  • 820-2879-B No wifi

    I have runned ASD and there were no problems with that. Have tried other lcd and still no wifi. Installed new OS X and still nothing.

    What should i check?

    Check if L3404 is fried. If it is then the APX card was plugged in wrong way around or the cable is shorted. Could also be a fucked up connector.

      You tested the connector on the board....
      Got 5V on L3404? Check continuity from pin 1,2,4,5,7,8,10,11,12 to the connector on the APX card.
