Troubleshooting

The 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?
Model CM900S only: Is the rear panel power switch in the ON position?
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 Cable Modem, especially when many people are online. Al-
ways leave your Cable 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 be either on or blinking.
• If the Power light blinks for more than 30 minutes, call your cable com-
pany for assistance.
Check your cable connections. Connectors should be tight. The
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 Cable Modem and CATV outlet, remove
the splitters and connect the Cable Modem directly to the outlet.
Proceed to the Ethernet solution (next page) if necessary.
