First Time Set Up 

Now that the Modem is powered on and connected to your computer you are ready to proceed to the next step. 

However, before going further, make certain you have a valid link to the Modem. You can check this by looking 

at the Ethernet Link LED indicator on the front panel of the Modem. If the LED is green you have a link, if it is 

dark, check both ends of the cable to make sure it is firmly connected to the Modem and your computer’s 

Ethernet port. 

A valid Ethernet link means that your computer is physically linked to the Modem, however, you will not to able 

to access the web-based configuration manager until the computer can “see” the device. In order to see the 

Modem both your computer and the Modem must be in the same IP “neighborhood” or subnet on your local area 

network (LAN). You will need to check the IP settings of your system and, if necessary, change them so the 

computer and Modem are in the same subnet. Follow the instructions in this chapter to configure the IP settings 

of your system. 

For some Modem users, it will not be necessary to change any settings on the Modem for the device to work 

properly. If you received a CD with software for your computer, the Modem may be ready to use. Follow the 

instructions of your service provider regarding any connection software for your computer. If you need to 

configure the VPI, VCI or other connection settings, read the section titled ATM VC Configuration in the next 

chapter on page 16. 

The first time you set up the Modem it is best to first establish the ADSL connection using one non-networked 

computer. This way you can verify that the ADSL service is functioning and that you are able to communicate 

with the device. Once the initial ADSL connection is established, you can connect the device to the Ethernet 

LAN. 

IP Settings 

To access the Modem’s management software that uses a web-based (HTML) interface for configuration, you 

will probably have to change the LAN IP settings of your computer. The LAN IP settings are what your browser 

uses to find and communicate with the Modem. The Modem has a default IP address of 10.1.1.1 and a subnet 

mask of 255.0.0.0 these numbers are the LAN IP settings of the Modem. You will need to change the IP settings 

on your computer so the IP address is 10.1.1.10 and the subnet mask is 255.0.0.0. If you do not know how to 

change IP settings for your operating system, read the following section or consult the Help directory or the 

user’s guide included with your system.
