I have 3 DECO M5 v3 with 1.5.3 FW

I have 40-50 WiFi device connected.

All seems to go well, except for a Xiaomi Redmi 9C phone that disconnect itself  and quickly reconnect about 8-10 times in an hour.

If I take a look at the logs I found that this phone is tested for 11k every 6 seconds all the time 24/7

Furthermore, the phone is quickly disconnected and reconnected from the same AP, which causes the game to interrupt (and the kid to complain)

Can this be fixed somehow?

Thanks!
