Troubleshooting

The Wideband Cable 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.

Avoid using an outlet controlled by a wall switch, if possible.

Check the outlet by plugging in another device (such as a lamp).

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 Wideband Cable Modem, especially when many people are

online. Always leave your Wideband Cable Modem plugged in and connected

to the cable system.

Check the front panel lights:

• The Power and Online lights should be on.

• The Link light should be either on or blinking.

• The DS and US lights should be on.

• If the Power light blinks for more than 30 minutes, call your cable com-

pany for assistance.

Check your cable connections. Connectors should be ﬁnger-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 Wideband Cable Modem and CATV

outlet, remove the splitters and connect the Wideband Cable Modem directly

to the outlet.

Proceed to the Ethernet or USB solutions (next page) if necessary.
