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 switch
that is turned off.
All of the lights are flashing in sequence.
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.
The light labelled "email" does not flash.
This may mean that your service provider does not offer this feature.
I can't get the modem to establish 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 the driver
software to support it.
Check to see that you are using the right type of Ethernet cable (see page 6).
The modem won't register a cable connection (Cable light not on
continuously).
If the modem is in Initialization Mode, the Power Light will be flashing. Call
your Cable company if it has not completed this 5-step process within 30
minutes, and note which step it is getting stuck on. See page 8 for details.
The modem should work with a standard RG-6 coaxial cable, but if you're using
a cable other than one your cable company recommends, or if the terminal
connections are loose, it may not work. Check with your cable company to
determine whether you're using the correct cable.
If you subscribe to video service over cable, the cable signal may not be
reaching the modem. Confirm that good quality cable television pictures are
available to the coaxial connector you are using by connecting a television to
it. If your cable outlet is "dead" call your Cable company.
Verify that the cable modem service is DOCSIS-compliant by calling your cable
provider.
I can't access the internet or my email
Check all of the connections to your cable modem.
Your Ethernet card may not be working. Check it's documentation for more
information.
The Network Properties of your operating system may not be installed correctly
or the settings may be incorrect. Check with your ISP or cable company.
