Uplink The Uplink Port is where you can expand your net-

work by connecting to another switch or hub. The

Uplink Port is shared with Port 4. Uplinking to

another switch or a hub is done by simply running

a cable from the Uplink Port to the other device. If

the Uplink port is being used, Port 4 will not work.

Power The Power Port is where you will connect the

included AC Power adapter.

Antenna Jacks The Antenna Jacks are where you will connect the

included antennas.

The Reset Button*

Briefly pressing the Reset Button will refresh the Router’s connec-

tions, potentially clearing any jammed links.

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 the entire system(s).

If your router locks up, simply power it down for 3 to 5 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.

ing or receiving data over that port.

Full/Col Green. The Full/Col LED also serves two purposes. If this

LED is continuously illuminated, the connection made

through the corresponding port is successfully running in

Full Duplex mode. If the LED is flickering, the connection

is experiencing collisions. Infrequent collisions are normal.

If this LED is flickering too often, there may be a problem

with your connection. Check the Troubleshooting section if

you think there is a problem.

A dynamic IP address may change every time your computer connects to the

network.

DHCP (Dynamic Host Configuration Protocol) DHCP is software that automati-

cally assigns IP addresses to client stations logging onto a TCP/IP network.

DHCP eliminates having to manually assign permanent IP addresses to every

device on your network. DHCP software typically runs in servers and is also

found in network devices such as Routers.

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 your Wireless Access Point + Cable/DSL Router.

1. Power everything down, including your PCs, your Cable or DSL modem

and the Router.

2. Connect a Network cable from one of your PCs’ Ethernet ports to one of

the LAN Ports on the back of the Router. 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.)

3. Connect the network cable from your Cable or DSL modem to the WAN

port on the rear of the Router.

4. Connect the power-supply cable to the Power port on the rear of the

Router, then plug the supplied AC power cable into a power outlet.

• The Power LED will illuminate green as soon as the power adapter is

connected.

• The Diag LED will illuminate red for a few seconds while the Router

goes through its internal diagnostic test. The LED will turn off when the

self-test is complete.

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.

Connecting the Wireless

Access Point + Cable/DSL

Router to Your Network

Overview

Unlike a simple hub or switch, the setup of the Wireless Access Point +

Cable/DSL Router consists of more than simply plugging everything together.

Because the Router acts as a DHCP server, you will have to set some values

within the Router, and also configure your networked PCs to accept the IP

Addresses the Router chooses to assign them.

You will need the following values from your ISP in order to install the

Wireless Access Point + Cable/DSL Router:

• Your broadband-configured PC’s fixed Internet IP Address (if applicable)

• Your broadband-configured PC’s Computer Name and Workgroup Name

• Your Subnet Mask

• Your Default Gateway

• Your Primary DNS IP address

Whoever installed your broadband access should have left this information

with you. If not, call your ISP and they will be able to supply you with it.

About Static & Dynamic IP Addresses

Static IP Addresses A static IP address is an IP address permanently assigned

to computer in a TCP/IP network. Static IP addresses are usually assigned to

networked devices, which are consistently accessed by multiple users, such as

Server PCs, or print server. If you are using your Router to share your cable

or DSL Internet connection, contact your ISP to see if they have assigned

your home a static IP address. You will need that address during your Router’s

configuration.

Dynamic IP Addresses A dynamic IP address is an IP address that is automati-

cally assigned to a client station (computer, printer, etc.) in a TCP/IP network.

Dynamic IP addresses are typically assigned by a DHCP server, which can be

a computer on the network or another piece of hardware, such as the Router.

}Only if applicable

Instant BroadbandTM Series

Now that your Router is physically installed, you will have to configure your

PCs to accept the IP addresses that your Router will provide.

1. Click the Start button, select Settings, then Control Panel.

2. Double-click the Network icon.

3. In the Configuration window, select the TCP/IP protocol line that has

been associated with your network card/adapter.

These instructions apply only to Windows 95, 98 and

Millennium machines. For TCP/IP setup under Windows NT or

Windows 2000, please refer to your Microsoft Windows NT or

Windows 2000 manual.

