I have a 2006 Macbook. My AirPort signal gives out after five minutes of internet service. I don't live anywhere near an Apple store, and no, it's not the wireless stations, it's the computer itself. What do I do? Anyone else have this sort of problem? Why is the AirPort so touchy? The signal is super strong one minute, then two minutes later, it's dead, as though there's no signal at all, even though I know the signal is strong.
