I go through all the beacon frames again and found that Ruckus AP update WMM IE:wmm_parameter_set_update_counter. But it's strange that other elements of wmm settings remain unchanged, RUCKUS just update the update_counter for none of wmm settings updated actually .......... thanks 2009/7/8 Holger Schurig : > On Tuesday 07 July 2009 18:28:47 fengzeheng wrote: >> hi, dan and all >> ? ? ?My wireless card sd8686 reports that wmm_config_change >> about every 2 seconds though wmm's setting in AP's beacons >> don't change. seems that driver receive >> MACREG_INT_CODE_WMM_STATUS_CHANGE event from firmware every 2 >> seconds.