WEP (Wired Equivalent Privacy) Encryption is a method of encrypting data

that is transmitted over your wireless network to insure data security. In a

wired network, data security is maintained through the physical wire. WEP

Encryption provides the same level of security for your wireless data as if it

were being transmitted over standard network cabling (which is how the name

is derived). In order to duplicate wired network security levels, wireless data

is encrypted at its point of transmission. It is decoded by the receiving

device. This allows users to have the same amount of security over their

wireless network as they would over a wired network. This level of security

is above that already provided by the use of password protection by your net-

work operating system.

The present standard for this encryption, set by the IEEE (the Institute of

Electrical and Electronics Engineers), is defined as 40-bit (sometimes also

called 64-bit) encryption. Like many manufacturers, Linksys also includes a

higher level of encryption, identified as 128-bit. These numbers refer to the

complexity of the algorithms generated in order to code and decode the data

transmitted. The higher the bit number, the greater the complexity of the

algorithm, which is designed to provide a more secure the encryption. Be

aware, however, that higher levels of encryption often negatively affect net-

work data transmission rates. This encryption is not necessary for the

operation of your wireless network device. Your need for security can only

be determined by you. If your security needs are such that ordinary password

protection is sufficient, you may decide not to use the additional WEP

Encryption. However, should your security needs dictate it, the Wireless

Access Point + Cable/DSL Router can provide as secure a connection as is

available in wireless networking.

1. At the Setup Screen, if you choose to enable

WEP Encryption, select Mandatory under the

WEP section.

2. Press the WEP Key Setting button to set the

WEP Encryption type and level.

It is strongly recommended that you set a password for the router. When you

first power up the router, you will notice that the Password setting default is

“admin”. For security, we recommend that you change your password often.

To change your password, enter your new password in the Router Password

box. Enter it again in the box just below the Router Password box, exactly as

you typed it in the first box. When you are sure you have entered the pass-

word as you want it, press the Apply button.

If you set the Restore Factory Default option and click Apply,

you will clear all of the router’s settings. Do not restore to the

factory defaults unless you want to completely set up the

Router again. Once the Router is reset, you will have to re-

enter your configuration.

2. You may enter the encryption key manually.

(The Passphrase method is recommended; however, you may need to enter

a manual key in order to meet the requirements of existing wireless equip-

ment on your network. If you are unsure, check with your System

Administrator.)

In either case, you should commit this Passphrase or Manual Key to memory.

You will probably need it for other 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.

Dynamic Routing

With Dynamic Routing you can automatically adjust to physical changes in

the network's layout. The router, using the RIP protocol, determines the net-

work packets’ route based on the fewest number of hops between the source

and the destination. The RIP protocol regularly broadcasts routing informa-

tion to other routers on the network. To set up Dynamic Routing:

1. Choose the correct working mode. Gateway Mode should be used if your

Linksys 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.

2. In the TX field, choose the protocol by which you transmit data on the

network.

3. In the RX field, choose the protocol by which the Router receives net-

work data.

4. Click the Apply button to save your changes.

Dynamic Routing

For

Port forwarding sets up public services on your network. When users from the

Internet make certain requests of your network, the router will forward those

requests to the appropriate computer. The router's DHCP function must be

disabled to use Forwarding.

Forwarding is generally used to set up a web server, ftp server, or e-mail serv-

er on your network. To add a server using Forwarding:

1. Enter the port number or range used by the server. On the same line,

select TCP, UDP or Both. Enter the IP Address of the server that you

want the Internet users to be able to access. Refer to your software docu-

mentation for more information concerning which service port settings

may need to be changed, if any.

2. Configure as many entries as you would like until all of the link entries

are filled.

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 network portion

of the IP address is set to zero (0). 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, with the last digit (1, in

this case) determining the Router’s place on the network. Therefore you

would enter the IP address 192.168.1.0 if you wanted to route to the

Router’s entire network, rather than just to the Router.

