Now that you’re familiar with the 

Router, follow these instructions for 

quick installation.

A

Before you begin, make sure 

that all of your hardware is 

powered off, including the 

Router, PCs, hubs, switches, 

and cable or DSL modem.

B

Connect one end of an Ether-

net network cable to one of the 

numbered ports on the back of 

the Router. Connect the other 

end to an Ethernet port on a 

network device, e.g., a PC, 

print server, hub, or switch.

Repeat this step to connect 

more PCs or other network 

devices to the Router.

C

Connect your cable or DSL 

modem’s Ethernet cable to the 

Router’s Internet port.

D

Power on the cable or DSL 

modem.

E

Connect the included power 

adapter to the Router’s Power 

port, and then plug the power 

adapter into an electrical out-

let. 

The Power LED on the front 

panel will light up as soon as 

the power adapter is con-

nected properly.

Power on the Router, PCs, hubs, 

and switches.

Getting to know 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.

B

Connect the Router

The Back Panel

The Router’s ports and the Reset but-

ton are located on the back panel 

of the Router.

Internet This port connects to your cable or DSL 

modem.

These four ports connect to network 
devices, such as PCs, print servers, or 
additional switches.

If the Router is having problems connecting 

to the Internet, press the Reset button for 
just a second with a paper clip or a pencil 
tip, which is similar to rebooting your PC.
If you are experiencing extreme problems 
with the Router and have tried all other 
troubleshooting measures, press and hold 
in the Reset button for 30 seconds. This will 
restore the factory defaults and clear all of 
the Router’s settings, such as port 
forwarding or a new password.

This port is where you will connect the 

power adapter.

B

The Front Panel

The Router’s LEDs, which inform you 

about network activities, are located 

on the front panel.

Green. This LED lights up when the Router 
is powered on and flashes when the Router 
is running a diagnostic test.

Green. This LED lights up when DMZ is 
used.

Ethernet Green. This LED shows when the Router is 

connected to a device through the 
corresponding port (1, 2, 3, or 4) and 
flashes when the Router is sending or 
receiving data over that port.

Internet Green. This LED lights up when the Router 

is connected to your cable or DSL modem.

NOTE:: Make sure your PC’s Ethernet

automatically. For more information, 
refer to Windows Help.
