Tips for Improved Performance
If your residential gateway does not perform as expected, the following tips may
help. If you need further assistance, contact your service provider.
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
ONLINE
LED status indicator on the front panel of your
residential gateway is illuminated.
Verify that your cable service is active and that it supports two-way service.
Verify that all cables are properly connected, and that you are using the correct
cables.
If you are using the Ethernet connection, verify that your TCP/IP is properly
installed and configured.
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 residential
gateway to other devices, remove the splitter and reconnect the cables so that the
residential gateway is connected directly to the cable input. If the residential
gateway now functions properly, the cable signal splitter may be defective and
may need to be replaced.
If you are connected to your PC with an Ethernet connection, your PC should be
equipped with a Gigabit Ethernet card for best performance.
If your residential gateway has a USB port and you are connected to that port,
verify that you have followed the procedures in Install USB Drivers on Your PC
(Optional).