Network Mask The Network Mask (also known as the Subnet Mask)

determines which portion of an IP address is the network portion, and

which portion is the host portion. In the example above the Network

Mask is 255.255.255.0. This determines (by using the values 255) that the

first three numbers of an network IP address identify this particular net-

work, while the last digit (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.

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 sub-

network, select LAN. If you’re connecting to another network through

the Internet, select WAN.

3. Click the Apply button to save your changes.

Static Routing

If your Router is connected to more than one network, it may be necessary to

set up a static route between them. 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 con-

figuration.

To create a static route entry:

1. Select Static Route Entry from the drop down list. The Cable/DSL

Router supports up to 20 static route entries.

MAC Address Cloning allows you to assign the Router a MAC address,

which is a 12-digit code assigned to a unique piece of hardware for identifi-

cation, like a social security number. Some ISPs require that you register the

MAC address of your network card/adapter, which was connected to your

cable or DSL modem during installation. You can find your adapter's MAC

address by doing the following:

• If you are running Windows 95, 98 or Millennium:

Go to Start, Run, type in command, and press Enter. At the DOS

prompt, type winipcfg.

• If you are running Windows NT 4.0 or 2000:

Go to Start, Run, type in command, and press Enter. At the DOS

prompt, type ipconfig /all. The Physical Address with 12 digits is your

adapter’s MAC address.

Enter those 12 digits into the fields on this screen, and click Apply. This

“clones” your network adapter’s MAC address onto your Router, and prevents

you from having to call your ISP to change the registered MAC address to the

adapter’s MAC address. Z Host

ing Run, and typing winipcfg in the Run box and press Enter. The

PC should have an IP address of 192.168.1.xxx ("xxx" is from 2 to

254.) Subnet Mask is 255.255.255.0, the default gateway IP should be

the Router’s IP Address, and DNS (in "More".)

• Same as above, check the same setup values in the Status Monitor page

of the Wireless AP + Cable/DSL Router.

4. When I enter a URL or IP address, I get a time out error.

• Check if other PCs work. If they do, ensure that your workstations IP

settings are correct (IP address, Subnet Mask, Default gateway and

DNS)

• If the PCs are configured correctly, but still not working, check the

Wireless Access Point + Cable/DSL Router. Ensure that it is connected

and ON. Connect to it and check its settings. (If you cannot connect to

it, check the LAN and power connections.)

• If the Cable/DSL Router is configured correctly, check your Internet

connection. (DSL/Cable modem etc.) to see that it is working correctly.

• Manually configure the TCP/IP with a DNS address provided by your

ISP.

5. I can’t obtain an IP address from my cable or DSL modem.

• Ensure that all of your cabling is properly connected and that all of the

router’s WAN and LAN LEDs are correctly illuminated.

• Power down your cable or DSL modem for a few seconds. Turn it back

on. After the modem goes through its self-test, check to see if you now

have an IP address.

• Ensure that your cable or DSL modem is DHCP-capable.

• You may have to enter the router or host name in the Setup page of the

Router’s web-based utility. Go to the Setup section of the Web-based

Utility for more information.

• Your ISP may require Mac Addresses. Check with your ISP. This

address can be obtained in the Status screen of the Router’s Web-based

Utility.

Frequently Asked Questions

Troubleshooting

Common Problems and Solutions

This section provides possible solutions to problems regarding the installation

and operation of the Wireless Access Point + Cable/DSL Router. If your situ-

ation is described here, the problem should be solved by applying the corre-

sponding solution. If you can’t find an answer here, check the Linksys web-

site at www.linksys.com.

1. I Can’t connect to the Wireless Access Point + Cable/DSL Router.

• The Wireless AP + Cable/DSL Router is properly installed, LAN con-

nections are OK, and it is powered ON.

• Ensure that your PC and the Wireless AP + Cable/DSL Voice Router

are on the same network segment. If you are not sure, initiate the

DHCP function, let the PC get the IP address automatically.

