Hello Master Mikrotik,
We use MikroTik 52Hpn r2.
We have a wireless connection problem that is too often disconnect.
My logs related to disconnect :

Jul/10/2018 12:29:04 wireless,info API: 12:81:1E:1F:CD:A2@wlan1: disconnected, group key exchange timeout
We have one AP MT 52Hpn and 17 Client Android TV box/Embedded PC in one hall room with a little obstacle and many others AP Cisco in one area.
In one day we have too often logs like above.
I attach some screenshot information.
Please give us clue how to settings the MikroTik to make solution about this problem.
Thanks in advance!
