My samsung galaxy S 10 plus wifi connection keeps disconnecting whenever i tried to download anything. Other phones connected to the same wifi do not face any problem and can easily download. I have tried resetting my network upto factory resetting my phone. Hiwever Downloading over mobile data is possible.
The thing is that, i can download while im using vpn apps like turbovpn.
i have tried both your suggestions, but still not working. i guess it might be due to my wifi router which have only 2.4 ghz option, syrotech. My previous phone honor v 10 never had any problem, guess they might fixed with an update or i will have to buy a new router/modem. My broadband connection is bharatfibre. anyway thanks a lot.