• Ensure that your PC is using an IP Address within the default range of

192.168.1.2 to 192.168.1.254 and thus compatible with the Wireless AP

+ Cable/DSL Router default IP Address of 192.168.1.1

• Also, the Subnet Mask should be set to 255.255.255.0 to match the

Wireless AP + Cable/DSL Router. In the Wireless AP + Cable/DSL

Router, you can check these settings by using Control Panel-Network to

check the Properties for the TCP/IP protocol.

2. The Diag LED stays lit when it shouldn’t.

• The Diag LED lights up when the device is first powered up.

Meantime, the system will boot up itself and check for proper opera-

tion. After finishing the checking procedure, the LED turns off to show

the system is working fine. If the LED remains lit after this time, the

device is not working properly. Try to re-flash the firmware by assign-

ing a static IP address to the computer, then upgrade the firmware

again. If that doesn’t help, contact your dealer for further inspection.

Does the Wireless Access Point + Cable/DSL Router support any operating sys-

tem other than Windows 95,Windows 98,Windows 2000, or Windows NT? Yes,

but Linksys does not, at this time, provide technical support for setup, con-

figuration or troubleshooting of any non-Windows operating systems.

Does the Cable/DSL router support ICQ send file? Yes, with the following fix:

ICQ menu-> preference -> connections tab-> check "I am behind a firewall

or proxy", and set the firewall time-out to 80 seconds in firewall setting.

The Internet user can then send a file to a user behind the router.

How do I get Napster to work with the Router? Napster is fully compatible

with the Router, but you must make sure that, during installation, you select

“no idea” when asked about your firewall selection. Set your proxy settings

to “No Proxy Server” in your File>Preferences.

I setup 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. If you want to use the UT Server Admin, forward another port (8080

usually works well), 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 simultaneous-

ly with just one public IP address? It depends on the 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" 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 of the server computer.

There remains, however, a problem with people being booted after a few

minutes with an "illegible server message."

What is the maximum number of IP addresses that the Wireless Access Point +

Cable/DSL Router will support? The Router will support up to 253 IP address-

es.

Is IPSec Pass-Thru supported by the Router?Yes, it is a built-in feature that the

router automatically enables.

Where is the Wireless Access Point +Cable/DSL Router installed on the network?

In a typical environment, the Router is installed between the Cable/DSL

Modem and the LAN. Plug the Wireless AP +Cable/DSL Router into the

Cable/DSL Modem's Ethernet port.

Does the Wireless Access Point + Cable/DSL 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 net-

works, can be used from LAN to LAN connections, but those protocols can-

not connect from WAN to LAN.

Does the WAN connection of the Wireless Access Point + Cable/DSL Router sup-

port 100Mb Ethernet? Because of the speed limitations of broadband Internet

connections, the Cable/DSL Router’s current hardware design supports

10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over

in 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 Cable/DSL Router

to be used with low cost Internet accounts, such as DSL or cable modems,

where 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.

upgrades are posted on the Linksys website at www.linksys.com, where

they can downloaded for free. The router's firmware can be upgraded with

TFTP programs.

Does the Wireless Access Point + Cable/DSL Router support IPSec? Yes, but

only pass through IPSec is supported.

Will the router function in a Macintosh environment? Yes, but the router's setup

pages are accessible only through Internet Explorer v4.0 or Netscape

Navigator v4.0 or higher for Macintosh.

With which type of firewall is the router equipped? The Wireless AP +

Cable/DSL router uses NAT and TCP/IP port inspections.

Does the Router do Stateful packet inspection? No

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.

What is DMZ? 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 stat-

ic IP if you want to use DMZ.

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.

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 less

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

Appendix

How to Ping Your ISP’s E-mail & 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. Type it

into your web browser and you will wind up at the Linksys home page every

time.

IP and web addresses, however, can sometimes be long and hard to remem-

ber. 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 E-mail and Web server addresses are configured with single words

(“www”, “e-mail”, “home”, “pop3”, etc.) rather than whole Internet

Addresses or IP Addresses, your Router may have problems sending or

receiving mail and accessing the Internet. This happens because your 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 ISPs code

words. You can determine the IP and web addresses of your ISP’s servers by

“pinging” them.

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 your Cable/DSL 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.

