Setting up your wireless router
• Smurf Attack
• Fragment flooding
• TCP Null Scan
The firewall also masks common ports that are frequently used to attack networks. These
ports appear to be Stealth, meaning that for all intents and purposes, they do not exist to a
would-be hacker. You can turn the firewall function off if needed, however, it is
recommended that you leave the firewall enabled. Disabling the firewall protection will not
leave your network completely vulnerable to hacker attacks, but it is recommended that you
leave the firewall enabled.
Configuring Internal Forwarding Settings
The Virtual Servers function lets you route external (Internet) calls for services such as a Web
server (port 80), FTP server (Port 21), or other applications through your router to your
internal network. Since your internal computers are protected by a firewall, computers
outside your network (over the Internet) cannot get to them because they cannot be seen.
You will need to contact the application vendor to find out which port settings you need.
To enter settings into the virtual server:
1 Open the Virtual Servers page, then enter the IP address in the space provided for the
internal (server) machine, and the port(s) required to pass.
2 Select the port type (TCP or UDP), check the Enable box, then click Apply Changes.
Each inbound port entry has two fields with five characters maximum per field that
allows a start and end port range, for example, [xxxxx]-[xxxxx]. For each entry, you
can enter a single port value by filling in the two fields with the same value (e.g.
[7500]-[7500]) or a wide range of ports (for example [7500]-[9000]). If you need
multiple single port values or a combination of ranges and a single value, you must
use multiple entries up to the maximum of 20 entries (for example, 1. [7500]-[7500],
2. [8023]-[8023], 3. [9000]-[9000]). You can only pass one port per internal IP

address. Opening ports in your firewall can pose a security risk. You can enable and
disable settings very quickly. It is recommended that you disable the settings when
you are not using a specific application.
Setting Client IP Filters
The router can be configured to restrict access to the Internet, e-mail, or other network
services at specific days and times. Restriction can be set for a single computer, a range of
computers, or multiple computers.
To restrict Internet access to a single computer:
1 Open the Firewall > Client IP filters page, then enter the IP address of the computer you
wish to restrict access to in the IP fields.
2 Enter 80 in both the port fields, select Both, then select Block. You can also select
Always to block access all of the time.
3 Select the day to start on top, the time to start on top, the day to end on the bottom,
and the time to stop on the bottom.
4 Select Enable, then click Apply Changes. The computer at the IP address you
specified will now be blocked from Internet access at the times you specified. Be sure
you have selected the correct time zone under Utilities> System Settings> Time
Zone.
Setting MAC Address Filtering
The MAC address filter is a powerful security feature that allows you to specify which
computers are allowed on the network. Any computer attempting to access the network that
is not specified in the filter list will be denied access. When you enable this feature, you must
enter the MAC address of each client (computer) on your network to allow network access to
each.
36
Setting up your wireless router
To set MAC Address Filtering:
1 Open the Firewall > MAC Address filters page, then click Enable MAC Address
Filtering.
2 Enter the MAC address of each computer on your network by clicking in the space
provided and entering the MAC address of the computer you want to add to the list.
3 Click Add, then click Apply Changes to save the settings. You can have a
MAC-address-filtering list of up to 32 computers.
Note: You will not be able to delete the MAC address of the computer you are using to access
the router's administrative functions (the computer you are using now).
Enabling the Demilitarized Zone (DMZ)
The DMZ feature lets you specify one computer on your network to be placed outside of the
firewall. This may be necessary if the firewall is causing problems with an application such as
a game or video conferencing application. Use this feature on a temporary basis. The
computer in the DMZ is NOT protected from hacker attacks. If your ISP subscription provides
you with additional public (WAN) IP addresses, additional computers can be placed outside
the firewall provided each computer uses a different public (WAN) IP.
To set up a DMZ for a computer:
• Open the Firewall > DMZ page and enter the last digits of the computer’s IP address in
the IP field, click Enable, then click Apply Changes for the change to take effect.
WAN Ping Blocking
Computer hackers use what is known as pinging to find potential victims on the Internet. By
pinging a specific IP address and receiving a response from the IP address, a hacker can
determine that something of interest might be there. The router can be set up so it will not
respond to an ICMP ping from the outside. This heightens the level of security of your router.
