I find it rather unstable. A typical cycle between authentication and disassociating is as follows: [ 1066.227729] wlan8: authenticate with 00:1a:70:46:ba:b1 [ 1066.238397] wlan8: send auth to 00:1a:70:46:ba:b1 (try 1/3) [ 1066.440128] wlan8: send auth to 00:1a:70:46:ba:b1 (try 2/3) [ 1066.443739] wlan8: authenticated [ 1066.448139] wlan8: associate with 00:1a:70:46:ba:b1 (try 1/3) [ 1066.456657] wlan8: RX AssocResp from 00:1a:70:46:ba:b1 (capab=0x411 status=0 aid=1) [ 1066.456673] wlan8: associated [ 1066.458051] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 1066.458067] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: associated [ 1066.458087] ieee80211 phy0: changing basic rates failed: -22 [ 1066.458101] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 1 (implement) [ 1076.464670] wlan8: disassociating from 00:1a:70:46:ba:b1 by local choice (reason=3) [ 1076.465981] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 1076.466051] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: disassociated [ 1076.466074] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled false, count 1 (implement) [ 1076.490224] cfg80211: Calling CRDA to update world regulatory domain [ 1076.507338] wlan8: deauthenticating from 00:1a:70:46:ba:b1 by local choice (reason=3) The period of time that the interface is up ranges from 10 - 200 seconds. The connection is WPA-TKIP and the kernel is master-2012-02-15-510-g20b79b4 from wireless-testing with local patches applied to other drivers. Both brcmsmac and bcma are untouched. Thanks, Larry
