Has the Cable Modem's MAC address been registered with your ISP? In
order for your Cable Modem to be operational, you must call and have the
ISP activate the modem by registering the MAC address from the label on
the bottom of the modem.
Make sure that the Coax 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, call your cable company
to verify whether or not a weak signal may be the problem.
All of LEDs on the front of my modem look right, but I still can't access the
Internet.
If the Power LED, Link/Act, and Cable LEDs are on but not blinking,
your cable modem is operating properly. Try shutting down and powering
off your computer and then turning it back on. This will cause your com-
puter to re-establish communications with your Cable ISP.
Try pressing the Reset button on the back of your cable modem. Using an
object with a small tip, push the button until you feel it click. Then try
reconnecting to your Cable ISP.
Make sure that TCP/IP is the default protocol in use by your system. See
the section called Installing the TCP/IP Protocol for more information.
The power on my modem goes on and off sporadically.
You may be using the wrong power supply. Check that the power supply
you are using is the one that came with your Cable Modem.
