wirless, not able to ping devices in other wifi band

[Pergola Fabio]

hi, running 32799 on my rt-ac86u

after a while , a day or 2 or something, i am not able to pin my devices anymore in the other wifi band
so if i am in 5 ghz, i can ping the wifi devices in 2.4 and vica versa

devices are all still online though

if i reboot the router, its working again for a day or 2

alreay tried a factory reset

any1 else experiencing this also ?

I experience this as well on my AC 3100, stock firmware ( and Merlin's ). Only way I've been able to avoid it is turning off Airtime Fairness and possibly turning off MIMO for both 2.5 and 5GHZ.

Ok, I think you solved my issue, seems stable now, disabled those 2 settings
