Hi
I am having similar problems with my airport card on a first-gen MacBook. In my system.log I get errors such as these:
Apr 2 10:22:19 Lena airportd[940]: Could not find any preferred networks; trying broadcast requests..
Apr 2 10:22:22 Lena airportd[940]: Broadcast requests failed..

Apr 2 10:39:35 Lena SystemUIServer[966]: Error: airportd MIG failed = -6 ((null)) (port = 37895)
I am on 10.5.2.
As described, it works perfectly fine after a complete reboot for a while and then completely drops out. The thing is: it worked perfectly fine for me on Leopard for months now, only after I installed this time machine and airport update from Apple things started to go really wrong! Any help out there?
