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 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 outlet.
Caution: Be sure to use only the power adapter that came with the cable modem.
Using the wrong power adapter can damage the cable modem. If you must replace the
power adapter, contact your local cable provider for assistance.
Cable LED is not lit or keeps blinking Orange
Possible reason: The cable modem cannot detect any carrier or valid data channel from the
coaxial cable.
Action: Make sure the connectors at each end of the coaxial cable are securely seated. If the
problem persists, please contact your cable modem service provider for further assistance.
The quality of CATV coaxial cable and installation can affect the connection dramatically.
Cable LED not lit or stays Orange
Possible reason: The cable modem can not range the upstream signal properly with the
Cable Headend system .
Action: Please make sure the connectors at each end of the coaxial cable are securely
seated. If the problem still persists, contact your cable modem service provider for further
assistance.
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, Windows
NT, Windows 2000, Windows Me, Windows XP, 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 is for 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.
