Airport drops out after warmup
I was losing airport signal - as if signal strength dropped to zero. It took several weeks for me to track down the correlation. It has to do with temperature.
If I put the Mac to sleep for a while it works again - if I put the Mac on a bedspread with poor airflow the signal drops out sooner. I can move the Mac *much* closer to the AP and it works OK.
Its *probably* the airport card, but it *could* be the antenna connector. The card is cheap enough so I'll change it - but that won't prove that the card was bad - perhaps just re-plugging in the antenna would work.
Anyone else seen that behavior?
Is this a good question?
