Configuration
Usage
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.
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
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.
