Common Troubleshooting Suggestions
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.
