Linksys highly recommends that you 

use the Setup CD-ROM to install the 

Cable/DSL Router with 8-Port Switch. 

However, if you prefer to install the 

Router manually, then follow the 

instructions in this Quick Installation.

A

Make sure all devices, includ-

ing your PCs, modem, and 

Router, are powered down. 

B

If you haven’t already done so, 

connect your cable or DSL 

modem to its proper connec-

tion—the coaxial jack for 

cable or the phone jack for 

DSL. Follow the instructions from 

your cable or DSL modem’s 

installation guide. 

C

Using an Ethernet network 

cable, connect the LAN or 

Ethernet network port of the 

cable or DSL modem to the 

Router’s Internet port.

D

Connect an Ethernet network 

cable to your PC’s Ethernet 

network adapter.

E

Connect the other end to one 

of the Router’s Ethernet ports. 

2

Connect the Router

In Step 3, you will need the setup 

instructions provided by your Inter-

net Service Provider (ISP). If you do 

not have this information, then con-

tact your ISP before proceeding.

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 config-

ure the Router instead of your PC.

A

Open your PC’s web browser. 

Enter http://192.168.1.1 (the 

Router’s default local IP 

address) in the web browser’s 

Address field. Then press the 

Enter key.

B

A screen will appear and ask 

you for a User Name and Pass-

word. Leave the User Name 

field empty, and enter admin 

(the default) in the Password 

field. Then click the OK button.

C

The Router’s Web-based Utility 

will appear with the Basic Setup 

screen showing.

H

B

Configure the Router

E

A

F

Repeat Steps D and E for every 

PC you wish to connect to the 

Router.

If you are connecting more 

than eight PCs to the Router, 

then you will need to connect 

a hub or switch to any of the 

Router’s Ethernet ports.

G

Power on the cable or DSL 

modem, and power on the PC 

you wish to use to configure 

the Router.

H

Connect the included power 

adapter to the Router.

I

Connect the other end of the 

adapter to an electrical outlet.

adapter is set to obtain an IP address 
automatically. For more information, 
refer to Windows Help.
