Windows 7: nforce ethernet issues

Hello

I am having some annoyances with my built in 10/100/1000 ethernet on my nfore 750i MB.
Problem is that the card runs in 100mbit only to my gigabit switch, 1000mbit is not eaven avalible for forcing it in properties.
If i downgrade to old 15.25 nforce drivers, it connects with gigabit as it should, but the problems with those drivers is that.. they were crap, they disconnect alot.
I also tried to unintall and let windows install drivers for it, also works in gigabit, but same stability issues.



The disconnecting issue seems all gone with 15.51, but the drivers seem to think that the card is 10/100 only..
MCP51 LAN controller.
Win 7 x64.

Thanks for any help!

Nvidia web site support has a forum with something that might help.

Yeah, i tried there also, but lots of people with the same issue..
I thought maybe someone here managed to find a fix.
