP protocol.
• SNMP (Simple Network Management Protocol) A widely used network
monitoring and control protocol. Data is passed from SNMP agents, which
are hardware and/or software processes reporting activity in each network
device (hub, router, etc.) to the workstation console used to oversee the network. The agents return information contained in a MIB (Management
Information Base), which is a data structure that defines what is obtainable
from the device and what can be controlled (turned off, on, etc.).
You must check the Enable box to enable the applications you have defined.
To add a server using UPnP Forwarding:
1. Enter the name of the application in the appropriate Application Name
field.
2. Next to the name of the application, enter the number of the external port
used by the server in the Ext. Port column. Check with the Internet application software documentation for more information.

Important: Dynamic Routing is an Advanced Function. No
changes should be made to this tab without a thorough understanding of networking concepts.
From the Dynamic
Routing tab, shown
in Figure 5-19, you
can automatically

Figure 5-19
protocol regularly broadcasts routing information to other routers on the network. To set up Dynamic Routing:
1. Choose the correct Working Mode. Gateway Mode should be used if the
Router is hosting your network’s connection to the Internet. Router Mode
should be selected if the Router exists on a network with other routers.

Advanced Tab: Static Routing
Important: Static Routing is an Advanced Function. No
changes should be made to this tab without a thorough understanding of networking concepts.
Wireless Access Point Router with 4-Port Switch
2. Enter the following data to create a new static route:
Destination LAN IP. The Destination LAN IP is the address of the remote
network or host to which you want to assign a static route. Enter the IP
address of the host for which you wish to create a static route here. If you
are building a route to an entire network, be sure that the host portion of the
IP address is set to zero. For example, the Router’s standard IP address is
192.168.1.1. Based on this address, the address of the network to which the
Router is connected is 192.168.1. You would enter the IP address
192.168.1.0 if you wanted to route to the entire network, rather than just to
the Router.
Subnet Mask. The Subnet Mask indicates which portion of an IP address
is the network portion and which portion is the host portion. If, for instance,
you use a Subnet Mask of 255.255.255.0 with the example shown above for
Destination LAN IP, then this would indicate that the first three numbers of
an network IP address identifies this particular network, while the last
number in the network address (from 1 to 254) would identify the specific
host.
Gateway IP. This IP address should be the IP address of the gateway
device that allows for contact between the Router and the remote network
or host.
Hop Count. This value gives the number of nodes that a data packet passes through before reaching its destination. A node is any device
on the network, such as switches, PCs, etc.
Figure 5-20
If the Router is connected to more than one network, it may be necessary to set
up a static route between them. This is set on the Static Routing tab, as shown
in Figure 5-20. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. Click the Show
Routing Table button to view the current static routing configuration.
To create a static route entry:
Interface. This interface tells you whether your network is on the internal
LAN or the WAN, or the external Internet. If you’re connecting to a subnetwork, select LAN. If you’re connecting to another network through the

Some ISPs require
that you register the
Figure 5-22
MAC address of your
network card/adapter, which was connected to your cable or DSL modem during
installation. Therefore, in order to connect the Router to your cable or DSL
modem in place of the PC (network card or adapter), you must change the Router
MAC to duplicate (or clone) your network card/adapter MAC. You can find your
adapter's MAC address by doing the following:
•
Whereas Port Range Forwarding can only forward a maximum of ten port
ranges, DMZ hosting forwards all the ports at the same time to one PC.
Before using this feature, the DHCP function on the PC whose port is being
exposed must be disabled and have a new static IP address assigned because its
IP address may change when using the DMZ function.
To expose one PC, enter the computer’s IP address. To get the IP address of a

Important: Wireless is an Advanced Function. No changes
should be made to this tab without a thorough understanding
of networking concepts.
•
Fragmentation Threshold. This value indicates how much of the Router’s
resources are devoted to recovering packet errors. The value should remain
at its default setting of 2,346. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely
decrease overall network performance. Only minor modifications of this
value are recommended.
Before making any
changes
to
the
Wireless tab, shown
in Figure 5-23,
please check the
wireless settings for
all your wireless
PCs,
as
these
changes will alter the
Router’s effectiveness. In most cases,
these settings do not
need to be changed.
•
DTIM Interval. This value indicates the interval of the Delivery Traffic
Indication Message (DTIM). A DTIM field is a countdown field informing
clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value.
Clients for the Router hear the beacons and awaken to receive the broadcast
and multicast messages.
•
Basic Rates. The basic transfer rates should be set depending on the speed
of your wireless network. You must select 1-2 (Mbps) if you have older
802.11 compliant equipment on your network, such as wireless adapters
that support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does not
limit the basic transfer rates of faster adapters.
•
TX Rates. Select all the supported rates at which an access point will communicate with a client.
•
Preamble Type. The preamble defines the length of the CRC block for
communication between the Router and the roaming Network Card. (High
network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type and click the Apply button to set it.
•
Authentication Type. You may choose between Open System, Shared
Key, and Both. The Authentication Type default is set to Open System, in
which the sender and the recipient do NOT share a secret key. Each party
generates its own key-pair and asks the receiver to accept the randomlygenerated key. Once accepted, this key is used for a short time only. Then
a new key is generated and agreed upon. Shared Key is when both the
sender and the recipient share a secret key.
•
Antenna Selection. This selection is for choosing which antenna transmits
data. By default, the Diversity Antenna selection, used to increase reception, is chosen.

