WiFi ! on Android 5
I wonder if anyone has seen this annoying problem on Android..I have a Sony M2 phone with Android 5.1.1, and I'd normally have it connected to the wifi network at home. This does work most of the time with the WiFi icon happily sitting there with its up and down arrows etc. So how come when I pick it up, it sometimes has lost connection and has an exclamation mark next to the WiFi symbol. Does anyone know what that means? It seems really random.. It goes away all by itself after a time, but is there any way to stop that happening?
