I've tried using these instructions: Problem with building/compiling a driver for Edimax wireless adapter EW-7822UAC in Kubuntu 13.10 64-bit

But I get this message in the terminal:

modprobe: ERROR: could not insert '8812au': Required key not available

Any suggestions?



I think this is due to Secure Boot option being enabled in your motherboard's BIOS settings. You'll need to disable it to have the driver installed.

I think you might be one of the victims of dual-booting a version of Windows and Ubuntu (like myself). I've not seen any cases where disabling Secure Boot has caused trouble in Windows so go ahead and see if it works. :)
