Upon reading your posts I decided to experiment, with:

ping -s 65507 192.168.22.1

that command will actually crash my AP! (a d-link di-624 Rev b)

I get these messages in my log, Im guessing they are saying my AP
dissapeared without saying goodbye, but I haven't had time to investigate...

This most likely doesnt have anything to do with the prism54 driver though, 
just thought it might be interesting...
