5Ghz wifi freaking out

[NotAgain]

So, I don't know how to better explain it
for some odd reason my 5Ghz network connection sometimes go in stupid mode and can't get authenticated​, at which point it keeps trying to connect to wifi constantly. only fix I found is restart of phone or flight mode, but turning wifi on/off, forgetting network doesn't help unless it is coop with a restart of phone 9r flight mode.
It happens at random and it started couple days ago, actually happened when I was typing this.
Any suggestions,fixes or if it is at least know bug?

powercycle your router and forget the network and rejoin

done that, still happening may be a glitch in software somewhere

Hi @NotAgain, assuming that this is a glitch in the software, can you please submit a device error log when the symptoms occur again? From the Samsung Members application, tap the “Feedback” icon. Tap the Pen icon and then submit an “Error report”. This will help us troubleshoot the error. Thanks!
