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 cable
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.
Frequently Asked Questions
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, data service may be made available with
or without subscribing to cable TV service. Contact your local cable service
provider for complete information on cable services, including high-speed
Internet access.
Q. How do I arrange for installation?
A. Call your cable telephony service provider to inquire about professional
installation. A professional installation ensures proper cable connection to the
modem and to your PC, and ensures proper configuration of all hardware and
software settings. Contact your cable telephony service provider for more
information about installation.
Q. How does the cable modem connect to my computer?
A. The cable modem connects to the USB port or the 10/100BaseT Ethernet
port on your PC. If your PC is not equipped with an Ethernet interface, an
Ethernet card is available from your local PC or office supply retailer, or from
your cable service provider.
