Having issues with wireless connectivity? The problem could lie inside the AirPort Board.
This guide will show you how to replace the AirPort card installed in the display frame of the Early 2009 and Mid 2009 MacBook Pro 17" Unibody. This guide does not apply to the Mid 2010 and Late 2011 MacBook Pro 17" Unibody. The AirPort card in the later models is mounted beside the optical drive.
