The Online LED never stops flashing.

Go through this checklist until your problem is solved:

Make sure the Cable Modem’s MAC address has been registered with

your cable ISP. In order for the Cable Modem to work, you must call

and have the ISP activate the Cable Modem by registering its MAC

address. You can find the modem MAC address on a label located on

the Cable Modem’s bottom panel.
Make sure the coaxial cable is firmly attached between the Cable

Modem and the wall jack.
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.

All of the LEDs on the Cable Modem indicate that the Cable Modem is

functioning properly, but you still cannot access the Internet.

Go through this checklist until your problem is solved:

If the Power, DS, US, 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. When the Online LED is solidly lit, try to connect to the

Internet again.
Make sure TCP/IP is the default protocol used by your computer. For

more information, refer to Windows Help.

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.
