Quick Start Guide

The modem does not register a cable connection.
The modem works with a standard, 75-ohm RF coaxial cable. If you are using a different cable, your
modem will not function properly. Contact your service provider to determine whether you are using
the correct cable.
Tips for improved performance
Check and correct
If your modem does not perform as expected, the following tips may help. If you need more help,
contact your service provider.
•
Verify that the plug to your modem’s AC power is connected to a power source.
•
If your modem’s AC power cord is plugged into an electrical outlet that is controlled by a wall
switch, make sure the switch is turned on.
•
Verify that the modem’s Ethernet LED status indicator is on.
•
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 modem.
•
If you are using a cable signal splitter so that you can connect the modem to other devices,
remove the splitter and reconnect the cables so that the modem is connected directly to the
cable input. If the modem now functions properly, the cable signal splitter may be defective
and may need to be replaced.
•
If you are connected to your computer with an Ethernet connection, your computer should be
equipped with a Gigabit Ethernet card for best performance.