2. Click Start, then Run, and type "command". This will bring up the DOS

Window.

Follow these instructions to install the TCP/IP Protocol on one of your PCs

only after a network card has been successfully installed inside the PC. These

instructions are for Windows 95, 98 or Milliennium. For TCP/IP setup under

Microsoft Windows NT or 2000, please refer to your Microsoft Windows NT

or 2000 manual.

1. Click the Start button. Choose Settings, then Control Panel.

2. Double-click the Network icon. Your Network window should pop up.

Select the Configuration tab.

3. Click the Add button.

4. Double-click Protocol.

5. Highlight Microsoft under the list of manufactures.

Installing the TCP/IP Protocol

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,

your Router should have no problem accessing the Internet through that

Internet application.

There are different grades, or categories, of twisted-pair cabling. Category 5

is the most reliable and is highly recommended. Category 3 is a good second

choice. Straight-through cables are used for connecting computers to a hub.

Crossover cables are used for connecting a hub to another hub (there is an

exception: some hubs have a built-in uplink port that is crossed internally,

which allows you to link or connect hubs together with a straight-through

cable instead).

You can buy pre-made Category 5

cabling, or cut and crimp your own.

Category 5 cables can be purchased

or crimped as either straight-through

or crossover. Inside a Category 5

cable are 8 thin, color-coded wires

inside that run from one end of the

cable to the other. All 8 wires are

used. In a straight-through cable,

wires 1, 2, 3, and 6 at one end of the

cable are also wires 1, 2, 3, and 6 at

the other end. In a crossover cable,

the order of the wires change from

one end to the other: wire 1 becomes

3, and 2 becomes 6.

See the diagrams on the

next page for more

detailed information on

straight-through and

crossover cabling.

To determine which wire is wire number 1, hold the cable

so that the end of the plastic RJ-45 tip (the part that goes

into a wall jack first) is facing away from you. Face the clip

down so that the copper side faces up (the springy clip will

now be parallel to the floor).When looking down on the

copper side, wire 1 will be on the far left.

Twisted-Pair Cabling

6. Find and double-click TCP/IP in the list to the right (below).

7. After a few seconds you will be brought back to the main Network win-

dow. The TCP/IP Protocol should now be listed.

8. Click OK. Windows may ask for original Windows installation files.

Supply them as needed (i.e.: D:\win98, D:\win95,

c:\windows\options\cabs.)

9. Windows will ask you to restart the PC. Click Yes.

The TCP/IP Installation is complete.

Glossary

Ad-hoc Network - An ad-hoc network is a wireless network or other small net-

work in which some of the network devices are part of the network only for the

duration of a communications session while in some close proximity to the rest

of the network.

BSS (Basic Service Set) - A group of Instant WirelessTM Network PC Card

users and a Wireless AP + Cable/DSL Router.

Default Gateway - The router used to forward all traffic that is not addressed

to a station within the local subnet.

DHCP (Dynamic Host Configuration Protocol) - Aprotocol 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 con-

nection 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.

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 espe-

cially useful in education and other environments where users change fre-

quently. Using very short leases, DHCP can dynamically reconfigure networks

in which there are more computers than there are available IP addresses.

DHCP supports static addresses for computers containing Web servers that

need a permanent IP address.

DMZ - A DMZ (demilitarized zone) is a computer host or small network

inserted as a "neutral zone" between a company's private network and the out-

side public network. It prevents outside users from getting direct access to a

server that has company data.

EtherFast® Wireless Access Point + Cable/DSL Router with 4-Port Switch

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.

DSSS - Also known as “Direct Sequence Spred Spectrum”, this is a variety of

radio transmission methods that continuously change frequencies or signal pat-

terns. Direct sequence spread spectrum (DSSS), which is used in CDMA, mul-

tiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that

"spreads" the data into a large coded stream that takes the full bandwidth of the

channel

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.

ESS - More than one BSS in a network.

FHSS - Also known as “Frequency Hopping Spread Spectrum”. Frequency

hopping spread spectrum (FHSS) continuously changes the center frequency of

a conventional carrier several times per second according to a pseudo-random

set of channels, while chirp spread spectrum changes the carrier frequency.

