The Broadband Router can easily be connected to any Ethernet-based cable or DSL
modem. To verify compatibility, look at the existing connection between your modem and
your computer. If the connection is made with an RJ-45 Ethernet cable, your modem can
be connected to the Broadband Router.

What You Need to Begin

• PC with an Ethernet adapter (NIC) installed

• A functioning Ethernet-based cable or DSL modem

• Internet Explorer 5.0 or later
OR
Netscape 7.0 or later

• Your CD-ROM drive letter (for example, D)

• Your router product number and serial number, located on the bottom label of the router.
If you ever need to call our Technical Support department, you will need this number to
receive assistance.

1. Connect one end of the supplied Ethernet cable to your
PC’s Ethernet adapter.

2. Connect the other end to one of the router’s LAN ports.

3. Turn on your modem.

4. Connect the supplied power adapter to the power jack
on the router.

5. Plug the power adapter into a standard power outlet.

6. Turn on your computer.
