Tips for Improved Performance
Tips for Improved Performance
Check and Correct
If your cable modem 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 cable modem gateway AC power is properly
inserted into an electrical outlet.
Verify that your cable modem 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 ONLINE LED status indicators on the front panel of
your cable modem gateway are illuminated.
Verify that all cables are properly connected, and that you are using the correct
cables.
Verify that your service is active and that it supports two-way service.
Verify that your TCP/IP is properly installed and configured if you are using the
Ethernet connection.
Verify that you have followed the procedures in How Do I Install USB Drivers?
(on page
26), if you are using the USB connection.
Verify that you have called your service provider and given them the serial
number and MAC address of your cable modem gateway.
If you are using a cable signal splitter so that you can connect the cable modem
gateway to other devices, remove the splitter and reconnect the cables so that the
cable modem gateway is connected directly to the cable input. If the cable
modem gateway now functions properly, the cable signal splitter may be
defective and may need to be replaced.
For best performance over an Ethernet connection, your PC should be equipped
with a 10/100BaseT network interface card.
