Most problems with cable come from not resetting the cable modem when changing the device connected to it.  To reset, you have to turn everything off, wait about 5 minutes, turn on the modem first, wait another 2 or 3 minutes, then turn on the computer.  If you change network cards in the computer, this has to be done as well because the modem would detect it as a different device and will never connect to a different device until the reset procedure is done.

Did that several times, I keep getting the message on the repair,  Windows could not finish repairing the problem because the following action cannot be completed

Renewing your IP address

Did all thats been mentioned, still no internet, its the same cable that I'm using for this computer, thru a linksys router, is it possible that the motherboard could be damaged, just a thought because everything else points to it should be working.

Assuming you are running Windows XP on the problem machine, try downloading and running winsockfix for Windows XP from the Here

Tried the last, still no cable connection, this is frustrating, one more thing, at bootup I get the message  Plug and Play error. hit f-1 to continue or go to setup, have gone to setup and find nothing wrong, have pulled the card and replaced it a dozen time rebooting the modem and computer with no results.  It control panel it still tells me it should be working and I have reinstalled windows to.

To help troubleshoot this problem, on the computer with the problem, go to Start > Run and type cmd then click OK. In the command prompt window that opens, type ipconfig /all then hit the enter key. Write down the output from this command or select it and save it to a txt file, then copy this output into a reply to this message.  Maybe this will give us a clue as to what is going on here.
