“AirPort Card”. Select that line.

to step. 5
No: It looks like your iMac recognizes that it has an AirPort Card installed. Go on to
step 6.
5. Remove the back cover and reseat the AirPort Extreme card. Check System Profiler
again to see if the computer sees the AirPort card. Does it recognize the card now?

AirPort antenna is not plugged in all the way, you may have very short AirPort range.

antenna connector firmly, to make sure it's fully connected to the iMac. You should be
