Z77 Extreme 4 LAN port doesn't work at 1000 full

Solution
What about chaning the cabel and make sure, you have all four twisted pairs? That all sounds like a physical connection problem. You can download the diagnostics program from Broadcom to sort that out without even touching the cable.

Wow. You sir are an absolute daemon. In all my years experience with computer networking, I have never ever come across this problem & wouldn't even think about it as being a potential problem. Well done! I just tested this using another cable and it worked fine. So you are spot on. I can't believe it. Thank you very much!

EDIT: I just found the dodgey patch. It was a cable I hadn't punched down properly in my patch pannel. I punched that down properly and now I'm getting a 1 gig auto negotiation. Learned today that GB uses 4 pairs and 100MB uses 2 pairs. I actually didn't know that. Thanks for helping :)
