Ok, I'm pretty sure this is an AirPort card failure, but since its uncommon, I figured I might check here first. I cannot find ANY wifi network with this mid-2011 MBA. Even with the utility scan and diagnostics. Also, it didn't find it in the boot menu or when I had a WiFi hotspot right by it. I even tried a P2P network, but I couldn't connect to it. Here is what I've tried: PRAM Reset SMC Reset Switching the antennas. Reboot (duh) Switching locations anything else? Any help is appreciated.
