Alright, so I have searched high and low for a fix for this, but nothing has proved mildly useful. About two days ago, my phone's wi-fi stopped working completely. I initially assumed it was the wi-fi at my own house, but it is completely non-operational regardless of where I may go, including my friend's house, and the college I attend. The phone is connected to the respective network at all of these locations, but it refuses to work. I cannot use the Internet browser, my internet radio app, wi-fi calling, or any other features one might require internet usage for. And no, I do not have or need a data plan.