Appendix A: Troubleshooting
Common Problems and Solutions
This appendix consists of two parts: “Common Problems and Solutions” and
“Frequently Asked Questions.” Provided are possible solutions to problems
regarding the installation and operation of the Router. If your situation is described
here, the problem should be solved by applying the corresponding solution. If you
can’t find an answer here, check the Linksys website at www.linksys.com.
1. I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of 192.168.1.100 to
192.168.1.150 using the DHCP server on the Router. To set a static IP address, you
can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to
192.168.1.254. Each PC or network device that uses TCP/IP must have a unique
address to identify itself in a network. If the IP address is not unique to a network,
Windows will generate an IP conflict error message. You can assign a static IP
address to a PC by performing the following steps:
Figure 5-23
Click the Wireless MAC Entry drop-down menu to select a range of
entries for your network. From within this range, select the entry for which
you’d like to manage access. Verify that the appropriate MAC Address is
entered into the MAC Address field. Click the Filter checkbox beside that
MAC Address. Now, this user will be prevented from accessing the Router.
All other users will have access. To allow only that user and deny access to
all others, leave Filter unchecked.
Click the Apply button to set these changes or Undo if you do not wish
these changes to go into effect.
When finished with the Wireless Tab, click the Apply button to save the settings. Otherwise, click the Cancel button to undo changes made on this screen.

static IP address.”
D. Refer to “Problem #10: I need to remove the proxy settings or the dial-up
pop-up window (for PPPoE users).”
Check the Linksys website for more information at www.linksys.com.
5. I can’t get my Virtual Private Network (VPN) working through the Router.
Access the Router’s web interface by going to http://192.168.1.1 or the IP
address of the Router, and go to the Advanced => Filter tab. Make sure you
have IPsec pass-through and/or PPTP pass-through enabled.
A. Access the Router’s web-based utility by going to http://192.168.1.1 or the
IP address of the Router. Go to the Advanced => Forwarding tab.
B. Enter any name you want to use for the Customized Application.
C. Enter the Ext. Port range of the service you are using. For example, if you
have a web server, you would enter the range 80 to 80.
D. Check the protocol you will be using, TCP and/or UDP.
E. Enter the IP address of the PC or network device that you want the port
server to go to. For example, if the web server’s Ethernet adapter IP address
is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet
Adapter” for details on getting an IP address.
F. Check the Enable option for the port services you want to use. Consider the
example below:
VPNs that use IPSec with the ESP (Encapsulation Security Payload known as
protocol 50) authentication will work fine. At least one IPSec session will work
through the Router; however, simultaneous IPSec sessions may be possible,
depending on the specifics of your VPNs.
VPNs that use IPSec and AH (Authentication Header known as protocol 51)
are incompatible with the Router. AH has limitations due to occasional incompatibility with the NAT standard.
Change the IP address for the Router to another subnet to avoid a conflict
between the VPN IP address and your local IP address. For example, if your
VPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254)
and your local LAN IP address is 192.168.1.X (X is the same number used in
the VPN IP address), the Router will have difficulties routing information to
the right location. If you change the Router’s IP address to 192.168.2.1, that
should solve the problem. Change the Router’s IP address through the Setup tab
of the web interface. If you assigned a static IP address to any computer or network device on the network, you need to change its IP address accordingly to
192.168.2.Y (Y being any number from 1 to 254). Note that each IP address
must be unique within the network.
59

6. I need to set up a server behind my Router.
To use a server like a web, ftp, or mail server, you need to know the respective
port numbers they are using. For example, port 80 (HTTP) is used for web;
port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110
(POP3 incoming) are used for the mail server. You can get more information
by viewing the documentation provided with the server you installed. Follow
these steps to set up port forwarding through the Router’s web-based utility. We
will be setting up web, ftp, and mail servers.

7. I need to set up online game hosting or use other Internet applications.
If you want to play online games or use Internet applications, most will work
without doing any port forwarding or DMZ hosting. There may be cases when
you want to host an online game or Internet application. This would require
you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way
to get the information on what port services to use is to go to the website of the
online game or application you want to use. Follow these steps to set up online
game hosting or use a certain Internet application:
A. Access the Router’s web interface by going to http://192.168.1.1 or the IP
address of the Router. Go to the Advanced => Forwarding tab.
B. Enter any name you want to use for the Customized Application.
C. Enter the Ext. Port range of the service you are using. For example, if you
want to host Unreal Tournament (UT), you would enter the range 7777 to
27900.
D. Check the protocol you will be using, TCP and/or UDP.
E. Enter the IP address of the PC or network device that you want the port
server to go to. For example, if the web server’s Ethernet adapter IP address
is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet
Adapter” for details on getting an IP address.
F. Check the Enable option for the port services you want to use. Consider the

8. I can’t get the Internet game, server, or application to work.
If you are having difficulties getting any Internet game, server, or application
to function properly, consider exposing one PC to the Internet using
DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to
use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In
other words, data that enters the Router will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Router will send the data to whichever PC or network device
you set for DMZ hosting.) Follow these steps to set DMZ hosting:
A. Access the Router’s web-based utility by going to http://192.168.1.1 or the
IP address of the Router. Go to the Advanced => Forwarding tab.
B. Disable or remove the entries you have entered for forwarding. Keep this
information in case you want to use it at a later time.
C. Click the DMZ Host tab.
D. Enter the Ethernet adapter’s IP address of the computer you want exposed
to the Internet. This will bypass the NAT firewall for that computer. Please
refer to “Appendix D: Finding the MAC Address and IP Address for Your
Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the Apply button.
9. I forgot my password, or the password prompt always appears when saving settings to the Router.
Reset the Router to factory default by pressing the Reset button for 30 seconds
and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps:
A. Access the Router’s web interface by going to http://192.168.1.1 or the IP
address of the Router. Enter the default password admin, and click the
Password tab.
B. Enter a different password in the Router Password field, and enter the
same password in the second field to confirm the password.
C. Click the Apply button.

