Congratulations! 

Thank you for choosing the Linksys EtherFast

®

Cable/DSL Firew

all

Router . The Router allo

ws you to set up a home or small business 

network

to share

your high-speed Internet connection.

Why do I need a network?

Networks ar

e useful for sharing computer resour

ces

such as printers,

files,and CD-ROM

drives. Networks ar

e even used for playing mul-

tiplayer video games. So

,not only ar

e networks useful in homes and businesses,

but

they can also be used for fun.

The most remarkable thing the Router does is to let you shar

e your high-speed cable

or DSL connection to the Internet. 

The Router connects your LAN (Local Ar

ea

Network) to a 

WAN (Wide 

Area Netw

ork). The Inter

net is a network that,

being glob-

al,co

vers the widest area of all! 

All PCs connected to the Router can share this con-

nection.

How is this accomplished?

You will be setting up a simple LAN

. Your PCs ar

e con-

nected via Ethernet cable from an Ether

net adapter (in or attached to your PC) to one

of the Router’s

 LAN ports. The ter

m “Ether

net”is used to r

efer to your network

accessories,suc

h as cables and adapters,because Ether

net refers to the type of

network you ar

e setting up. 

Then the Router is connected to your cable or DSL modem. The Router mak

es it

seem as if each PC is connected dir

ectly to the Internet. Sever

al PCs can then use

one Internet connection simultaneously

.

Use the 

Linksys Router Setup Wizard CD-ROM

or the instructions in this 

Fast

Start

to help you connect the Router ,configur

e your PCs,and configur

e the Router . 

These instructions will get you up and running quickly using the most basic settings.

Once you have access to the Inter

net,you can get adv

anced configuration infor

ma-

tion (for gaming,

VPNs,

web hosting,

etc.) b

y visiting our website at

support.linksys.comor b

y r

eading the User Guide on the Setup Wizar

d CD-ROM.

B.

Using the Ethernet cable that came with your cable

or DSL modem,connect the LAN or Ether

net port of

the cable or DSL modem to the W

AN port of the

Router .

C.

Connect an Ethernet cable to your PC’

s Ethernet adapter

. Connect the other end of

the cable to one of the LAN ports on the back of the Router

. Repeat this process for

every PC you wish to connect to the Router

.

Note:If your PC’

s Ethernet adapter is not set up

,please refer to the Ether

net

adapter’s

 user guide for more infor

mation.

Note:For ease of installation,

start with LAN Port 4/DMZ,then Port 3,

then Port 2,

and finally Port 1.

If you are connecting mor

e than four PCs to the Router ,you will need to connect

a hub or switch to Port 1,

2,3,

or 4/DMZ of the Router . Please r

efer to the User

Guide located on the Setup Wizar

d CD-ROM.

D.

Connect the power adapter to the Router

. Connect

the power adapter to the electrical outlet. 

Tur

n on

the cable or DSL modem. Then tur

n on the first PC

you wish to use to configure the Router

.

Proceed to Step 2: Configur

e the PCs on the next page.

In Step 1,you will connect the Router to your cable or DSL modem and to the com-

puters in your home or business.

First,mak

e sure that all devices you’ll be w

orking with are po

wered do

wn,includ-

ing your PCs,modem,

and the Router .

A.

If you haven’t alr

eady done so

,connect your cable or DSL modem to its proper

connection—the coaxial jack for cable (Figur

e A

1

),or the phone jac

k for DSL

(Figure A

2

). (Follow the instructions from your cable or DSL modem’

s installation

guide.)

In Step 2, you will configure each of your computers to be able to communicate with
the Router.

To do this, you need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically (called DHCP). Computers use IP addresses to com-
municate with each other across a network or the Internet.

Find out which operating system your computer is running, such as Windows 95, 98,
Millennium, NT 4.0, 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 going to the 

Settings

option. Then

click 

Control Panel

, and then double-click the 

System

icon. If your Start menu

doesn’t have a Settings option, you’re running Windows XP. Click the 

Cancel 

button

when done.

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 network settings
based on the type of Windows operating system you are using. Once you've config-
ured your computers, continue to Step 3: Configure the Router.

for the applicable Ethernet adapter*. If

the word 

TCP/IP

“D” is the letter of your CD-ROM drive).

F.

Windows may ask 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 user guide to install TCP/IP now.
