I will try to get you the detailed logs. I am not at home right now, but hopefully my travel access points lets me reproduce it.

Which AP is it? It is an AVM Fritz!Box 7270 with their latest firmware.

Will try to get you all the details needed. Funny part here is that the problems stated with my 5350 card. The old 4965 in my X61 used to work perfectly fine with the exact same access point.
