Hey Guys, I'm trying to get my new HTPC up and running but having an issue with networking. Its running Windows 7 (RC 7127) on an Asus M3N78-EM motherboard with an nForce network controller. I plug the ethernet patch lead in and it says the Network cable is unplugged. I tried plugging a crossover cable, from the new computer to my laptop which worked fine. The computers could see eachother - lights were flashing and files were transferring nice and quick., so thought it might be the cable. Today I went out to buy a new patch lead, and i'm still getting the same problem - it keeps saying Network cable unplugged. I'm trying to connect it to my DLINK DSL-G604T router which all the other computers connect to without a problem. I just checked Device Manager and it had 2 devices that weren't found One was a 'co processor' which turned out to be the nForce System Management Controller, that is now installed. The other shows up as 'unknown device' which it cant find on my driver disc so not sure what it is Successfully updated all the drivers with the new nForce Win7 X64 drivers (15.37) It updated my ethernet adapter which now reads "NVIDIA nForce 10/100/1000 Mbps Ethernet" but still no luck with sensing the cable. I've also tried forcing it to 100mbps full duplex with no luck either. Now when I try to run diagnosis it displays The "Local Area Connection" is experiencing driver or hardware related problems. Can anyone else help me with what could be causing this problem?!?