Frequently Asked Questions
What is the maximum number of IP addresses that the Router will support? The
Router will support up to 253 IP addresses.
Is IPSec Pass-Through supported by the Router? Yes, it is a built-in feature that
the Router automatically enables.
Where is the Router installed on the network? In a typical environment, the
Router is installed between the cable/DSL modem and the LAN. Plug the
Router into the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk? No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from
one node to another, and AppleTalk, a communications protocol used on
Apple and Macintosh networks, can be used for LAN to LAN connections,
but those protocols cannot connect from WAN to LAN.
Does the WAN connection of the Router support 100 Mbps Ethernet? Because of
the speed limitations of broadband Internet connections, the Router’s current
hardware design supports 10 Mbps Ethernet on its WAN port. It does, of
course, support 100 Mbps over the auto-sensing Fast Ethernet 10/100 switch
on the LAN side of the Router.
What is Network Address Translation and what is it used for? Network Address
Translation (NAT) translates multiple IP addresses on the private LAN to one
public address that is sent out to the Internet. This adds a level of security
since the address of a PC connected to the private LAN is never transmitted
on the Internet. Furthermore, NAT allows the Router to be used with low cost
Internet accounts, such as DSL or cable modems, when only one TCP/IP
address is provided by the ISP. The user may have many private addresses
behind this single address provided by the ISP.
Does the Router support any operating system other than Windows 95, Windows
98, Windows 2000, Windows NT, or Windows XP? Yes, but Linksys does not, at
this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.
67
Does the Router support ICQ send file? Yes, with the following fix: click ICQ
menu -> preference -> connections tab->, and check I am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the Router.
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do
I need to do? If you have a dedicated Unreal Tournament server running, you
need to create a static IP for each of the LAN computers and forward ports
7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You
can also use a port forwarding range of 7777 ~ 27900. If you want to use the
UT Server Admin, forward another port (8080 usually works well but is used
for remote admin. You may have to disable this.), and then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to
match the mapped port above) and ServerName to the IP assigned to the
Router from your ISP.
Can multiple gamers on the LAN get on one game server and play simultaneously
with just one public IP address? It depends on which network game or what
kind of game server you are using. For example, Unreal Tournament supports
multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Router? The default client
port for Half-Life is 27005. The computers on your LAN need to have
“+clientport 2700x” added to the HL shortcut command line; the x would be
6, 7, 8, and on up. This lets multiple computers connect to the same server.
One problem: Version 1.0.1.6 won’t let multiple computers with the same CD
key connect at the same time, even if on the same LAN (not a problem with
1.0.1.3). As far as hosting games, the HL server does not need to be in the
DMZ. Just forward port 27015 to the local IP address of the server computer.
How can I block corrupted FTP downloads? If you are experiencing corrupted
files when you download a file with your FTP client, try using another FTP
program.
The web page hangs; downloads are corrupt, or nothing but junk characters are
being displayed on the screen. What do I need to do? Force your Ethernet
adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate”
feature of your Ethernet adapter as a temporary measure. (Please look at the
Network Control Panel in your Ethernet adapter’s Advanced Properties tab.)
68
Instant WirelessTM Series
Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.com for more information.
If all else fails in the installation, what can I do? Reset the Router by holding
down the reset button until the Diag LED fully turns on and off. Reset your
cable or DSL modem by powering the unit off and then on. Obtain and flash
the latest firmware release that is readily available on the Linksys website,
www.linksys.com.
How will I be notified of new Router firmware upgrades? All Linksys firmware
upgrades are posted on the Linksys website at www.linksys.com, where they
can be downloaded for free. The Router’s firmware can be upgraded with
TFTP programs. If the Router’s Internet connection is working well, there is
no need to download a newer firmware version, unless that version contains
new features that you would like to use. Downloading a more current version
of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability.
Will the Router function in a Macintosh environment? Yes, but the Router’s setup
pages are accessible only through Internet Explorer 4.0 or Netscape
Navigator 4.0 or higher for Macintosh.
I am not able to get the web configuration screen for the Router. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g.,
Netscape Navigator or Internet Explorer. Or remove the dial-up settings on
your browser. Check with your browser documentation, and make sure that
your browser is set to connect directly and that any dial-up is disabled. Make
sure that your browser is set to connect directly and that any dial-up is dis abled. For Internet Explorer, click Tools , Internet Options, and then the
Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and
Proxy. Make sure that Netscape Navigator is set to Direct connection to the
Internet.
What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications require multiple
TCP/IP ports to be open. It is recommended that you set your computer with
a static IP if you want to use DMZ Hosting. To get the LAN IP address, see
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet
Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
69
Wireless Access Point Router with 4-Port Switch
Does the Router pass PPTP packets or actively route PPTP sessions? The Router
allows PPTP packets to pass through.
Is the Router cross-platform compatible? Any platform that supports Ethernet
and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded? Theoretically, the Router can
establish 520 sessions at the same time, but you can only forward 10 ranges
of ports.
Does the Router replace a modem? Is there a cable or DSL modem in the Router?
No, this version of the Router must work in conjunction with a cable or DSL
modem.
Which modems are compatible with the Router? The Router is compatible with
virtually any cable or DSL modem that supports Ethernet.
What are the advanced features of the Router? The Router’s advanced features
include IP Filtering, Port Range Forwarding, Dynamic Routing, Static
Routing, DMZ hosting, and MAC Address Cloning.
What is the maximum number of VPN sessions allowed by the Router?
The maximum number depends on many factors. At least one IPSec session
will work through the Router; however, simultaneous IPSec sessions may be
possible, depending on the specifics of your VPNs.
How big is the memory buffer on the Router? 1MB buffer and 512KB flash.
How can I check whether I have static or DHCP IP Addresses? Consult your ISP
to obtain this information.
How do I get mIRC to work with the Router? Under the Port Range Forwarding
tab, set port forwarding to 113 for the PC on which you are using mIRC.
Can the Router act as my DHCP Server? Yes. The Router has DHCP Server software built-in.
Can I run an application from a remote computer over the wireless network? This
will depend on whether or not the application is designed to be used over a
70
Instant WirelessTM Series
network. Consult the application’s documentation to determine if it supports
operation over a network.
What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards
subcommittee formulates the standard for the industry. The objective is to
enable wireless LAN hardware from different manufacturers to communicate.
What IEEE 802.11 features are supported? The product supports the following
IEEE 802.11 functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS).
Computers in a BSS must be configured with the same BSS ID.
What is SSID? An Infrastructure configuration could also support roaming
capability for mobile workers. More than one BSS can be configured as an
Extended Service Set (ESS). Users within an ESS could roam freely between
BSSs while maintaining a continuous connection to the wireless network stations and Access Points.
What is ISM band? The FCC and their counterparts outside of the U.S. have set
aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and
Medical) band. This presents a truly revolutionary opportunity to place convenient high speed wireless capabilities in the hands of users around the
globe.
What is Spread Spectrum? Spread Spectrum technology is a wideband radio
frequency technique developed by the military for use in reliable, secure, mis sion-critical communications systems. It is designed to trade off bandwidth
efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the tradeoff produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal
being broadcast. If a receiver is not tuned to the right frequency, a spreadspectrum signal looks like background noise. There are two main alternatives,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread
Spectrum (FHSS).
71
Wireless Access Point Router with 4-Port Switch
What is DSSS? What is FHSS? And what are their differences? Frequency
Hopping Spread Spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an
unintended receiver, FHSS appears to be short-duration impulse noise. Direct
Sequence Spread Spectrum (DSSS) generates a redundant bit pattern for each
bit to be transmitted. This bit pattern is called a chip (or chipping code). The
longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission,
statistical techniques embedded in the radio can recover the original data
without the need for retransmission. To an unintended receiver, DSSS appears
as low power wideband noise and is rejected (ignored) by most narrowband
receivers.
Would the information be intercepted while transmitting on air? WLAN features
two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, the WLAN series offers the encryption
function (WEP) to enhance security and access control. Users can set it up
depending upon their needs.
What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism
based on a 40/64 bit shared key algorithm, as described in the IEEE 802.11
standard.
What is a MAC Address? The Media Access Control (MAC) address is a unique
number assigned by the manufacturer to any Ethernet networking device,
such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent.
Unlike IP addresses, which can change every time a computer logs on to the
network, the MAC address of a device stays the same, making it a valuable
identifier for the network.

