My computer has begun telling me that I have limited or no connectivity from my wired connection. I have had this problem once before and fixed it by replacing the network card, but that did not work this time. My roommates’ computers are wireless and are running fine off the router. I have uninstalled and reinstalled the drives. Changed cords, rebooted the router (many times), called the internet provider and they reset the modem and have tried to do system restore but that fails to restore to any prior points as well. Any ideas would be welcome.
