Having same issue, noticed usually when battery levels drop below 50% the wifi starts to drop intermittently as soon as I plug it to charger, wifi gets normal. Have other phones iphone on same network no issue observed on them.
Welcome to the Samsung world Adriyanous. I have the same problem since February and keep loosing my hopes that Samsung can solve it.
I reported this problem several times using the Samsung Members app, but all they can do was to blame my Internet connection for this problem. 🙄 Since I use another 8 devices on the same network without any issues I'm pretty sure, that it is not the cause of the problem.
You can try to disable WiFi6 on your router it could help to mitigate this issue. Such replys from the customer service like "You can also call the customer service representative of the mobile network provider in order to alert them about the status of the signal on your coverage area." tells a lot about the competence of this company.
The best You can do is to wait for a software update which solves this issue. (But it will also not happen very soon. I just enrolled myself to the Beta testing to see if there is a solution for this issue in the pipeline, but there is not. Maybe it improved a bit, but the problem is still there.)
