Connect the included power 

adapter to the Router’s Power 

port, and then plug the power 

adapter into an electrical 

outlet. 

The Power LED on the front 

panel will start flashing as soon 

as the power adapter is 

connected properly. This LED 

will continue to flash while the 

Router is booting up.

G

When the Power LED stops 

flashing and is solidly lit, power 

on the PC you wish to use to 

configure the Router.

In Step 2, you will need the setup 

instructions provided by your high-

speed Internet service provider. If 

you do not have this information, 

then contact your high-speed 

Internet service provider before 

proceeding.

These instructions 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 

configure the Router instead of 

your PC.

A

Open your PC’s web browser. 

Enter http://192.168.15.1 (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 

Password. Leave the User 

Name field blank, and enter 

admin (the default) in the 

Password field. (Later you 

should set a new password 

using the Administration tab’s 

Management screen. This will 

help secure access to the 

Web-based Utility.) 

Then click the OK button.

C

The Router’s Web-based Utility 

will appear with the Basic Setup 

screen showing.
