Hi all, I have a PC that I built with an Asus P8Z68-V PRO motherboard and I just bought the Negear WNDR4500 router. I am unable to connect to the PC to the router at a link speed of 1Gbps. when I go into the properties of the nic card and set it to 1Gbps, it doesn't connect and says the network cable is disconnected. If I choose auto-negotiation, it will only connect at 100Mbps. I have other devices that can connect to the router at 1Gbps just fine. I have tried the latest nic drivers from Asus's site, I tried installing windows 7 64bit from scratch, I reset the router, upgraded the firmware. all my cables are cat6 or better and I even tried removing all other devices from my router. I just can't get it to connect at 1Gbps. Can anyone think of why this is happening?
