Hi guys In the end I replaced the module by a Broadcom one a few weeks ago. The laptop is running as clean as can be. It never freezes, I suspend/resume it all the time and I disable/enable network at will. I rebooted maybe 2-3 times over the past weeks, mainly because of installed updates.
I could not get a meaningful error code out of the ath9k driver although I tried all procedures. I am not a developer, but maybe a debug module printing out some essential status information could help here.