To turn off the ping response
• Open the Firewall > WAN Ping Blocking page and select Block ICMP Ping, then click
Apply Changes. The router will not respond to an ICMP ping.

42
Setting up your wireless router
Changing system settings
The System Settings page is where you can enter a new administrator password, set the time
zone, enable remote management, and turn on and off the NAT function of the router.
Setting or changing the Administrator Password
The router ships with NO password entered. If you wish to add a password for greater
security, you can set a password here. Write down your password and keep it in a safe place,
as you will need it if you need to log into the router in the future. It is also recommended that
you set a password if you plan to use the remote management feature of your router.
Changing the Login Time-Out Setting
The login time-out option allows you to set the period of time that you can be logged into
the router's Web-Based Advanced User Interface. The timer starts when there has been no
activity. For example, you have made some changes in the Web-Based Advanced User
Interface, then left your computer alone without clicking “Logout”. Assuming the time-out is
set to 10 minutes, then 10 minutes after you leave, the login session will expire. You will have
to log into the router again to make any more changes. The login time-out option is for
security purposes and the default is set to 10 minutes.
Note: Only one computer can be logged into the router's Web-Based Advanced User Interface
at one time.
Setting the time and time zone
The router keeps time by connecting to a Simple Network Time Protocol (SNTP) server. This
allows the router to synchronize the system clock to the global Internet. The synchronized
clock in the router is used to record the security log and control client filtering. Select the
time zone that you reside in. If you reside in an area that observes daylight saving, then place
a check mark in the box next to Automatically Adjust Daylight Saving. The system clock
may not update immediately. Allow at least 15 minutes for the router to contact the time
servers on the Internet and get a response. You cannot set the clock yourself.
Setting up your wireless router
43
Enabling Remote Management
Before you enable this advanced feature of your router, MAKE SURE YOU HAVE SET THE
ADMINISTRATOR PASSWORD. Remote management allows you to make changes to your
router's settings from anywhere on the Internet. There are two methods of remotely
managing the router. The first is to allow access to the router from anywhere on the Internet
by selecting Any IP address can remotely manage the Router. By typing in your WAN IP
address from any computer on the Internet, you will be presented with a login screen where
you need to type in the password of your router. The second method is to allow a specific IP
address only to remotely manage the router. This is more secure, but less convenient. To use
this method, enter the IP address you know you will be accessing the router from in the space
provided and select Only this IP address can remotely manage the Router. Before you
enable this function, it is STRONGLY RECOMMENDED that you set your administrator
password. Leaving the password empty will potentially open your router to intrusion.
Enabling/Disabling Network Address Translation (NAT)
Note: This feature should only be modified by advanced users.
NAT is the method by which the router shares the single IP address assigned by your ISP with
the other computers on your network and is enabled by default. NAT should only be disabled
if your ISP assigns you multiple IP addresses or you need NAT disabled for an advanced
system configuration. If you have a single IP address and you turn NAT off, the computers on
your network will not be able to access the Internet. Other problems may also occur. Turning
off NAT will disable your firewall functions.
Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered by your router. It is a
technology that offers seamless operation of voice messaging, video messaging, games, and
other applications that are UPnP-compliant. Some applications require the router's firewall
to be configured in a specific way to operate properly. This usually requires opening TCP and
UDP ports. An application that is UPnP-compliant has the ability to communicate with the
router, basically “telling” the router which way it needs the firewall configured. The router
44
Setting up your wireless router
ships with the UPnP feature disabled. If you are using any applications that are
UPnP-compliant, and wish to take advantage of the UPnP features, you can enable the UPnP
feature. Select Enable in the UPnP Enabling section of the Utilities page, then click Apply
Changes to save the change.
Enabling/Disabling Auto Firmware Update
This innovation provides the router with the built-in capability to automatically check for a
new version of firmware and alert you that the new firmware is available. When you log into
the router's Web-Based Advanced User Interface, the router will perform a check to see if
new firmware is available. If so, you will be notified. You can choose to download the new
version or ignore it. The router ships with this feature enabled. If you want to disable it, select
Disable, then click Apply Changes.
Manually configuring network settings
In order for your computer to properly communicate with your router, you will need to
change your PC's TCP/IP settings to DHCP.

