I just bought a new mbp and my old 17" MacBook pro 2006 2007 models screen was not really working so I decided to take the screen off and use it as a kitchen computer with an external monitor. The problem is that my airport extreme is in a room right next to the kitchen and the old mbp is not picking up any wifi signals not even the neighbors wifi but, my new mbp can pick up the signals where is the wifi antenna located?
