Tips for Improved Performance
If your cable modem 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 AC power is properly inserted into an
electrical outlet.
Verify that your cable modem 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 cable
modem 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 cable modem.
If you are using a cable signal splitter so that you can connect the cable modem
to other devices, remove the splitter and reconnect the cables so that the cable
modem is connected directly to the cable input. If the cable modem 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.