Troubleshooting
Placement of your router for optimal performance
Your wireless connection will be stronger the closer your computer is to your wireless router.
Typical indoor operating range for your wireless devices is between 100 and 200 feet. In the
same way, your wireless connection and performance will degrade somewhat as the
distance between your wireless router and connected devices increases. This may or may not
be noticeable to you. As you move farther from your wireless router, connection speed may
decrease.
48
Troubleshooting
Factors that can weaken signals simply by getting in the way of your network’s radio waves
are metal appliances or obstructions, and walls.
If you have concerns about your network’s performance that might be related to range or
obstruction factors, try moving the computer to a position between 5 and 10 feet from the
wireless router in order to see if distance is the problem.
Note: While some of the items listed below can affect network performance, they will not
prohibit your wireless network from functioning. If you are concerned that your network
is not operating at its maximum effectiveness, this checklist may help.
1. Placement of your wireless router
Place your wireless router, the central connection point of your network, as close as possible
to the center of your wireless network devices.
To achieve the best wireless network coverage for your “wireless clients,” (for example,
computers enabled by Wireless Notebook Cards, Wireless Desktop Cards, and Wireless USB
Adapters):
• Make sure that your wireless router’s antennas are parallel to each other, and are
positioned vertically (toward the ceiling). If your wireless router itself is positioned
vertically, point the antennas as much as possible in an upward direction.
• In multistory homes, place the wireless router on a floor that is as close to the center of
the home as possible. This may mean placing the wireless router on an upper floor.
• Try not to place the wireless router near a cordless 2.4 GHz phone.
2. Avoid obstacles and interference
Avoid placing your wireless router near devices that may emit radio “noise”, such as
microwave ovens. Other objects that can inhibit wireless communication can include:
• Refrigerators
• Washers or dryers
• Metal cabinets
• Large aquariums
• Metallic-based, UV-tinted windows
If your wireless signal seems weak in some spots, make sure that objects such as these are
not blocking the signal’s path between your computers and wireless router.
3. Cordless phone placement
If the performance of your wireless network is impaired after attending to the above issues,
and you have a cordless phone:
• Try moving cordless phones away from the wireless router and your wireless-enabled
computers.
• Unplug and remove the battery from any cordless phone that operates on the 2.4 GHz
band (check manufacturer’s information). If this fixes the problem, your phone may be
interfering.
Troubleshooting
49
• If your phone supports channel selection, change the channel on the phone to the
farthest channel from your wireless network as possible. For example, change the
phone to channel 1 and move your wireless router to channel 11. (Your channel
selection will vary depending on your region.) See your phone’s user guide for detailed
instructions.
• If necessary, consider switching to a 900 MHz or 5 GHz cordless phone.
4. Choose the “quietest” channel for your wireless network
In locations where homes or offices are close together, such as apartment buildings or office
complexes, there may be wireless networks nearby that can conflict with yours. Use the Site
Survey capabilities of your Wireless Networking Utility to locate any other wireless networks,
and move your wireless router and computers to a channel as far away from other networks
as possible.
Experiment with more than one of the available channels, in order to find the clearest
connection and avoid interference from neighboring cordless phones or other wireless
devices.
These guidelines should let you cover the maximum possible area with your router. If you
need to cover an even wider area, we suggest the Dynex Wireless Enhanced G Range
Extender/Access Point.
5. Secure connections, VPNs, and AOL
Secure connections typically require a user name and password, and are used where security
is important. Secure connections include:
• Virtual Private Network (VPN) connections, often used to connect remotely to an office
network
• The “Bring Your Own Access” program from America Online (AOL), which lets you use
AOL through broadband provided by another DSL or cable service
• Most online banking Websites
• Many commercial Websites that require a user name and password to access your
account Secure connections can be interrupted by a computer’s power management
setting, which causes it to “go to sleep.” The simplest solution to avoid this is to simply
reconnect by re-running the VPN or AOL software, or by re-logging into the secure
Web site.
A second alternative is to change your computer’s power management settings so it does not
go to sleep; however, this may not be appropriate for portable computers. To change your
power management setting in Windows, see the Power Options item in the Control
Panel.
If you continue to have difficulty with Secure Connections, VPNs, and AOL, review the items
above to be sure you have addressed these issues.
