I'm having a problem that I thought was a AirPort network problem and I'm beginning to wonder if it might be a problem with my MacBook's AirPort hardware or connection. I'm going to post this in both the wireless > AP forum as well as the macbook one in case I'm misdiagnosing it.
It started when I was trying to extend my wireless network from an AP Extreme n with an AP Express g. I found a lot of advice on the wireless forum and finally bit the bullet and bought an AP Express n to extend it. After some problems getting those in sync it seemed to accomplish what I was trying to do.
But as I've been making these changes I noticed that my MacBook Core Duo seems to not pick up the signal like it used to. If I'm right on top of the AP base station I get a full signal, but as I move 30+ feet away it diminishes until it drops out completely. And this is in areas where I used to get a strong signal. I've got my AP base station in the same location and I can use my iPad in areas where the MacBook doesn't find a signal.
Is there a way to test the AP receiving hardware in the MacBook? It is about 6 years old, so it could just be giving out. Here's what showing under the About This Mac - Airport menu. I'm about 30 feet from the base station now.
