Connect fails with error: The important information is not what you posted here, but still in the dmesg file you provided. In that log we see the following right before the warnings: [ 163.126590] wlan0: direct probe to AP 00:1b:11:f6:0f:28 (try 1) [ 163.130027] wlan0 direct probe responded [ 163.130032] wlan0: authenticate with AP 00:1b:11:f6:0f:28 (try 1) [ 163.131924] wlan0: authenticated [ 163.131952] wlan0: associate with AP 00:1b:11:f6:0f:28 (try 1) [ 163.134325] wlan0: RX ReassocResp from 00:1b:11:f6:0f:28 (capab=0x431 status=0 aid=1) [ 163.134331] wlan0: associated [ 163.155938] wlan0: deauthenticating by local choice (reason=3) It shows that association was successful, but something in userspace requested a disconnect. > > [ 163.208063] ------------[ cut here ]------------ > [ 163.208114] WARNING: at net/mac80211/scan.c:267 > ieee80211_scan_completed+0x299/0x2b0 [mac80211]() I cannot get an exact line match based on the kernel information you provided. I assume it is the first warning in ieee80211_scan_completed(). This is not serious as it indicates that mac80211 received a "scan completed" indication when it was not scanning. > [ 163.232845] ------------[ cut here ]------------ > [ 163.232908] WARNING: at net/wireless/core.c:613 > wdev_cleanup_work+0xbb/0xe0 [cfg80211]() This warning has just been reported in linux-wireless also.