Problem: Installation CD does not automatically start.
Solution: If the CD does not start the Easy Install Wizard automatically, it could be that the

4. If the Easy Install Wizard still does not start, see “Manually configuring network settings”
on page 44 for an alternate setup method.
Problem: The Easy Install Wizard cannot find my router.
Solution: If the Easy Install Wizard is not able to find the router during the installation
process, please check the following items:
1. If the Easy Install Wizard is not able to find the router during the installation process, there
may be third-party firewall software installed on the computer attempting to access the
Internet. Examples of third-party firewall software are ZoneAlarm, BlackICE PC Protection,
McAfee Personal Firewall, and Norton Personal Firewall.
If you do have firewall software installed on your computer, please make sure that you
properly configure it. You can determine if the firewall software is preventing Internet access
by temporarily turning it off. If, while the firewall is disabled, Internet access works properly,
you will need to change the firewall settings to function properly when it is turned on.
Please refer to the instructions provided by the publisher of your firewall software for
instructions on configuring the firewall to allow Internet access.
2. Unplug the AC adapter r from the router for 10 seconds, and then plug the power back into
the router. Make sure that the router's power light is on and solid green. If not, make sure
that the AC adapter is correctly connected to the router and plugged into a wall outlet.
3. Make sure that you have a cable (use the cable included with the router) connected
between (1) the network (Ethernet) port on the back of the computer and (2) one of the LAN
ports, labeled “1” through “4”, on the back of the router.
Note: The computer should NOT be connected to the port labeled “Internet/WAN” on the back
of the router.
4. Try shutting down and restarting your computer, then rerunning the Easy Install Wizard.
If the Easy Install Wizard is still unable to find the router, see “Manually configuring network
settings” on page 44 for an alternate setup method.
Problem: The Easy Install Wizard cannot connect my router to the Internet.
Solution: If the Easy Install Wizard is not able to connect the router to the Internet, check
the following items:
1. Use the troubleshooting suggestions within the Easy Install Wizard. If the troubleshooting
screen does not open automatically, click the Troubleshoot button in the lower, right-hand
corner of the Easy Install Wizard window.
2. If your ISP requires a user name and password, make sure that you have typed in your user
name and password correctly. Some user names require that the ISP's domain be at the end
of the name. For example: myname@myisp.com. The @myisp.com part of the
user name may need to be typed as well as your user name.

Connected light is blinking.
Solution: If you cannot connect to the Internet, the WAN light is off, and the Connected light
is blinking, the problem may be that your modem and router are not connected properly.
1. Make sure the network cable between the modem and the router is connected. We
strongly recommend using the cable that was supplied with your cable or DSL modem for
this purpose. The cable should be connected at one end to the router's Internet/WAN port,
and at the other end to the network port on your modem.
2. Unplug the cable or DSL modem from its power source for three minutes. After three
minutes, plug the modem back into its power source. This may force the modem to properly
recognize the router.
3. Unplug the power to your router, wait 10 seconds, and then reconnect the power. This will
cause the router to reattempt communication with the modem.
4. Try shutting down and restarting your computer.

Problem: I can't connect to the Internet wirelessly.
Solution: If you are unable to connect to the Internet from a wireless computer, please do
the following:
1. Look at the lights on your router. They should be as follows:
• The Power light should be on.
• The Connected light should be on and not blinking.
• The WAN light should be either on or blinking.
2. Open your wireless utility software by clicking on the icon in the system tray at the bottom,
right-hand corner of the screen. If you are also using a Dynex wireless card or adapter with
this router, the tray icon should look like this
(the
icon may be red or green):
3. The exact window that opens will vary depending on the model of wireless card you have;
however, any of the utilities should have a list of Available Networks-those wireless
networks it can connect to.
Does the name of your wireless network appear in the results?
Yes, my network name is listed-go to the troubleshooting solution titled “I can't connect to
the Internet wirelessly, but my network name is listed”.
No, my network name is not listed-go to the troubleshooting solution titled “I can't connect
to the Internet wirelessly, and my network name is not listed”.
Problem: I can't connect to the Internet wirelessly, but my network name is listed.
