I just got the UD7 board. and at first it worked fine.
got windows installed and then on reboot, had a problem.
network refused to connect.

I flashed the bios from F5 to F7 but that didn't help either.

someone else had a similar problem on the Overclockers.com board.

and their suggestion to fix it was to reset the CMOS and then load bios defaults.

how ever i tried this and it didn't help
quoted from thread above since i have Identical problem.
What it does... with a cable plugged in, I found that the NIC (both of them) is showing in quick succession... "enabled" then "network cable unplugged" and keeps repeating that one after the other.

I have tried different cables / connecting straight to the router rather than the switch / updating the BIOS from F3 to F4 / every time it is the same.

I went into the BIOS and used the smart-lan (I think it's called) feature, and it is showing 187m on all four fields if that is helpful.
anybody experice this before as well and is there a solution besides RMAing the board?
