    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.

    Does Bluetooth work? The same card (but a different chip) handles BT and Wifi, so if BT works I would suspect the antenna or antenna cable. If neither work, then possibly the card itself. It's easily replaceable and not expensive. The antenna cable goes from the Wifi card through the screen hinge and into the display, and the cable could have been damaged. I am not aware of any repair procedure to fix this, other than replace the display assembly.

    What does your WiFi menubar icon say when you click on it? If it says "No Hardware Installed" then you've got a hardware issue somewhere. I just went through this on my Mid-2012 MBP. In my case it was caused by damage to the cable that connects the Airport card to the motherboard. A replacement cable cost me $10 off of eBay.
