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

Scan timeout - try to get results

^ timeout here

nl80211: Scan trigger failed: ret=-16 (Device or resource busy)

^ new trigger fails


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