Troubleshooting
Troubleshooting
If the cable modem is not working properly, please follow the proce-
dures 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 dam-
age the cable modem. If you must replace the power adapter,
contact your local cable provider for assistance.
USB LED not lit
Possible reason: The USB cable is not connected properly or the
USB driver is not installed properly.
Action: Check if the device being connected is powered on, oper-
ating correctly and properly connected. Make sure your operating
system does support USB device and installed with the driver
provided with the installation CD. Right now the supported opera-
tion systems include Windows 98SE, Windows 2000, Windows Me
and Windows XP.
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 pos-
sible that the cable you are using is not compliant with
specifications, or is improperly connected or damaged.
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.
Troubleshooting (cont.)
Status LED is on, but the computer fails to get the IP ad-
dress 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.