Appendix B: How to Ping Your ISP’s
E-mail and Web Addresses
Virtually all Internet addresses are configured with words or characters (i.e.,
www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet
addresses are assigned to IP addresses, which are the true addresses on the
Internet. For example, www.linksys.com is actually 216.23.162.142. Entering
that into your web browser will bring up at the Linksys home page every time.
IP and web addresses, however, can sometimes be long and hard to remember.
Because of this, certain ISPs will shorten their server addresses to single words
or codes on their users’ web browser or e-mail configurations. If your ISP’s email and web server addresses are configured with single words (“www,” “email,” “home,” “pop3,” etc.) rather than whole Internet Addresses or IP
Addresses, the Router may have problems sending or receiving mail and
accessing the Internet. This happens because the Router has not been configured by your ISP to accept their abbreviated server addresses.
The solution is to determine the true web addresses behind your ISP’s code
words. You can determine the IP and web addresses of your ISP’s servers by
“pinging” them.
Note: If you don’t have your ISP’s web and e-mail IP addresses, you must
either get them from your ISP or follow these steps prior to connecting the
Router to your network.
Step One: Pinging an IP Address
The first step to determining your ISP’s web and e-mail server address is to
ping its IP address.
1. Power on the computer and the cable or DSL modem, and restore the
network configuration set by your ISP if you have since changed it.
Wireless Access Point Router with 4-Port Switch
3. At the DOS command prompt, type “ping mail” (assuming that the location for which you’re trying to find an IP address is configured as “mail”).
Press Enter. Information such as the following data, taken from a ping of
Microsoft Network’s e-mail server, will be displayed.

Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
4. Write down the IP address returned by the ping command. (In the
example above: 24.53.32.4.) This IP address is the actual IP address of the
server “mail,” or any other word or value you have pinged.
Step Two: Pinging for a Web Address
While the IP address returned above would work as your e-mail server address,
it may not be permanent. IP addresses change all the time. Web addresses, however, usually don’t. Because of this, you’re likely to have fewer problems by
configuring your system with web addresses rather than IP addresses. Follow
the instructions below to find the web address assigned to the IP address you
just pinged.
1. At the DOS command prompt, type “ping -a 24.53.32.4,” where
24.53.32.4 is the IP address you just pinged. Information such as the following data will be displayed.
2. Click Start, then Run, and type “command.” This will bring up the DOS
window.

