So yesterday and all the days before my phone worked fine. But now today the Wi-Fi won't connect. I know the Wi-Fi is fine because I'm on my computer on this site. My phone will connect for about 5 seconds then boot me off again. I've tried restarting the phone, turning off mobile data, shutting the phone off and back on, disconnecting and then connecting again, putting back in my password for the Wi-Fi and none of it will work. I didn't notice this problem until I used ALL my data and now I can't connect to anything. What do I do to fix it?
