I have an HP Pavilion P6 desktop with an integrated motherboard, and the network will not come up in live CD nor when installed. I have disabled UEFI. I have tried plugging in a D-Link DW-31 USB wireless dongle, and it is also undetected. I have swapped the hard disc with Windows 8 for a clean one, and the install still fails to find the card. If I do the install on my old Dell Optiplex 280 everything is fine, and I can also get it all working on my Asus netbook with Broadcomm chipset.
