I have a PC on which I've installed Ubuntu 12.04 in dual-boot with Windows 8.1. My problem is when I start the PC on Ubuntu, wifi doesn't work, but if I put my computer in standby then I get it out from standby, wifi works... My PC is the Asus X552C and my wifi card is the Atheros 9485.

Thank you per advance!