Solution: If the name of your network is listed in the Available Networks list, please
follow the steps below to connect wirelessly:
1. Click on the correct network name in the Available Networks list.
2. If the network has security (encryption) enabled, you will need to enter the network key.
For more information regarding security, see “Securing your Wi-Fi® Network” on page 26.
3. Within a few seconds, the tray icon in the lower, left-hand corner of your screen should
turn green, indicating a successful connection to the network.
Troubleshooting
53
Problem: I can't connect to the Internet wirelessly, and my network name is not
listed.
Solution: If the correct network name is not listed under Available Networks in the
wireless configuration utility, please attempt the following troubleshooting steps:
1. Temporarily move your computer, if possible, 5 to 10 feet away from the router. Close the
wireless configuration utility, and reopen it. If the correct network name now appears under
Available Networks, you may have a range or interference problem. See the suggestions
discussed in “Placement of your router for optimal performance” on page 47.
2. Using a computer that is connected to the router through a network cable (as opposed to
wirelessly), make sure that Broadcast SSID is enabled. This setting is found on the router's
wireless Channel and SSID configuration page.
Problem: My wireless network performance is inconsistent.
Data transfer is sometimes slow.
Signal strength is poor.
I am having difficulty establishing and/or maintaining a Virtual Private Network
(VPN) connection.
Solution: Wireless technology is radio-based, which means connectivity and the
throughput performance between devices decreases when the distance between devices
increases. Other factors that will cause signal degradation (metal is generally the worst
culprit) are obstructions such as walls and metal appliances. As a result, the typical indoor
range of your wireless devices will be between 100 to 200 feet. Note also that connection
speed may decrease as you move farther away from the router or access point.
In order to determine if wireless issues are related to range, we suggest temporarily moving
the computer, if possible, five to 10 feet away from the router.
Changing the Wireless Channel
Depending on local wireless traffic and interference, switching the wireless channel of your
network can improve performance and reliability. The default channel the router is shipped
with is channel 11. You may choose from several other channels depending on your region
(see “Changing the Wireless Channel” on page 25 for instructions on how to choose other
channels).
Limiting the Wireless Transmit Rate
Limiting the wireless transmit rate can help improve the maximum wireless range, and
connection stability. Most wireless cards have the ability to limit the transmission rate. To
change this property, go to the Windows Control Panel, open Network Connections and
double-click on your wireless card's connection. In the Properties dialog box, select the
Configure button on the General tab (Windows 98 users will have to select the wireless
card in the list box and then click Properties), then choose the Advanced tab and select the
rate property. Wireless client cards are usually set to automatically adjust the wireless
transmit rate for you, but doing so can cause periodic disconnects when the wireless signal is
too weak; as a rule, slower transmission rates are more stable. Experiment with different
connection rates until you find the best one for your environment; note that all available
transmission rates should be acceptable for browsing the Internet. For more assistance, see
your wireless card's user manual.
54
Troubleshooting
Problem: How do I extend the range of my wireless network?
Solution: Dynex recommends using one of the following products to extend wireless
network coverage throughout large homes or offices:
• Wireless Access Point: A wireless access point can effectively double the coverage area
of your wireless network. An access point is typically placed in the area not currently
covered by your wireless enhanced G router, and is connected to the router using either
an Ethernet cable or through your home's power lines using two Powerline ethernet
adapters.
Problem: I am having difficulty setting up Wired Equivalent Privacy (WEP) security
on a Dynex wireless router or Dynex access point.
Solution:
1. Log into your wireless router or access point.
Open your web browser and type in the IP address of the wireless router or access point. (The
router's default is 192.168.2.1, the access point's default is 192.168.2.254.) Log into your
router by clicking on Login button in the top, right corner of the screen. You will be asked to
enter your password. If you never set a password, leave the password field blank, then click
Submit.
Click the Wireless tab on the left of your screen. Select the Encryption or Security tab to
get to the security settings page.
2. Select 128-bit WEP from the list.
3. After selecting your WEP encryption mode, you can type in your hex WEP key manually, or
you can type in a passphrase in the Passphrase field, then click Generate to create a WEP
key from the passphrase. Click Apply Changes to finish. You must now set all of your clients
to match these settings. A hex (hexadecimal) key is a combination of numbers and letters
from A-F and 0-9. For 128-bit WEP, you need to enter 26 hex characters.
