Nope that didn't change a thing:

wlan0: TXEXC - status=0x0004 ([Discon]) tx_control=000c
   retry_count=0 tx_rate=0 fc=0x0108 (Data::0 ToDS)
   A1=44:44:44:44:44:44 A2=00:06:25:16:c3:73 A3=ff:ff:ff:ff:ff:ff A4=00:00:00:
00:00:00
wlan0: Trying to join BSSID XX:XX:XX:XX:XX:XX
wlan0: LinkStatus=6 (Association failed)
wlan0: LinkStatus: BSSID=44:44:44:44:44:44
