    Hi folks I'm new here,

    I was trying to remove the superdrive from my mackbook 2012 and replace it with an extra hard drive bay.

    I accidentally snipped one of the antennas. It's connector is labled J3 on the airport board. Does anyone know what this particular antenna is used for? I'm wondering if it would easier to buy a USB replacement dongle, or replace the antenna.

    The Wifi works fine. My hunch is that it's bluetooth related.

    Thanks,
    Steve

    I'd guess the J3 connector is Bluetooth.
    Why don't you just check to see if your Bluetooth is working?

    I tried that with mixed results. My phone sees the Macbook, but the macbook can't see anything. I'm really just trying to confirm without any doubt. This is my first Mac so I'm not quite used to how it behaves with certain functions, like with bluetooth.

    Next step

    I took an antenna from another laptop (didn't fit perfectly), and it seems that J3 is responsible for bluetooth reception.

    Now the question is this,

    This particular antenna doesn't seem to be part of the main group of antennas included in this replacement part, I can only see three connectors.
