That local choice (reason=3) is NetworkManager terminating the association attempt because it already took 25 seconds, which is way too long for a simple association. The cause is long before that. NM tells the supplicant to start associating here: Mar 19 17:05:07 stt300 NetworkManager[30971]: <info> Config: set interface ap_scan to 1 and finally kills the attempt here: Mar 19 17:05:32 stt300 NetworkManager[30971]: <warn> Activation (wlan0/wireless): association took too long. So the supplicant gets a total of 25 seconds to associate to the AP, which, if you're not associated within that time, you're definitely not going to get associated if you're given more time. But between 17:05:07 and 17:05:32, NM is just waiting for the association to succeed. It really does look like the supplicant or driver tries to associate but then fails, eg: Mar 19 17:05:08 stt300 kernel: [26014.833011] wlan0: send auth to 00:1a:2b:97:7a:97 (try 1/3) Mar 19 17:05:13 stt300 kernel: [26019.834259] wlan0: deauthenticating from 00:1a:2b:97:7a:97 by local choice (reason=3) There's a whole lot of authentication/association failures in that log, which do appear to indicate that the STA can see the AP, but the AP can't hear the STA. Then we also have stuff like: Mar 19 17:05:24 stt300 wpa_supplicant[2855]: wlan0: SME: Authentication request to the driver failed where it would be nice to know why the request failed.
