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.

Having Difficulty?
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.
Q. After my cable modem is connected, how do I access the Internet?
A. Your local service provider becomes your Internet Service Provider (ISP). They
offer a wide range of services including e-mail, chat, news, and information services.
Your cable service provider will provide the software you will need.
Q. Can I watch TV and surf the Internet at the same time?
A. Absolutely! If you subscribe to cable television service, you can watch TV and
use your cable modem at the same time by connecting your TV and your cable
modem to the cable network using an optional cable signal splitter.
Q. Can I run more than one device on the modem?
A. Yes. A single cable modem will theoretically support up to 253 Ethernet devices
utilizing user-supplied Ethernet hubs or routers that you can purchase at your local
PC or office supply retailer. Another user at your location can simultaneously
connect to the USB port on the cable modem. Contact your service provider for
further assistance.
