Basic Modem Configuration

The first time you setup the Modem it is recommended that you configure the WAN connection using a single computer
connected directly to the Modem. Once the WAN connection is functioning properly, you may continue to make
changes to Modem configuration including IP settings and DHCP setup. For information on how to configure advanced
features such as port redirection, filtering, and firewall, please skip ahead to the Advanced Modem Management section
on page 32.
Configuration Summary
1. Connect to the Modem To configure various settings used by the Modem for Internet and access it is first
necessary to access the Modem's management HTML-based interface. This is done using an ordinary web
browser. Your computer must be able to "see" the Modem before it can manage it using a browser. If the
Modem is in the same "neighborhood" or subnet as the Modem, you should be able to access the management
software. Therefore you must first make sure your computer has IP settings that place it in the same subnet as
the Modem. The easiest way to make sure your computer has the correct IP settings is to configure it to use the
DHCP server in the Modem. The DHCP server will automatically enable your computer to use a browser to
manage the Modem. The next section describes how to change the IP configuration for a computer running a
Windows operating system to be a DHCP client. If you are running another operating system, make sure your
computer is configured as a DHCP client so it can automatically obtain IP settings from the Modem. Some
operating systems will automatically select the best IP settings. Consult the user manual for the operating
system (OS) if you are unsure.
2. Configure the Internet (WAN) Connection Most users will be able to complete this process using the Setup
Wizard. The Setup Wizard can be launched once you have successfully connected with the Modem's
management software. There are different methods used to establish the WAN connection to the service
provider's network and ultimately to the Internet. Your Modem may already have most of the settings
configured by default. However you will probably at least have to type in a user name and password given to
you by your ISP. You may also need to know the encapsulation and connection type required to use for your
ADSL service. Your service provider should provide all the information needed to configure the WAN
connection.

Computer IP Settings

In order to configure your system to receive IP settings from the Modem your computer must first have the TCP/IP
protocol installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If
you are using Windows XP the TCP/IP is enabled by default for standard installations. Instructions for configuring your
computer to receive IP settings from the Modem are provided in Appendix B on page 48.
For computers running non-Windows operating systems, follow the instructions for your OS that configure the system
to receive an IP address from the Modem, that is, configure the system to be a DHCP client.
If you are not sure how to configure your Windows computer to be a DHCP client, see
Configuring IP Settings on Your Computer beginning on page 48.
