And according to firmware spec v5.1 this event generated when firmware monitors a change in wmm state. This is a result of an ap change in the wmm parameter ie or a change in the operational state of one of the AC queues. However , I can't find any change of AP's wme settings in beacon from the sniffer packets. So why does firmware send this event? thanks for your any comments. -- Best Regards Fzh
