Troubleshooting

If the cable modem is not working properly, please follow the procedures below to solve the problem.

1.Check to verify that all equipment is powered “ON” and the cable connections are secure.

2.Check the cable modem to see if the LED lights function properly.

Power LED is not lit

Action: Check both ends of the power adapter to make certain that they are securely connected to the power jack on the cable modem and the power outlet.

If both ends of the power adapter are properly connected and there is still no power, the cable modem might have a faulty power adapter or electrical outlet. Try plugging the power adapter into a different electrical wall outlet.

Be sure to use only the power adapter that came with the cable modem. Using the wrong power adapter can damage the cable modem and will void your warranty.

Status LED is on, but the computer fails to get the IP address and cannot connect to the Internet

Possible reasons: The driver for the network interface card has not been installed or was not installed properly. Please refer to the instruction of the operating system (Windows 95, Windows 98/98SE, Windows NT, Windows 2000, Windows Me, NetWare, etc.) and the user documentation of the network interface card to have the network interface card installed properly.

In order to access the Internet through the CATV Headend, which acts as an ISP (Internet Service Provider), your computer must have the right TCP/IP setting. Set the TCP/IP setting of the network interface card to get the IP address from the ISP automatically using DHCP protocol. For more information, please contact your local cable modem service provider.

The Ethernet port LED of the connected device is not lit

Action: Check if the device being connected is powered “ON”, operating correctly, and properly connected. Also check if the cable is [straight-through] for an end device like a PC/notebook. If the cable will be connecting to a hub or switch port, you should use [crossed] wire instead. Make sure the connectors at both ends of the cable are securely seated. If the problems continue, it is possible that the cable you are using is not compliant with specifications, or is improperly connected or damaged.
