I have an ASUS P7P55D PRO motherboard that I bought in 2009. When I first got the motherboard I installed windows xp professional and everything was fine. I recently upgraded to windows 7 and can't get the ethernet port to work. I can see it on the device manager, I installed and re-installed the drivers several times, I have searched all over for help on this issue and can't seem to find a solution. When I troubleshoot through windows 7 it simply says that the ethernet cable is not plugged in, but I do have the cable plugged in. I also checked the BIOS and everything seems to be fine. Please help me out here...
