Why is it so fucking difficult for mobile OSs (Android/iOS) to revert to mobile data when the WiFi is clearly not working? It’s so annoying when my phone connects to some AP 10 fucking nautical miles away and tries desperately to get a connection to the internet when I have a data plan that works just fine. The solution would be so fucking simple: before the phone switches to WiFi connection it should simply probe the internet. Login required? Ask me if I want to proceed before showing me the fucking login portal. No response at all? Then don’t even bother going any further with it.
