Having Difficulty?

If your cable modem gateway does not operate as expected, the following troubleshooting tips may help. If you
need further assistance, contact your cable service provider.

My cable modem gateway does not register a cable connection.

The cable modem gateway works with a standard, 75-ohm, RF coaxial cable.

If you are using a different cable, your cable modem gateway will not function
properly. Contact your cable service provider to determine whether you are
using the correct cable.

Verify that the plug to your cable modem gateway AC adapter is properly

inserted into an electrical outlet.

Verify that your cable modem gateway AC adapter is not plugged into an

electrical outlet that is controlled by a wall switch. If a wall switch controls the
electrical outlet, make sure the switch is in the ON position.

Verify

that

the

Power

and Cable indicators on the front panel of your cable

modem are illuminated.

Verify that all cables are properly connected.

Verify that your cable service is active and that it supports two-way service.

Verify that you have called your cable service provider and given them the

serial number and MAC address of your cable modem gateway.

If you are using a cable signal splitter so that you can connect the cable

modem gateway to other devices, remove the splitter and reconnect the
cables so that the cable modem gateway is connected directly to the cable
input. If the cable modem gateway now functions properly, the cable signal
splitter may be defective and may need to be replaced.

There is no dial tone when I lift the telephone handset.

You may be using the wrong phone cable to connect the HPNA port on the

cable modem gateway to your wall telephone jack. Try a different phone
cable.

There may be a problem with your home telephone wiring. A professional

may need to diagnose and repair a problem with your telephone wiring.

There may be a problem with your telephone set. Use a different telephone

set and listen to hear dial tone.
