[First post!] I am having a small driver issue while trying to install 64-bit Windows 7 on my iMac 27. Essentially, all drivers will install excluding my Atheros AR9280 wireless card. The error message (abridged) reads "No 64 bit driver for this card." That said, the driver does exist. I've tried using ethernet to download the 64 driver online, and bumping it over on a flash (from my PC). In my setup, it isn't exactly convenient to stay plugged into an ethernet jack. Any suggestions are much appreciated <3.
