Common Troubleshooting Issues
I don't understand the front panel status indicators
See Front Panel LED Status Indicator Functions, 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 residential gateway, you should first
connect the modem to the uplink port of the hub using the correct crossover cable.
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 residential gateway will not function properly. Contact your
service provider to determine whether you are using the correct cable.
Verify that you have followed the procedures in How Do I Troubleshoot My Internet
Service Installation?.
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

residential gateway. The residential gateway 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.
