Just got my clamshell today. Its running 9.2.1 and it has an airport card installed. However, I keep getting error code 3278. It appears when I open the airport app and when I go to where there should be networks, and all I see is 3278. I've tried swapping AIrport cards, I tried reseating it, I tried a fresh install... Idk whats wrong with it, but its annoying me to no end. Any ideas?
