It disables after a few minutes and switches to my data. I've tried turning my phone off and on again, switching wifi networks, but nothing has helped.
Ok so my best guess would have do,ube that in your settings it is set to automatically disconnect from weak or slow Wi-Fi networks what you need to do is go into your settings (sometimes you even have to go,into advanced wifi) and turn this feature off,i hope this was to,help to you