Because a fixed frequency is not used, illegal monitoring of spread spectrum

signals is extremely difficult, if not downright impossible depending on the

particular method.

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 program, examines each

network packet to determine whether to forward it toward its destination.

Firmware - Programming that is inserted into programmable read-only mem-

ory (programmable read-only memory), thus becoming a permanent part of a

computing device.

IEEE - The Institute of Electrical and Electronics Engineers. The IEEE

describes itself as "the world's largest technical professional society -- promot-

ing 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 - An infrastructure network is a wireless network or other small

network in which the wireless network devices are made a part of the network

through the Access Point which connects them to the rest of the network.

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 identi-

fies 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.

IPCONIFG - A utility that provides for querying, defining and managing IP

addresses within a network. A commonly used utility, under Windows NT and

2000, for configuring networks with static IP addresses.

IPSec - IPSec (Internet Protocol Security) is a developing standard for securi-

ty at the network or packet processing layer of network communication. A big

advantage of IPSec is that security arrangements can be handled without

requiring changes to individual user computers.

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).

MAC Address - The MAC (Media Access Control) address is your computer's

unique hardware number.

mIRC - mIRC runs under Windows and provides a graphical interface for log-

ging onto IRC servers and listing, joining and leaving channels.

NAT - NAT (Network Address Translation) is 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 Mask - also known as the “Subnet Mask”.

Packet Filtering - Discarding unwanted network traffic based on its originat-

ing address or range of addresses or its type (e-mail, file transfer, etc.).

PCMCIA - The PCMCIA (Personal Computer Memory Card International

Association) is an industry group organized in 1989 to promote standards for a

credit card-size memory or I/O device that would fit into a personal computer,

usually a notebook or laptop computer.

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 send-

ing out a packet and waiting for a response.

PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL

providers for connecting personal computers to a broadband modem for

Internet access. It is similar to how a dial-up connection works but at higher

speeds and quicker access.

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.

PrintServer - A hardware device that enables a printer to be located anywhere

in the network.

RJ-45 - A connector similar to a telephone connector that holds up to eight

wires, used for connecting Ethernet devices.

Roaming - The ability to use a wireless device and be able to move from one

access point’s range to another without losing the connection.

Static IP Address - A permanent IP address that is assigned to a node in a

TCP/IP network.

Subnet Mask - The method used for splitting IP networks into a series of sub-

groups, 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.

TCP (Transmission Control Protocol) - A method (protocol) used along with

the Internet Protocol (Internet Protocol) to send data in the form of message

units between computers over the Internet. While IP takes care of handling the

actual delivery of the data, TCP takes care of keeping track of the individual

units of data (called packet) that a message is divided into for efficient routing

through the Internet.

TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the

basic communication language or protocol of the Internet. It can also be used

as a communications protocol in a private network (either an intranet or an

extranet). When you are set up with direct access to the Internet, your comput-

er is provided with a copy of the TCP/IP program just as every other computer

that you may send messages to or get information from also has a copy of

TCP/IP.

UDP (User Datagram Protocol) - A communications method (protocol) that

offers a limited amount of service when messages are exchanged between com-

puters in a network that uses the Internet Protocol (IP). UDP is an alternative

to the Transmission Control Protocol (TCP) and, together with IP, is sometimes

referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the

Internet Protocol to actually get a data unit (called a datagram) from one com-

puter to another. Unlike TCP, however, UDP does not provide the service of

dividing a message into packets (datagrams) and reassembling it at the other

end. Specifically, UDP doesn't provide sequencing of the packets that the data

arrives in. This means that the application program that uses UDP must be able

to make sure that the entire message has arrived and is in the right order.

Network applications that want to save processing time because they have very

small data units to exchange (and therefore very little message reassembling to

do) may prefer UDP to TCP.

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 electro-

magnetic 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.

defining and managing IP addresses within a network. A commonly used util-

ity, under Windows 95, 98, and Millennium, for configuring networks with

static IP addresses.
