I've got an annoying AirPort-related problem with an early 15" unibody MacBook Pro. It happens in two ways: either AirPort will turn itself off and not turn back on until I restart or the computer completely freezes and I have to restart. Besides happening only when I'm using wireless, it's completely random. It doesn't matter what I'm doing, if I'm on battery or plugged in, or how long it's been since the last time it happened. I've looked in Console and haven't found anything relevant. Does anyone have any idea what's going on?
