I don't understand the front panel status indicators

See Front Panel LED Status Indicator Functions (on page 34), 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 cable modem, you should first connect the modem to the uplink port of the hub. 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 cable modem will not function properly. Contact your service provider to determine whether you are using the correct cable.

There is no dial tone when I lift the telephone handset

Your telephone wiring may be connected to the wrong RJ-11 port on the cable modem. The cable modem has two telephone ports. Verify that you are connected to the correct telephone port.

There may be a problem with your telephone set. Use a different telephone set and listen to hear dial tone.

There may be a problem with your home telephone wiring. Use a telephone and connect directly to the same RJ-11 port on the back of the unit. If the dial tone is working here but does not work at other locations in the home, a professional may need to diagnose and repair a problem with your telephone wiring.

Verify that the phone company has removed the previous telephone service from your home telephone wiring.

Your telephone service may not be enabled from your cable telephony service provider. Contact your cable telephony service provider for more information.
