contact technical support.
• Make sure that the Ethernet cable connections are secure at the
gateway and at the hub or PC.
• Make sure that power is turned on to the connected hub or PC.
• Be sure you are using the correct cable:
• When connecting the gateway's Internet port to a cable or DSL
modem, use the cable that was supplied with the cable or DSL
modem. This cable could be a standard straight-through Ethernet
cable or an Ethernet crossover cable.
• 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
your 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 "home run" back to the point where the
cable enters your home.