For example: C3 03 0F AF 4B B2 C3 D4 4B C3 D4 E7 E4 = 128-bit key
4. Click Apply Changes to finish. Encryption in the wireless router is now set. Each of your
computers on your wireless network will now need to be configured with the same security
settings.
Caution: If you are configuring the wireless router or Access Point from a computer with a
wireless client, you will need to ensure that security is turned on for this wireless client. If
this is not done, you will lose your wireless connection.
Note to Mac users: Original Apple AirPort products support 64-bit encryption only. Apple
AirPort 2 products can support 64-bit or 128-bit encryption. Check your Apple AirPort
product to see which version you are using. If you cannot configure your network with
128-bit encryption, try 64-bit encryption.
Problem: I am having difficulty setting up Wired Equivalent Privacy (WEP) security
on a Dynex client card (wireless network card or adapter).
Solution: The client card must use the same key as the wireless enhanced G router or access
point. For instance, if your wireless router or access point uses the key
00112233445566778899AABBCC, then the client card must be set to the exact same key.
Troubleshooting

5. Type your WEP key in the Network key box.
Important: A WEP key is a combination of numbers and letters from A-F and 0-7. For
128-bit WEP, you need to enter 26 keys. This network key needs to match the key you
assign to your wireless enhanced G router or access point.
For example: C3030FAF4BB2C3D44BC3D4E7E4 = 128-bit key
6. Click OK, then click Apply to save the settings.
If you are NOT using a Dynex wireless client card, please consult the manufacturer's user
manual for that wireless client card.

routeur sans fil G amélioré de Dynex une solution idéale pour un réseau domestique ou un
réseau d’une petite entreprise.
Fonctionne avec ordinateurs PC et MacMD – Le routeur prend en charge divers
environnements de réseau, y compris Mac OSMD X, v10.x, LinuxMD, WindowsMD 2000, XP, VistaMC,
et autres. Tout ce qui est nécessaire est un navigateur Internet et une carte réseau compatible
avec TCP/IP (le langage standard d'Internet).
Témoins DEL sur le panneau avant – Les témoins DEL qui s'allument sur le devant du
routeur indiquent les fonctions actives. Il est possible de savoir d'un coup d'œil si le routeur
est connecté à Internet. Cette fonctionnalité élimine le besoin de logiciels avancés et de
procédures de contrôle d'état.
Interface utilisateur Web avancée – Les fonctions avancées du routeur peuvent être
facilement configurées par l'intermédiaire d'un navigateur Web, sans avoir à installer aucun
logiciel supplémentaire sur l'ordinateur. Aucun disque à installer ni à conserver et il est
possible d'apporter des modifications et d'exécuter des fonctions de configuration
rapidement et facilement à partir de n'importe quel ordinateur du réseau.
Partage d'adresse IP NAT – Le routeur utilise le protocole de traduction d'adresses réseau
(Network Address Translation, ou NAT) pour partager l'adresse IP unique assignée par le
fournisseur de service Internet, évitant ainsi le coût d'ajouter des adresses IP au compte
Internet.
Pare-feu SPI – Le routeur est équipé d'un pare-feu qui protégera le réseau contre un grand
nombre d’attaques habituelles de pirates, notamment l'usurpation d'adresse IP (IP
Spoofing), attaque Land, ping de la mort (Ping of Death, ou PoD), déni de service (Denial of
Service, ou DoS), IP de longueur nulle, attaque Smurf, TCP Null Scan, SYN flood, UDP
flooding, attaque Teardrop, défaut ICMP, défaut RIP et fragment flooding.
Commutateur 10/100 à 4 ports intégré – Le routeur dispose d’un commutateur réseau à
4 ports intégré afin que les ordinateurs câblés puissent partager imprimantes, données,
fichiers MP3, photos numériques et autres. Le commutateur dispose d’une fonction de
détection automatique de manière à s’ajuster à la vitesse des périphériques connectés. Il
transfère simultanément les données entre les ordinateurs et Internet sans interruption ni
consommation de ressources.
Compatibilité Universal Plug-and-Play (UPnP) – L’UPnP (Universal Plug-and-Play) est
une technologie qui offre un fonctionnement transparent de la messagerie vocale et vidéo,
des jeux et d’autres applications compatibles avec l’UPnP.
