Open the Settings app, and turn on Airplane Mode. Here are the usual tricks, which I always recommend you try first if you're having iPhone wifi glitches: However, I notice sometimes that if I just leave my phone alone for some indeterminate period of time (could be an hour or more), it sometimes randomly connects to the Wi-Fi by itself. When I tap into the 'Wi-Fi' row, that's where I see that my Wi-Fi slider is set to off and attempting to slide it to on just doesn't work. However, it's not actually connected to the WiFi network.
