Hostapd de-auth connected clients

[ravin goyal]

Hi again

I have installed debian jessie lite on my banana pi m2+ board and
running hostapd 1:2.3-1+deb8u3 and wireless driver is bcmdhd for
wlan0.
initially hostapd runs fine but after some time it disconnects all
connected clients one by one.

when I tried to reconnect again, it gives following error while I was
running hostapd as: hostapd -d /etc/hostapd/hostapd.conf

nl80211: Drv Event 20 (NL80211_CMD_DEL_STATION) received for wlan0

While at the same time in syslog this is what I found :

Following is the message when a now client tries to connect:
