I have experienced this many times. Cable modems don't continually give out ip address's, they only give them shortly after being powered on and become ready. Click start, click run, type cmd and click okay. (this should give you a command prompt) Type ipconfig and press enter, this will show you your current IP address. If it starts with 169, then windows isssued itself an IP because nothing gave it an IP. Type ipconfig /release, this will release your IP (there is a space behind ipconfig and before the /) Hit enter. Now type ipconfig /renew, but don't press enter yet. Power off your cable modem, wait 5 seconds, then turn it on. It will go through a self test, then come ready. As soon as it comes ready press enter, you may have to try several times. Type ipconfig and see if it gave you a new IP. Good Luck.
It still could be a bad cable modem or your network card could be bad, but lets not assume that just yet.
