I have ptp link discAC, 802.11, bridge -- station bridge and there is a loss of connection exactly every hour and the message is in the log:

9:17:48 wireless,debug wlan1: start background scan
19:17:58 wireless,debug wlan1: background scan complete, must select network
19:17:58 wireless,debug wlan1: no network that satisfies connect-list, by default choose with strongest signal
19:17:58 wireless,debug wlan1: failed to select network
17:58 wireless,debug wlan1: did not find better AP

How can I turn it off this function?
