• One Quick Installation

1

A

Before you begin, make sure 

that you have the setup infor-

mation for your specific type of 

Internet connection. The instal-

lation technician from your ISP 

should have left this informa-

tion with you after installing 

your broadband connection. If 

not, you can call your ISP to 

request the settings.

B

Make sure that all of your net-

work’s hardware is powered off, 

including the Router, PCs, and 

cable or DSL modem. 

C

Connect one end of an Ether-

net network cable to one of 

the ports (labeled 1-4) on the 

back of the Router, and the 

other end to an Ethernet port 

on a PC. 

D

Repeat this step to connect 

additional PCs or other network 

devices to the Router.

E

Connect a different Ethernet 

network cable from your cable 

or DSL modem to the Internet 

port on the Router’s back 

panel.  This is the only port that 

will work for your modem con-

nection. 

2

Connect the Broadband Router

For Windows 98, Millennium, and XP 

using the default interface, refer to 

the User Guide on the Setup CD-ROM 

or your Windows documentation.

The following instructions apply only 

to Windows 2000 or XP using the 

Classic interface (in which the icons 

and menus look like previous Win-

dows versions).

A

Click the 

Start

 button. Select 

Settings

 and click the 

Control 

Panel

 icon.  Double-click the 

Network and Dial-up

Connections 

icon.

B

Select the 

Local Area Connec-

tion

 icon for the applicable 

Ethernet adapter (usually it is 

the first Local Area Connection 

listed). Double-click the 

Local 

Area Connection

. Click the 

Properties

 button.

C

Make sure the box next to Inter-

net Protocol (TCP/IP) is checked. 

Highlight

 Internet Protocol (TCP/

IP)

, and click the 

Properties 

button.

D

Select 

Obtain an IP address 

automatically

. Once the new 

window appears, click the 

OK

 

button. Click the 

OK 

button 

again to complete the PC con-

figuration, then restart your 

computer.

Proceed to Step 3. 

E

C

Configure the PCs

B

F

Power on the following devices 

in this order: cable or DSL 

modem, Router, and PCs.

G

Connect the AC Power 

Adapter to the Power port and 

the other end into an electrical 

outlet.

H

Make sure the Power and Inter-

net LEDs on the front panel 

light up green.

I

The Power LED will flash green 

for a few seconds when the 

Router goes through its self-

diagnostic test. This LED will stay 

solid when the self-test is com-

plete. If it does not stop flash-

ing, refer to “Appendix A: 

Troubleshooting” of the User 

Guide on the Setup CD-ROM.

Proceed to Step 2. 

D

NOTE:

 

Before setting up the 

Router, make sure your PCs are 
configured to obtain an IP (or 
TCP/IP) address automatically 
from the Router.

IMPORTANT:

Make sure to use 

the power adapter that is sup-
plied with the Router. Use of a 
different power adapter could 
damage the Router.
