Verify that the plug to your residential gateway AC power is properly inserted

into an electrical outlet.
Verify that your residential gateway AC power cord is not plugged into an

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.
Verify that the POWER and CABLE indicator lights on the front panel of your

residential gateway are illuminated.
Verify that the indicator lights on your router or other network connection

equipment are illuminated
Verify that all cables are properly connected, and that you are using the correct

cables.
Verify that your cable service is active and that it supports two-way service.

Verify that TCP/IP is properly installed and configured on all devices if you are

using the Ethernet connections.
Verify that you have called your service provider and given them the serial

number and MAC address of your residential gateway.
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 residential
gateway is connected directly to the main cable input. If the residential gateway
now functions properly, the cable signal splitter may be defective and may need
to be replaced.
For best performance over an Ethernet connect, your PC should be equipped

with a 10/100BASE-T network interface card.
My residential gateway does not recognize the cable network
The residential gateway works with a standard, 75-ohm, RF coaxial cable. If you are
using a different cable, your residential gateway will not function properly. Contact
your service provider to determine if you are using the correct cable.
