I understand that Intel have common drivers for the whole series so not surprised the same issue is with the others. As posted so far, if you're going to replace the card select another maker's. I selected a Broadcom and it's rock solid stable. I have lost WiDi and the bluetooth is not low energy Windows 8 compliant but better than what I had with the lame $25 6235 that shipped with my $1,200 Samsung T700.
Good luck
