6.4 Troubleshooting the USB driver Installation
Q: None of the LEDs is on when I power on the LAN Cable Modem.
A: Check the connection between the power adapter and the cable modem. Power off the Cable
Modem and wait for 5 Seconds and power on the modem again. If the problem still exists, you
may have a hardware problem.
Q: All of the LEDs on the front of my modem look correct, but I cannot access the Internet.
A:
• If the POWER, DS, US and Online are solidly lit, the cable modem is working properly.
Use the following procedures to verify connectivity between the PC and the cable modem:
1. Launch Your PC’ Internet Browser (e.g., Netscape, IE)
2. Enter http://192.168.100.1
into your browser. This URL connects you directly to the
web server within your cable modem. A successful connection indicates that the PC is
able to communicate with the cable modem. The next step is to enter a public URL to
ensure connectivity between the cable modem and your cable service provider. If this
fails, please contact your cable service provider for further assistance.
• Try restarting the computer so that it could re-establish a connection with the cable modem.
• Power cycle the cable modem by removing the power adapter from the electrical outlet and
plugging it back in. Wait several minutes for the cable modem to re-establish
communications with your cable service provider.
• Remove any other USB devices from your computer and connect the cable modem’ USB
cable directly to the USB port on your computer.
• If you are using a cable splitter, try removing the splitter and connect the cable modem
directly to the cable wall outlet. Wait several minutes for the cable modem to re-establish
communications with your cable service provider.
• Your USB or coaxial cable may be damaged. Try using another cable.
• If none of these suggestions work, contact your cable service provider for further assistance.
