Introduction
Replace a faulty AirPort card to regain wireless internet connectivity.
Tools
-
-
Stick a heavy-duty suction cup near each of the two top corners of the glass panel.
-
While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle (as indicated by the third picture).
-
-
-
Gently lift the glass panel perpendicular to the face of the LCD, enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.
-
Pull the glass panel away from the lower edge of the iMac and carefully set it aside.
-
-
-
Carefully lay the iMac stand-side down on a flat surface.
-
Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.
-
-
-
Use a pair of tweezers to pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac.
-
-
-
Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.
-
-
-
Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.
-
Pull the display data cable connector away from its socket on the logic board.
-
-
-
Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.
-
-
-
Carefully pull the display toward the top edge of your iMac and lift it out of the outer case.
-
-
-
Use the flat end of a spudger to pry both AirPort antenna cable connectors up off the AirPort card.
-
To reassemble your device, follow these instructions in reverse order.

Finished and succeeded :)
I tried to exchange my broken AirPort card twice already but my iMac still can’t connect (and find) any wireless networks. As i bought the AirPort card which i exchanged today from an dealer, claiming it “new”, i guess i have any other problems. Anybody can help me with it?
in my 2011 21.5” imac i somehow broke one (the very right one) of the thin wires that connect to the airport card mount, actually broke the connector. no sure what to do. any info?
You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.
