I don't understand the front panel status indicators

See Front Panel LED Status Indicator Functions (on page 106), for more detailed information on front panel LED status indicator operation and function.

The modem does not register an Ethernet connection

Verify that your computer has an Ethernet card and that the Ethernet driver software is properly installed. If you purchase and install an Ethernet card, follow the installation instructions very carefully.

Verify the status of the front panel LED status indicators.

The modem does not register an Ethernet connection after connecting to a hub

If you are connecting multiple PCs to the residential gateway, you should first connect the modem to the uplink port of the hub using the correct crossover cable. The LINK LED of the hub will illuminate continuously.

The modem does not register a cable connection

The modem works with a standard 75-ohm RF coaxial cable. If you are using a different cable, your residential gateway will not function properly. Contact your service provider to determine whether you are using the correct cable.

Verify that you have followed the procedures in How Do I Troubleshoot My Internet Service Installation? (on page 96).