2. Write down the web address returned by the ping command (in the
example above: mail.msnv3.occa.home.com.). This web address is the web
address assigned to the IP address you just pinged. While the IP address of
“mail” could conceivably change, it is likely that this web address will not.
3. Replace your ISP’s abbreviated server address with this extended web
address in the corresponding Internet application (web browser, e-mail
application, etc.).
Once you have replaced the brief server address with the true server address,
the Router should have no problem accessing the Internet through that Internet
application.

Appendix C: Configuring Wireless
Security
Note: WEP encryption is an additional data security measure and not essential for router operation.
An acronym for Wired Equivalent Privacy, WEP is an encryption method used
to protect your wireless data communications. WEP uses a combination of 64bit or 128-bit keys to provide access control to your network and encryption
security for every data transmission. To decode a data transmission, each point
in a network must use an identical 64-bit or 128-bit key. Higher encryption levels mean higher levels of security, but due to the complexity of the encryption,
they may mean decreased network performance.
You may also have heard the term “40-bit” used in conjunction with WEP
encryption. This is simply another term for 64-bit WEP encryption. This level
of WEP encryption has been called 40-bit because it uses a 40-bit secret key
along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may
use either name. Linksys uses the term “64-bit” when referring to this level of
encryption.
Make sure your wireless network is functioning before attempting to configure
WEP encryption.
A 128-bit WEP encrypted wireless network will NOT communicate with a 64bit WEP encrypted wireless network. Therefore, make sure that all of your
wireless devices are using the same encryption level. All wireless devices complying with the 802.11b standard will support 64-bit WEP.
In addition to enabling WEP, Linksys also recommends the following security
implementations:
• Changing the SSID from the default “linksys”
• Changing the WEP key regularly
Note: In order for WEP Encryption to be enabled, wireless functions must
first be enabled. Select Enable under the Wireless section before proceeding.

The following steps will show you how to utilize WEP encryption
1. From the Web-based Utility’s Setup tab, select Mandatory under the WEP
section.
2. Press the WEP Key Setting button to set the WEP Encryption type and
level.
Wireless Access Point Router with 4-Port Switch
•
WEP (64Bit or 128B) Select the level of encryption from the drop-down
box. 128-bit WEP encryption is unique to Linksys and may conflict with
other vendors’ WEP encryption.
Note: In order to utilize WEP encryption, all points in your wireless
network must have WEP enabled and be set to the same Key Setting.
The WEP Encryption key is generated in one of two ways:
3. The screen displayed in Figure
C-1 may appear,
verifying that you
are enabling WEP
Encryption. Press
the OK button to
continue.
1. You may create an encryption key by using a Passphrase.
a. Enter a Passphrase, a user-defined password, into the Passphrase field.
The Passphrase can be a maximum of 31 letters, symbols, and numbers.
No spaces can be used.
Figure C-1
4. This will display the screen shown in Figure C-2. From this screen, you will
choose your WEP Encryption settings.
b. Click the Generate button to create a key. The key will be 10 digits if
you chose 64-bit encryption, or 26 digits if you chose 128-bit encryption.
This key will be used to encrypt and decrypt the data being sent between
the Router and your network’s wireless PCs.
The Key field may not display all digits. Using the mouse, click anywhere within the Key field. Move the cursor to the right to view the rest
of the Key. Make sure your write down the entire Key EXACTLY the
way it is displayed.
2. You may enter the encryption key manually.
Make a note of the Passphrase or Manual Key. You will need it for the other
wireless devices on the network, as the same WEP encryption key must be
entered in all wireless devices on the network.
Once you have chosen your key encryption method and entered either the
Passphrase or manual key, click the Apply button, and the encryption portion
of the setup is complete.
Note: In Windows XP, a 128-bit Key generated by the Router
will be called a "104 bits (26 digits)" key, and a 64-bit Key generated by the Router will be called a “40 bits (10 digits)” key.

