Wifi keeps disconnecting.

It just keeps disconnecting . Utterly fed up with it . It's not the router or anything like thay , tried turning off intelligent wifi , tried factory rest , tried updating . Honestly wish I'd never got a samsung phone

This has been an issue on and off for the last year or so. I have an S20FE

Same router since I have the phone which has 5GHz and 2.4 GHz . 

All was fine between the last two system updates and problem now back. 

It loses the 2.4 randomly and no 2.4 wifi networks will show up as available at all . Restarting the phibe is the only thing that seems to work and that is ridulous. It seem obvious it is a software issue. I do not have any issue with any other devices on 2.4

same problem here  on M23, i hosted a 5Ghz mobile hotspot from my laptop the issue appear back then and lasted for almost a week and then suddenly it just disappear.

but now the problem surface again and it's so annoying because the 5Ghz connection always gone out of nowhere whenever i tried using it to download something even if it was just only a Play Store update, when i do nothing it stays connected.
