Troubleshooting
Nothing happens when I press the on/off button.
•Make sure that the AC adapter is fully plugged into a wall outlet.
•Make sure that the power supply cord is fully inserted into the AC adapter
connection on the back of the modem.
•Double-check that the AC outlet you are using is not controlled by a light
switch that is turned off.
All of the lights are flashing simultaneously.
•This means the cable modem is automatically updating its system software.
Please wait for the lights to stop flashing. The updating process typically lasts
less than one minute.
•Do not remove the power supply or reset the cable modem during this process.
The light labelled “email” is flashing.
•This means you have new mail to check.
I can’t get the modem to register an ethernet connection.
•Even new computers don’t always have ethernet capabilities – be sure to verify
that your computer has a properly installed ethernet card and ethernet driver
software.
The modem won’t register a cable connection.
•The modem should work with a standard coaxial cable, but if you’re using a
cable other than one your cable company provided along with the cable
modem, it may be the wrong one. Check with your cable company to determine
whether you’re using the correct cable.
