I am aware that a thread has existed for months, if not years regarding hostapd disassociations, but my shock at how this issue continues unresolved prompts me to push this issue to the top of the pile once again.

While the Atheros drivers have been the leading suspect to date (among others in the ongoing witch hunt), may this have something to do with RADIUS authentication? It seems the disassociation always immediately follows the start of an associated RADIUS accounting session. Just a thought.

Also, the error log specifically states that the deauthentication is due to inactivity. How does the DEAUTH/REMOVE timer function? Might there simply be a bug in how associations are being timestamped? Just another thought.
