You seem to have driver issues. After getting disconnected (for some
reason, but this isn't surprising), you get:

wlan0: State: COMPLETED -> DISCONNECTED
...
Scan requested (ret=0) - scan timeout 30 seconds
nl80211: Event message available
nl80211: Scan trigger
Scan timeout - try to get results

^ timeout here

wlan0: Event SCAN_RESULTS (3) received
nl80211: Received scan results (0 BSSes)
wlan0: BSS: Start scan result update 3
wlan0: New scan results available
wlan0: Selecting BSS from priority group 0
wlan0: No suitable network found
wlan0: Setting scan request: 5 sec 0 usec
wlan0: Checking for other virtual interfaces sharing same radio (phy0) in event_scan_results
Scan SSID - hexdump_ascii(len=12):

wlan0: Starting AP scan for wildcard SSID
nl80211: Scan SSID - hexdump_ascii(len=12):

nl80211: Scan SSID - hexdump_ascii(len=0): [NULL]
nl80211: Scan trigger failed: ret=-16 (Device or resource busy)

^ new trigger fails


So whatever driver you're using seems to be broken.