Appendix F: Glossary
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.
Also, the smallest form of data.
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 wire.
Boot - To cause the computer to start executing instructions. Personal computers contain built-in instructions in a ROM chip that are automatically executed
on startup. These instructions search for the operating system, load it and pass
control to it.
Adapter - Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card is
the typical adapter that allows the PC or server to connect to the intranet and/or
Internet.
Broadband - A data-transmission scheme in which multiple signals share the
bandwidth of a medium. This allows the transmission of voice, data and video
signals over a single medium. Cable television uses broadband techniques to
deliver dozens of channels over one cable.
Ad-hoc Network - An ad-hoc network is a group of computers, each with a
wireless adapter, connected as an independent 802.11 wireless LAN. Ad-hoc
wireless computers operate on a peer-to-peer basis, communicating directly
with each other without the use of an access point. Ad-hoc mode is also
referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode.
Browser - A browser is an application program that provides a way to look at
and interact with all the information on the World Wide Web or PC. The word
"browser" seems to have originated prior to the Web as a generic term for user
interfaces that let you browse text files online.
10BaseT - An Ethernet standard that uses twisted wire pairs.
AppleTalk - An Apple Computer networking system that support Apple's proprietary local talk.
Auto-negotiate - To automatically determine the correct settings. The term is
often used with communications and networking. For example, Ethernet
10/100 cards, hubs and switches can determine the highest speed of the node
they are connected to and adjust their transmission rate accordingly.
Backbone - The part of a network that connects most of the systems and networks together and handles the most data.
Bandwidth - The transmission capacity of a given facility, in terms of how
much data the facility can transmit in a fixed amount of time; expressed in bits
per second (bps).
Beacon Interval - A beacon is a packet broadcast by the Access Point to keep
the network synchronized. A beacon includes the wireless LAN service area,
the AP address, the Broadcast destination addresses, a time stamp, Delivery
Traffic Indicator Maps, and the Traffic Indicator Message (TIM).
91
Wireless Access Point Router with 4-Port Switch
BSS (Basic Service Set) - An infrastructure network connecting wireless
devices to a wired network using a single access point.
Buffer - A buffer is a shared or assigned memory area used by hardware
devices or program processes that operate at different speeds or with different
sets of priorities. The buffer allows each device or process to operate without
being held up by the other. In order for a buffer to be effective, the size of the
buffer and the algorithms for moving data into and out of the buffer need to be
considered by the buffer designer. Like a cache, a buffer is a "midpoint holding
place" but exists not so much to accelerate the speed of an activity as to support the coordination of separate activities.
Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet. Once connected, cable modem
users have a continuous connection to the Internet. Cable modems feature
asymmetric transfer rates: around 36 Mbps downstream (from the Internet to
the computer), and from 200 Kbps to 2 Mbps upstream (from the computer to
the Internet).
CAT 5 - ANSI/EIA (American National Standards Institute/Electronic
Industries Association) Standard 568 is one of several standards that specify
"categories" (the singular is commonly referred to as "CAT") of twisted pair
92
Instant WirelessTM Series
cabling systems (wires, junctions, and connectors) in terms of the data rates
that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and
is usually utilized for 100BaseTX networks.
cially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.
CAT 5e - The additional cabling performance parameters of return loss and farend crosstalk (FEXT) specified for 1000BASE-T and not specified for
10BASE-T and 100BASE-TX are related to differences in the signaling implementation. 10BASE-T and 100BASE-TX signaling is unidirectional-signals
are transmitted in one direction on a single wire pair. In contrast, Gigabit
Ethernet is bi-directional-signals are transmitted simultaneously in both directions on the same wire pair; that is, both the transmit and receive pair occupy
the same wire pair.
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) - In local
area networking, this is the CSMA technique that combines slotted time-division multiplexing with carrier sense multiple access/collision detection
(CSMA/CD) to avoid having collisions occur a second time. This works best if
the time allocated is short compared to packet length and if the number of situations is small.
Data Packet - One frame in a packet-switched message. Most data communications is based on dividing the transmitted message into packets. For example,
an Ethernet packet can be from 64 to 1518 bytes in length.
DMZ (Demilitarized Zone) - Allows one IP address (or computer) to be
exposed to the Internet. Some applications require multiple TCP/IP ports to be
open. It is recommended that you set your computer with a static IP address if
you want to use DMZ Hosting.
DNS - The domain name system (DNS) is the way that Internet domain name
are located and translated into Internet Protocol (IP) addresses. A domain name
is a meaningful and easy-to-remember "handle" for an Internet address.
Domain - A subnetwork comprised of a group of clients and servers under the
control of one security database. Dividing LANs into domains improves performance and security.
Download - To receive a file transmitted over a network. In a communications
session, download means receive, upload means transmit.
Default Gateway - The routing device used to forward all traffic that is not
addressed to a station within the local subnet.
DSL (Digital Subscriber Line) - A technology that dramatically increases the
digital capacity of ordinary telephone lines into the home or office and, by
employing unused bandwidth, still allows for normal phone usage. DSL provides "always-on" operation, eliminating the need to dial in to the service.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators manage centrally and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet's set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and dis tribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit
pattern for all data transmitted. This bit pattern is called a chip (or chipping
code). Even if one or more bits in the chip are damaged during transmission,
statistical techniques embedded in the receiver can recover the original data
without the need for retransmission. To an unintended receiver, DSSS appears
as low power wideband noise and is rejected (ignored) by most narrowband
receivers. However, to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference
is inherently rejected (ignored).
DHCP uses the concept of a "lease" or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It's espe93
Wireless Access Point Router with 4-Port Switch
DTIM (Delivery Traffic Indication Message) - A DTIM field is a countdown
field informing clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for
94
Instant WirelessTM Series
associated clients, it sends the next DTIM with a DTIM Interval value. AP
Clients hear the beacons and awaken to receive the broadcast and multicast
messages.
Dynamic IP Address - An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
serve multiple users, such as servers and printers, are usually assigned static IP
addresses.
Dynamic Routing - The ability for a router to forward data via a different route
based on the current conditions of the communications circuits. For example,
it can adjust for overloaded traffic or failing lines and is much more flexible
than static routing, which uses a fixed forwarding path.
Encryption - A security method that applies a specific algorithm to data in
order to alter the data's appearance and prevent other devices from reading the
information.
ESS (Extended Service Set) - A set of more than two or more BSSs (multiple
access points) forming a single network.
Ethernet - IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet
CSMA/CD network access method.
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes
(hops) the carrier frequency of a conventional carrier several times per second
according to a pseudo-random set of channels. Because a fixed frequency is not
used, and only the transmitter and receiver know the hop patterns, interception
of FHSS is extremely difficult.
Finger - A UNIX command widely used on the Internet to find out information about a particular user, such as telephone number, whether currently
logged on or the last time logged on. The person being "fingered" must have
placed his or her profile on the system. Fingering requires entering the full
user@domain address.
Wireless Access Point Router with 4-Port Switch
Firewall - A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a network from users from other networks.
(The term also implies the security policy that is used with the programs.) An
enterprise with an intranet that allows its workers access to the wider Internet
installs a firewall to prevent outsiders from accessing its own private data
resources and for controlling what outside resources to which its own users
have access.
Basically, a firewall, working closely with a router, examines each network
packet to determine whether to forward it toward its destination.
Firmware - Code that is written onto read-only memory (ROM) or programmable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
Fragmentation - Breaking a packet into smaller units when transmitting over
a network medium that cannot support the original size of the packet.
FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IP
network (Internet, UNIX, etc.). For example, after developing the HTML pages
for a Web site on a local machine, they are typically uploaded to the Web server using FTP.
FTP includes functions to log onto the network, list directories and copy files.
It can also convert between the ASCII and EBCDIC character codes. FTP operations can be performed by typing commands at a command prompt or via an
FTP utility running under a graphical interface such as Windows. FTP transfers
can also be initiated from within a Web browser by entering the URL preceded
with ftp://.
Unlike e-mail programs in which graphics and program files have to be
"attached," FTP is designed to handle binary files directly and does not add the
overhead of encoding and decoding the data.
Full Duplex - The ability of a device or line to transmit data simultaneously in
both directions.
Gateway - A device that interconnects networks with different, incompatible
communications protocols.
Half Duplex - Data transmission that can occur in two directions over a single
line, but only one direction at a time.
95
96

Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to dis tinguish the "box" and the electronic circuitry and components of a computer
from the program you put in it to make it do things. The program came to be
known as the software.
Hop - The link between two network nodes.
HTTP (HyperText Transport Protocol) - The communications protocol used
to connect to servers on the World Wide Web. Its primary function is to establish a connection with a Web server and transmit HTML pages to the client
browser.
Hub - The device that serves as the central location for attaching wires from
workstations. Can be passive, where there is no amplification of the signals; or
active, where the hubs are used like repeaters to provide an extension of the
cable that connects to a workstation.
ICQ - A conferencing program for the Internet that provides interactive chat,
e-mail and file transfer and can alert you when someone on your predefined list
has also come online.
IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE
describes itself as "the world's largest technical professional society, promoting
the development and application of electrotechnology and allied sciences for
the benefit of humanity, the advancement of the profession, and the well-being
of our members."
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.
Infrastructure Network - An infrastructure network is a group of computers
or other devices, each with a wireless adapter, connected as an 802.11 wireless
LAN. In infrastructure mode, the wireless devices communicate with each
other and to a wired network by first going through an access point. An infrastructure wireless network connected to a wired network is referred to as a
Basic Service Set (BSS). A set of two or more BSS in a single network is
referred to as an Extended Service Set (ESS). Infrastructure mode is useful at
a corporation scale, or when it is necessary to connect the wired and wireless
networks.
97
Wireless Access Point Router with 4-Port Switch
IP Address - In the most widely installed level of the Internet Protocol
(Internet Protocol) today, an IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packet across the
Internet. When you request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address in the message (actually, in
each of the packets if more than one is required) and sends it to the IP address
that is obtained by looking up the domain name in the Uniform Resource
Locator you requested or in the e-mail address you're sending a note to. At the
other end, the recipient can see the IP address of the Web page requestor or the
e-mail sender and can respond by sending another message using the IP address
it received.
IPCONFIG - A Windows NT or 2000 utility that provides for querying, defining and managing IP addresses within a network. A commonly used utility for
configuring networks with static IP addresses.
IPSec (Internet Protocol Security) - A suite of protocols used to implement
secure exchange of packets at the IP layer. IPSec supports two basic modes:
Transport and Tunnel. Transport encrypts the payload of each packet, leaving
the header untouched, while Tunnel mode encrypts both the header and the payload and is therefore more secure. IPSec must be supported on both transmitter and receiver and must share a public key. Tunnel mode is widely deployed
in VPNs (Virtual Private Networks).
IPX (Internetwork Packet EXchange) - A NetWare communications protocol
used to route messages from one node to another. IPX packets include network
addresses and can be routed from one network to another.
ISM band - The FCC and their counterparts outside of the U.S. have set aside
bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical)
band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as Web site
building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
98
Instant WirelessTM Series
MAC (Media Access Control) Address - A unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter,
that allows the network to identify it at the hardware level.
Plug-and-Play - The ability of a computer system to configure expansion
boards and other devices automatically without requiring the user to turn off
the system during installation.
Mbps (MegaBits Per Second) - One million bits per second; unit of measurement for data transmission.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems and
printers.
MIB (Management Information Base) - A set of database objects. This set contains information about a specific device for utilizing SNMP.
mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining and leaving channels.
Multicasting - Sending data to a group of nodes instead of a single destination.
NAT (Network Address Translation) - The translation of an Internet Protocol
address (IP address) used within one network to a different IP address known
within another network. One network is designated the inside network and the
other is the outside.
Network - A system that transmits any combination of voice, video and/or data
between users.
NNTP (Network News Transfer Protocol) - The protocol used to connect to
Usenet groups on the Internet. Usenet newsreaders support the NNTP protocol.
Node - A network junction or connection point, typically a computer or work
station.
Packet - A unit of data routed between an origin and a destination in a network.
Passphrase - Used much like a password, a passphrase simplifies the WEP
encryption process by automatically generating the WEP encryption keys for
Linksys products.
PC Card - A credit-card sized removable module that contains memory, I/O,
or a hard disk.
Ping (Packet INternet Groper) - An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response.
99
Wireless Access Point Router with 4-Port Switch
PPPoE (Point to Point Protocol over Ethernet) - PPPoE is a method for the
encapsulation of PPP packets over Ethernet frames from the user to the ISP
over the Internet. One reason PPPoE is preferred by ISPs is because it provides
authentication (username and password) in addition to data transport. A PPPoE
session can be initiated by either a client application residing on a PC, or by
client firmware residing on a modem or router.
PPTP (Point-to-Point Tunneling Protocol) - A protocol (set of communication
rules) that allows corporations to extend their own corporate network through
private "tunnels" over the public Internet. Effectively, a corporation uses a
wide-area network as a single large local area network. A company no longer
needs to lease its own lines for wide-area communication but can securely use
the public networks. This kind of interconnection is known as a virtual private
network.
RIP (Routing Information Protocol) - A simple routing protocol that is part of
the TCP/IP protocol suite. It determines a route based on the smallest hop count
