Common Problems and Solutions
Cable Modem with USB and Ethernet Connections
The signal from your cable company’s equipment may be too weak or the cable line may not be properly
attached to the Cable Modem. If the cable line is properly connected to the Cable Modem, then call your
cable company to verify whether a weak signal may be the problem.
3. All of the LEDs on the Cable Modem indicate that the Cable Modem is functioning properly, but I still
can’t access the Internet.
Go through this checklist until your problem is solved:
If the Power and Online LEDs are lit but not flashing, then the Cable Modem is operating properly. Power
your computer off and back on again. This will cause your computer to re-establish communications with
your cable ISP.
Press the Reset button on the back panel of the Cable Modem. Using an object with a small tip, such as a
pen, push the button until you feel it click. Then try reconnecting to the Internet.
Make sure TCP/IP is the default protocol used by your computer. For more information, refer to “Appendix
B: Windows Help.”
4. The power on the Cable Modem goes on and off sporadically.
You may be using the wrong power adapter. Make sure the power adapter you are using is the one included
with the Cable Modem.
