Congratulations! Thank you for choosing the Linksys EtherFast®Cable/DSL Firewall
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 (WideArea 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.
B. Using the Ethernet cable that came with your cable
or DSL modem, connect the LAN or Ethernet port of
the cable or DSL modem to the WAN 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 Ethernet
adapter’s user guide for more information.
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 more 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 refer to the User
Guide located on the Setup Wizard CD-ROM.
D. Connect the power adapter to the Router. Connect
the power adapter to the electrical outlet. Turn on
the cable or DSL modem. Then turn on the first PC
you wish to use to configure the Router.
Proceed to Step 2: Configure 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, make sure that all devices you’ll be working with are powered down,includ-
ing 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
(FigureA2). (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 asWindows 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 runningWindows XP. Click theCancel 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.
A. Go to the Network screen by clicking the
Start button. Click Settings and then Control
Panel. From there,double-click the Network
icon.
B. On the Configuration tab, select the TCP/IP
line for the applicable Ethernet adapter*. If
the word TCP/IP appears by itself,select that
line.** Click the Properties button.
C. Click the IP Address tab. Select Obtain an IP
address automatically.
D. Now click the Gateway tab to ensure that the
Installed Gateway field is left blank. Click the
OK button.
E. Click the OK button again. Windows may ask
you for the original Windows installation disk
or additional files. Supply them by pointing to
the correct file location, e.g., D:\win98,
D:\win9x, c:\windows\options\cabs, etc. (if
“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: Ifthere is noTCP/IP linelisted,refer tothe User Guide found on the Setup
Wizard CD-ROM or your Ethernet adapter’s user guide to install TCP/IP now.
A. Go to the Network screen by clicking the Start
button. Click Settings and then Control
Panel. From there, double-click the Network
and Dial-up Connections icon.
B. Select the Local Area Connection icon for
the applicable Ethernet adapter (usually it is
