AirPort won't turn on unless restarted, then causes computer to freeze
Hi there, I've been experiencing this problem for about a week now and it's unlike anything I've ever encountered before. I'm on a 2008 MacBook Pro 17 which has never caused me any major problems up until now. Basically, about a week ago my airport would randomly turn off and would not let me turn it back on. I tried various fixes for that posted from around the internet, but the only thing that would help would be a restart. I've been using ethernet for internet in the mean time, and that works completely fine. However, upon restart, the WiFi would either work for 5 minutes and then turn itself off, or if it lasted any longer than about 5 minutes, it would cause the computer to freeze completely without any functionality, as if the screen had been "paused", no rainbow wheel, no anything. Interestingly, if the ethernet is plugged in the WiFi stays on AND the computer doesn't freeze. So it must be a problem with the airport. I haven't installed any new software lately, and the only update I did last week was for Java runtime or something like that. I've looked over the internet but haven't found any similar instances to mine, and was wondering if anyone had similar issues and was able to resolve them?
Many thanks!
MacBook Pro, Mac OS X (10.7.2)
