@lhari84 Unfortunately that didn't work. 
I haven't yet tried the NUC with gamecube/WII, but I actually bought it because it seemed it would play PS2 games, unfortunately it's not quite up to the task - however I would think Gamecube at least would be very smooth.
I think i have a RC3 bug on my Intel bean canyon i7 NUC running the PC 64bit build. Doesn't matter what I do with the wifi settings, I can't get it to connect - there are no errors on screen, the machine will simply just stays at "NOT CONNECTED". Correct SSID and WPA2 key are set, and I've tried rebooting a couple times. Running a clean RC3 image, bone stock settings.
Maybe a bug?