Caractéristiques du produit
65
Prise en charge de l'interconnexion de réseaux privés virtuels (VPN Pass-Through)
– En cas de connexion au réseau du bureau à partir de la maison, par l’intermédiaire d’une
connexion VPN, le routeur autorisera l’ordinateur équipé du système VPN à traverser le
routeur et à accéder au réseau du bureau.
DHCP (Dynamic Host Configuration Protocol) intégré – Le protocole DHCP (Dynamic
Host Configuration Protocol) intégré rend la connexion au réseau aussi simple que possible.
Le serveur DHCP attribue automatiquement des adresses IP à chaque ordinateur afin de
simplifier la configuration de la mise en réseau.
Assistant Installation facile – Grâce à l’Assistant Installation facile, la configuration du
routeur ne sera plus faite au hasard. Ce logiciel automatisé définit les paramètres du réseau
et configure le routeur de manière à se connecter au fournisseur d’accès Internet (FSI). En
quelques minutes, le routeur sans fil sera connecté à Internet.
Remarque : L'Assistant Installation facile est compatible avec Windows 2000, XP, Vista, ainsi
que Mac OS X 10.4.x. En cas d'utilisation d'un autre système d’exploitation, il est possible
de configurer le routeur sans fil à l’aide d’une autre méthode décrite dans ce Guide de
l'utilisateur (voir « Autre méthode de configuration » à la page 77).
Mode G amélioré* – Le mode G amélioré, une amélioration des performances de 54g,
fournit la connectivité sans fil la plus rapide pour des réseaux compatibles 802.11g dans les
environnements du monde réel. Il est conçu pour les réseaux à la maison qui nécessitent une
largeur de bande additionnelle pour des applications telles que le partage de photos
numériques. G amélioré rend les réseaux locaux sans fil (WLAN) 802.11g plus efficaces sans
pour cela interférer avec les performances des réseaux du voisinage; il est également
compatible aux produits à haut débit du marché.
* Lors d'un fonctionnement en G amélioré 125, ce dispositif Wi-Fi peut atteindre un débit réel
égal ou supérieur à 34,1 Mbps, ce qui est le débit équivalent d'un système suivant le
protocole 802.11g et fonctionnant à un débit de données de 125 Mbps. Le débit réel
variera en fonction de l'environnement, des conditions d'utilisation et d'autres facteurs.
Point d’accès sans fil 802.11g intégré – La nouvelle technologie sans fil 802.11g procure
une vitesse réseau près de cinq fois supérieure à la norme Wi-Fi actuelle (802.11b), soit
54 Mbps.
Filtrage d’adresses MAC – Pour une plus grande sécurité, il est possible de créer une liste
d’adresses MAC. Il s’agit des identificateurs uniques des clients qui sont autorisés à accéder au

Touche de
synchronisation de
sécurité
Appuyer sur cette touche pendant trois secondes, puis initier la procédure de
synchronisation de sécurité (WPS) sur le périphérique client dans les deux minutes
suivantes. Le client échangera automatiquement les informations de sécurité et sera
ajouté au réseau sans fil. Le fait d'appuyer sur la touche de synchronisation de
sécurité activera automatiquement WPS. Voir « Utilisation de la synchronisation de
sécurité (WPS) » à la page 90.
DEL de
synchronisation de
sécurité
S’allume pour indiquer que WPS a été activé.
Vert clignotant – Le routeur cherche un client WPS pour établir une connexion.
Vert continu – La connexion sécurisée a été établie avec le client.
DEL du réseau sans fil Éteint – Le réseau sans fil est éteint
Vert continu – Le réseau sans fil est prêt
Vert clignotant – Activité du réseau
DEL Internet
DEL d'état du modem Cette DEL s'allume en vert pour indiquer que le modem est correctement connecté
au routeur. Elle clignote rapidement lorsque des informations transitent par le port
entre le routeur et le modem.
