Mikrotik 751U-2HnD, RouterBoard 3.33, RouterOS , Default factory config with custom Wi-Fi SSID/Credentials config.
Every 1-10 minutes Wifi disconnects or freezes. It’s illustrated on the next GIFs. Here I have 3 terminal windows: right upper - ping from my PC to other local device connected over ethernet, green window - ping to the mikrotik, left one - ping to the mikrotik from other Wi-Fi device connected over USB to my PC.
I tried to set Wifi Security Profile Group Key Update to 1 hour, leave only WPA2 PSK, aes ccm. No result.
I have another router tested with OpenWRT with no Wi-Fi troubles.
Overall Tx CCQ ~ 95-97%
