I have a 2011 macbook air, that upon wakeup had a message where the wireless bars should be that says "no hardware installed". I have tried a couple tricks I got in support forums but nothing worked. this included tring to downgrade the family.kext file but couldnt get the drag and drop kext utility. turning the bluetooth on and off and restarting has got it to work for a couple minutes but then fails. I keep trying the mac hardware test of turning on and holding d but that takes me to an internet test that wont connect. does anyone have an idea of what I should do???
