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 mul-
tiplayer 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 glob-
al, covers 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 are con-
nected 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.
Then the Router is 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 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 settings.
Once you have access to the Internet, you can get advanced configuration informa-
tion (for gaming, VPNs, web hosting, etc.) by visiting our website at
support.linksys.com or by reading the User Guide on the Setup Wizard CD-ROM.

This is What You Will Be Setting Up
You may have different computers than what are pictured here, but the setup is sim-
ilar. The Router lets you share your fast cable or DSL connection among several com-
puters 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 desktop
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.

Step 1: Connect the Router
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, make sure that all devices you'll be working with are powered down, includ-
ing your PCs, modem, and 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 Ethernet
adapter's user guide for more information.

Note: For ease of installation, start with LAN Port 4, then Port 3, then Port 2, and
finally Port 1.
If you are connecting more than four PCs to the Router, you will need to connect
a hub or switch to the Uplink port of the Router (if you use the Uplink port, then
you cannot use Port 1). Please refer to the User Guide located on the Setup
Wizard CD-ROM.
