You may have different computers than what are pictured here, but the setup is
similar. The Router lets you share your fast cable or DSL connection among
several computers in your home or business. This is called a Local Area
Network or LAN.
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
Connect the Router to your cable or DSL modem and to your notebook or desk-
top PCs.
Step 2: Configure the PCs
Configure your notebook or desktop PCs to be able to communicate with the
Router.
Step 3: Configure the Router
Do the basics to get the Router to work with your cable or DSL modem and
your ISP’s settings.

Introduction
Congratulations! Thank you for choosing the Linksys EtherFast®Cable/DSL
Router. The Router allows you to set up a home or small business network to
share your high-speed Internet connection.
Why do I need a network? Networks are useful for sharing computer
resources such as printers, files, and CD-ROM drives. Networks are even used
for playing multiplayer video games. So, not only are 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 share your high-speed
cable or DSL connection to the Internet.The Router connects your LAN (Local
Area Network) to a WAN (Wide Area Network). The Internet is a network that,
being global, covers the widest area of all. All PCs connected to the Router can
share this connection.
How is this accomplished?You will be setting up a simple LAN.Your PCs are
connected via Ethernet cable from an Ethernet adapter (in or attached to your
PC) to one of the Router’s LAN ports. 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.
The Router is then connected to your cable or DSL modem. The Router makes
it seem as if each PC is connected directly to the Internet. Several PCs can then
use one Internet connection simultaneously.
Use the Linksys Router Setup Wizard CD-ROM (English only) or the
instructions in this Fast Start to help you connect the Router, configure your
PCs, and configure the Router.
These instructions will get you up and running quickly using the most basic set-
tings. Once you have access to the Internet, you can get advanced configura-
tion information (for gaming, VPNs, web hosting, etc.) by reading the User
Guide (English only) on the Setup Wizard CD-ROM.

* For information on Uplinking, please refer to the User Guide located on
the Setup Wizard CD-ROM.
Step 1:Connect the Router
In Step 1, you will connect the Router to your cable or DSL modem and to the
computers in your home or business.
First, make sure that all the 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 documentation.)
B. With the Ethernet cable that was used to con-
nect your cable or DSL modem to your PC,
connect your cable or DSL modem to the
Router’s WAN port.

BEFSR11 •If you are connecting the 1-Port Router to just one PC, plug
one end of an Ethernet cable into the Router's LAN port and the
other end into the PC's Ethernet adapter. Set the Crossover
Switch to straight-through (II).
•If you are connecting the 1-Port Router to a hub or switch, plug
one end of an Ethernet cable into the Router's LAN port, and the
other end into to a standard port on your network's hub or switch.
Set the LAN port's Crossover Switch to crossover mode (X).*
If your hub or switch has no more standard ports available, connect
the Router using its LAN port to the Uplink port on the hub or
switch. Set the Crossover Switch to straight-through mode (II) for
this setup.*
Perform these steps:
BEFSX41 or
BEFSR81 •Connect an Ethernet cable to your PC's Ethernet adapter. Connect
the other end of the cable to one of the LAN ports numbered 1-4
or 1-8 on the back of the Router. Repeat this process for every PC
you wish to connect to the Router. For ease of installation, start
with LAN Port 1 and end with Port 4/DMZ or 8.
•If you are connecting more than 4 or 8 PCs to the Router, you
will also need to connect a hub or switch to one of the LAN ports
numbered 1-4 or 1-8 on the back of the Router.*
BEFSR41 •Connect an Ethernet cable to your PC's Ethernet adapter. Connect
the other end of the cable to one of the LAN ports numbered 1-4
on the back of the Router. Repeat this process for every PC you
wish to connect to the Router. For ease of installation, start with
LAN Port 4 and end with Port 1.
•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 1).*

D. Connect to the power adapter to the Router, and
plug it into an electrical outlet. Turn on the
cable or DSL modem.Then turn on the PC you
wish to use to configure the Router.
Proceed to Step 2: Configure the PCs.
8
Step 2:Configure the PCs
In Step 2, you will configure each of your computers to be able to communi-
cate with the Router.
To do this, you need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically (this action is also referred to as DHCP).
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. One way to find out which operating system
you have is by clicking the Start button and then Settings. Click Control
Panel, and then double-click the System icon. If the Start menu doesn’t have a
Settings option, then your PC is running Windows XP. Click the Cancel button
when done.
You may need to do this for each computer you are connecting to the Router.
If your operating system is not referenced here, refer to your operating system’s
documentation.
The next few pages tell you, step by step, how to configure your network set-
tings, depending on the type of Windows operating system you are using. Once
you’ve configured your computers, continue to “Step 3: Configure the Router.”

Step 3:Configure the Router
In Step 3, you will configure the Router so it will be able to access the Internet
through your Internet Service Provider (ISP).You will need the setup informa-
tion provided by your ISP. If you do not have this information, contact your ISP
before proceeding. To find out what questions you should ask your ISP, refer to
Question #1 in the “Help” section.
The instructions from your ISP tell you how to set up your PC for Internet
access. Because you are now using the Router to share Internet access among
several computers, you will use the setup information to configure the Router
instead of your PC.
A. Open your web browser. (It
is all right if you get an error
message at this point.
Continue following these directions.) Enter http://192.168.1.1 in the web
browser’s Address field. Press the Enter key.
B. An Enter Network Password window, shown in Figure B1, will appear
(Windows XP users will see a Connect to 192.168.1.1 window, shown in
Figure B2). Leave the User Name field empty, and enter admin in lower-
case letters in the Password field (admin is the default user name and pass-
word). Then click the OK button.
Note: You only need to configure the Router once using any com-
puter you have set up.
