Hi there, I jumped into the wagon of people having issues with apps disconnecting while using WiFi.
In my particular case I play saint seiya kotz and I can notice lots of disconnects while doing pvp. Or some repeatable pve stuff.
It only happens in my home WiFi network. 4g works fine. Got a Technicolor modem cga2121.
I haven't tried to turn off the 5ghz to see if that's the problem since many folks seem to have this pinned down, but will try later tonight and report back
