Hm, no atheros cards installed here, it's a desktop system that's
experiencing (used to experience? ;-) these problems.

Good to hear though that you seem to have found a way around the problem.

I can't reproduce that, what means I don't know a aplication or usage of the system making it freeze. sometimes I have uptimes of a day, without freeze and sometimes it freezes right after booting the system.

In the system log I can't find any unusual entries. But I foun that the system log is still runing, so shuting down the wifi with the notebooks hardware switch for example is logged. Also the Wifi network connection to my router is not interrupted.
