Apple AirPort Extreme Model A1143 Wi-Fi Antenna Replacement

  • Step 1 Back Pad

    • The back pad is held in with glue so use caution when removing to prevent tearing. Low heat may be used to help remove the pad.

    • Slowly peel off the rubber pad on the bottom of the device. Start from one corner and peel with your fingers. Use heat if necessary until pad is completely removed.

    This is where you would use the opening tool. It's the perfect tool to lift the rubber base around the metal lip and then pull with your fingers.

  • Step 2 Back Cover

    • After removing the rubber pad, unscrew the five 5mm phillips #00 screws in the holes of the back cover.

  • Step 3

    • Lift up the back case from the perforated edge to remove it.

  • Step 4 Remove from Case

    • Remove logic board and metal casing from outer case by prying from one side using a spudger.

    I have found it easier to lift from the side with the Ethernet ports. When putting back together watch that the three WI-FI antennas don't get snagged against the case as your putting back.

  • Step 5 Detach Logic Board From Case

    • Unhook the wires connecting the logic board to the metal casing by grabbing and pulling up on each connection with tweezers.

  • Step 6 Pull Back Tabs

    • Carefully push back the three metal tabs with your fingers on the sides of metal case.

  • Step 7 Remove Metal case

    • Carefully pull the metal case away from the logic board.

  • Step 8 Wi-Fi Antenna

    • Unscrew the 5mm #00 screws from each of the three antennas located on the sides of the metal casing.

    • Pull away antennas from metal case.

  • Step 9

    • Pull up the less visible silver tape that holds the antenna cords in place at the ends of the device using your fingers.

    • Remove clear yellow tape that holds the cords to the outer casing in the same manner.
