If the Cable Link LED does not light when connected to your cable television cable, check the 
following:

•

Make sure that the coaxial cable connections are secure at the gateway and at the wall jack.

•

Make sure that your cable internet service has been provisioned by yor cable service provider. 
Your provider should verify that the signal quality is good enough for cable modem service.

•

Remove any excessive splitters you may have on your cable line. It may be necessary to run a

169.254.x.x. If your IP address is in this range, check the connection from the PC to the 
gateway and reboot your PC.

•

If your gateway’s IP address has been changed and you don’t know the current IP address, 
clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to 
192.168.0.1. This procedure is explained in
