I haven't replaced any hardware at all. I just checked the hardware info using the iATKOS v7 dvd, and it is an Atheros AR928X wireless card (168c:002a). I followed your installation method and reinstalled osx86 using iATKOS v7. I tried adding my device id to the AirPortAtheros.kext and repaired permissions but that didn't work. Are the any other kexts that might be compatible with this particular card?
