Troubleshooting

The Telephony Modem is plugged in, but the
Power light is Off
Check all power connections. Is the power cord plugged in firmly at both ends?
If you plugged the power cord into a power strip, make sure the strip is switched on.
Try to plug the power cord into a different outlet. If the outlet is controlled by a wall switch,
make sure the switch is on.
Finally, check the fuse or circuit breaker panel.

I'm not getting on the Internet

It may take over 30 minutes to establish a connection the first time you power up your
Telephony Modem, especially when many people are online. Always leave your Telephony
Modem plugged into AC power and connected to the cable system.
Check the front panel lights:
The Power and Online lights should be on.

The Link light should either be on or blinking.

If the Power light blinks for more than 30 minutes, call your service provider for

assistance.
Check your cable connections. Connectors should be tight. The coax cable should not be
pinched, kinked, or bent sharply—any of these can cause a break or short in the cable (you
may have to replace the cable). If you have one or more splitters between the Telephony
Modem and CATV outlet, remove the splitters and connect the Telephony Modem directly
to the outlet.
Proceed to the Ethernet solution if necessary.

I'm not getting on the Internet (Ethernet)

If you are using a hub, is the hub turned on?
Are you using the right type of Ethernet cable? Use the supplied cable for direct connection
to a computer; use a cross-over cable for connection to a hub.
