I have been using my phone on home wifi network for 6 months now, and this has never happened before. Every device in my home can connect just fine with any hitches. Just today, mine phone decided to not connect properly anymore. I will connect to network, and go on browser but it just spins in a circle forever. I have restarted my phone, restarted router, wifi on/off, forget network and reconnect. Nothing has worked. My phone is samsung galaxy core, 4.4.2 android. Any help is appreciated.
