So I lose my airport tonight, after bringing the computer with me home from work on the motorcycle (nothing new there, do it all the time). I reboot - nothing, remove and re-insert the card, nothing, do a reset of NVRAM, nothing, reset open firmware - nothing, reset the PMU - IT WORKS! I put the computer to sleep, wake it up again later and airport is gone again. I reset the PMU, etc etc again, NOTHING. Swapped out the card and repeated, still nothing. Any ideas?
