My AirPort signal seems to be very week
1.
Check your antenna. If the AirPort antenna is not plugged in all the way, you may have
very short AirPort range.
2.
Remove the back cover. Reconnect the antenna cable to the AirPort card. Press the
antenna connector firmly, to make sure it's fully connected to the iMac. Replace the
cover and reconnect the power cord.
3.
Try connecting to your wireless access point now. Did your reception improve?
Yes: It looks like the AirPort antenna had not been plugged in all the way. You should
be ready to go wireless now.
No: It continues like your antenna is plugged in properly and your AirPort card is
recognized. However, there are a number of other things that could cause issues with
wireless networking. Refer to Knowledge Base document 106858 for more
networking information.
4.
Replace the AirPort card.
5.
Replace the logic board.
