Push the AirPort/Bluetooth card slightly downwards, 1-2 mm at most.

With a firm grip on the edges of the AirPort/Bluetooth card, pull it straight out of its socket on the underside of the logic board.

Do not use excessive force to pull the end of the AirPort/Bluetooth card away from its socket on the logic board. Doing so may cause severe damage.

Try not to touch the antenna connector sockets with your fingers, as the oils can corrode the metal and prevent good contact.
