Verify that the plug to your cable modem gateway AC power is properly
inserted into an electrical outlet.

electrical outlet that is controlled by a wall switch. If a wall switch controls the
electrical outlet, make sure the switch is in the ON position.

cable modem gateway are illuminated.

Verify that TCP/IP is properly installed and configured on all devices if you are
using the Ethernet connections.

If you are using a cable signal splitter so that you can connect the cable signal to
other devices, remove the splitter and reconnect the cable so that the cable

modem gateway now functions properly, the cable signal splitter may be
defective and may need to be replaced.
My cable modem gateway does not register an Ethernet connection
Even new devices do not always have Ethernet capabilities. Verify that your device
has an Ethernet card and that the Ethernet driver software is properly installed. If
you purchase and install an Ethernet card, follow the installation instructions very
carefully.