between source and destination. RIP is a distance vector protocol that routinely broadcasts routing information to its neighboring routers.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Roaming - In an infrastructure mode wireless network, this refers to the ability to move out of one access point's range and into another and transparently
reassociate and reauthenticate to the new access point. This reassociation and
reauthentication should occur without user intervention and ideally without
interruption to network connectivity. A typical scenario would be a location
with multiple access points, where users can physically relocate from one area
to another and easily maintain connectivity.
100
Instant WirelessTM Series
Router - Protocol-dependent device that connects subnetworks together.
Routers are useful in breaking down a very large network into smaller subnetworks; they introduce longer delays and typically have much lower throughput
rates than bridges.
RTS (Request To Send) - An RS-232 signal sent from the transmitting station
to the receiving station requesting permission to transmit.
Server - Any computer whose function in a network is to provide user access
to files, printing, communications, and other services.
SMTP (Simple Mail Transfer Protocol) - The standard e-mail protocol on the
Internet. It is a TCP/IP protocol that defines the message format and the mes sage transfer agent (MTA), which stores and forwards the mail.
SNMP (Simple Network Management Protocol) - A widely used network
monitoring and control protocol. Data is passed from SNMP agents, which are
hardware and/or software processes reporting activity in each network device
(hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return information contained in a MIB (Management
Information Base), which is a data structure that defines what is obtainable
from the device and what can be controlled (turned off, on, etc.).
Software - Instructions for the computer. A series of instructions that performs
a particular task is called a "program." The two major categories of software are
"system software" and "application software." System software is made up of
control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the
user.
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.
Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency
for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade off produces
a signal that is, in effect, louder and thus easier to detect, provided that the
receiver knows the parameters of the spread-spectrum signal being broadcast.
101
Wireless Access Point Router with 4-Port Switch
If a receiver is not tuned to the right frequency, a spread-spectrum signal looks
like background noise. There are two main alternatives, Direct Sequence
Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
SPI (Stateful Packet Inspection) - A firewall technology that monitors the state
of the transaction so that it can verify that the destination of an inbound packet matches the source of a previous outbound request. It examines not just the
headers of the packet, but also the contents, to determine more about the packet than just its source and destination information. It is called "stateful" because
verifies that the stated destination computer has previously requested the current communication. In this way, it verifies that all communications are initiated by the recipient computer and are taking place only with sources that are
known and trusted from previous interactions. In addition to being a more rigorous inspection, stateful packet inspection closes off ports until connection to
the specific port is requested. This allows an added layer of protection from the
threat of port scanning.
SSID (Service Set IDentifier) - A unique name shared among all points in a
wireless network. The SSID must be identical for each point in the wireless network and is case-sensitive.
Static IP Address - A permanent IP address that is assigned to a node in an IP
or a TCP/IP network.
Static Routing - Forwarding data in a network via a fixed path. Static routing
cannot adjust to changing line conditions as can dynamic routing.
Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
Switch - 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical circuit.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the IP (Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for effi-
102
Instant WirelessTM Series
cient delivery over the network. TCP is known as a "connection oriented" protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or set of protocols for communications over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of
protocols and not only TCP and IP.
Telnet - A terminal emulation protocol commonly used on the Internet and
TCP/IP-based networks. It allows a user at a terminal or computer to log onto
a remote device and run a program.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol
that has no directory or password capability.
Throughput - The amount of data moved successfully from one place to
another in a given time period.
TX Rate - Transmission Rate.
UDP (User Datagram Protocol) - A method (protocol) used along with the IP
(Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. UDP is known as a "connection-less" protocol
due to NOT requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet (as opposed to TCP).
Wireless Access Point Router with 4-Port Switch
UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
VPN (Virtual Private Network) - A technique that allows two or more LANs to
be extended over public communication channels by creating private communication subchannels (tunnels). Effectively, these LANs can use a WAN as a
single large "virtually private" LAN. This removes the need to use leased lines
for WAN communications through secure use of a publicly available WAN
(such as the Internet). Examples of VPN technology are: PPTP (Point to Point
Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol), and IPSec (Internet
Protocol Security).
WAN (Wide Area Network)- A communications network that covers a relatively large geographic area, consisting of two or more LANs. Broadband
communication over the WAN is often through public networks such as the
telephone (DSL) or cable systems, or through leased lines or satellites. In its
most basic definition, the Internet could be considered a WAN.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.
WINIPCFG - Configuration utility based on the Win32 API for querying,
defining and managing IP addresses within a network. A commonly used utility for configuring networks with static IP addresses.
Upgrade - To replace existing software or firmware with a newer version.
Upload - To transmit a file over a network. In a communications session,
upload means transmit, download means receive.
URL (Uniform Resource Locator) - The address that defines the route to a file
on the Web or any other Internet facility. URLs are typed into the browser to
access Web pages, and URLs are embedded within the pages themselves to provide the hypertext links to other pages.