Éteint – Aucune liaison WAN
Vert continu – Bonne liaison WAN
Vert clignotant – Activité WAN
DEL d'état des
ordinateurs câblés
Cette DEL unique indique lorsque le routeur est connecté à l’Internet. Lorsque le
témoin est éteint, le routeur n’est pas connecté à l’Internet. Lorsque le témoin
clignote, le routeur essaye de se connecter à l’Internet. Lorsque le témoin reste
allumé en vert, sans clignoter, le routeur est connecté à l’Internet. Lors de
l'utilisation de la fonction « Disconnect after x minutes » (Déconnecter après x
minutes), cette DEL devient très utile pour surveiller l'état de la connexion du
routeur.
Éteint – Le routeur n’est pas connecté à l’Internet
Vert clignotant – Le routeur essaye de se connecter à l’Internet
Vert continu – Le routeur est connecté à l’Internet
Ces DEL portent les numéros 1 à 4 et correspondent aux numéros des ports à l’arrière
du routeur. Lorsqu’un ordinateur est correctement connecté à l’un des ports pour
ordinateurs câblés à l’arrière du routeur, la DEL correspondante s'allume : vert
signifie qu’un périphérique 10Base-T est connecté, ORANGE signifie qu’un
périphérique 100Base-T est connecté. Lorsque des informations sont envoyées par le
port, la DEL clignote rapidement.
Éteint – Le réseau sans fil est éteint
Vert continu – Un périphérique 10base-T est connecté
Orange continu – Un périphérique 100base-T est connecté

Installation du routeur sans fil
Installation du routeur sans fil
Configuration requise pour le modem
Le modem câble ou DSL doit être équipé d’un port Ethernet RJ45. De nombreux modems
possèdent à la fois un port Ethernet RJ45 et une connexion USB. Si le modem en service est à
la fois Ethernet et USB, et que la connexion USB est celle qui est utilisée à ce moment-là, un
message demandera d’utiliser le port Ethernet RJ45 pendant la procédure d’installation. Si le
modem est équipé uniquement d’un port USB, il faudra demander un autre type de modem
au FSI ou, dans certains cas, acheter un modem équipé d’un port Ethernet RJ45.
Important : Toujours installer d’abord le routeur! En cas d’installation de plusieurs
dispositifs réseau pour la première fois, il est important que le routeur soit connecté et
fonctionne avant d'essayer d’installer d'autres composants réseau, tels que les cartes pour
ordinateurs portatifs ou pour ordinateurs de bureau.
Assistant Configuration
Dynex propose un Assistant Configuration pour rendre l’installation du routeur simple et
facile. Grâce à lui, le routeur peut être prêt à fonctionner en quelques minutes. L’Assistant
Configuration requiert que l’ordinateur sous Windows 2000 ou XP soit connecté directement
au modem câble ou DSL et que la connexion à l’Internet soit active et qu’elle fonctionne au
moment de l’installation. Si ce n'est pas le cas, il faudra utiliser la section « Autre méthode de
configuration » de ce Guide de l'utilisateur pour configurer le routeur. En outre, si le système
d’exploitation utilisé n'est pas Windows 2000 ou XP, il faudra configurer le routeur en
utilisant également la section « Autre méthode de configuration » de ce Guide de
l'utilisateur.
Connexion du matériel
Pour connecter le matériel :
1 Débrancher le cordon d'alimentation du modem. Placer le routeur à côté du modem et
relever les antennes du routeur.
2 Repérer le câble réseau qui permet de connecter le modem et l'ordinateur. Débrancher
ce câble du modem et le connecter à l'un des ports de couleur bleue à l'arrière du
routeur.
3 Prendre le nouveau câble réseau (inclus dans la boîte avec le routeur) et le connecter
au port de couleur verte à l'arrière du routeur. Connecter l'autre extrémité au modem,
dans le port qui est maintenant libre.
4 Brancher le cordon d'alimentation du modem. Attendre 60 secondes pour permettre
au modem de s'initialiser. Brancher l'alimentation du routeur sur le port de couleur
noire situé à l'arrière du routeur. Brancher l’autre extrémité sur une prise secteur.
5 Attendre 20 secondes pour permettre au routeur de s'initialiser. Vérifier que le témoin
Modem et l'un des témoins Wired Computers (Ordinateurs connectés) sont allumés
en vert sur la face avant du routeur. Si ce n'est pas le cas, vérifier de nouveau les
connexions.
