In my network using WPA-PSK TKIP with mac80211 and b43, I see several of these cycles per day: eth1: RX deauthentication from 00:1a:70:46:ba:b1 (reason=7) eth1: deauthenticated eth1: authenticate with AP 00:1a:70:46:ba:b1 eth1: RX authentication from 00:1a:70:46:ba:b1 (alg=0 transaction=2 status=0) eth1: authenticated eth1: associate with AP 00:1a:70:46:ba:b1 eth1: RX ReassocResp from 00:1a:70:46:ba:b1 (capab=0x431 status=0 aid=1) eth1: associated eth1: switched to short barker preamble (BSSID=00:1a:70:46:ba:b1) In searching through the various 802.11-related header files, the only reason code of 7 that I could find is WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA Is this the correct code? If so, any ideas on why this deauthentication is happening? As can be seen, it isn't fatal and the system always recovers.
