My phone keeps saying that i have internet signal and my router is working fine. I have Wifi working on my ps3 and ps4 and Ipad, but our Lg G4's just recently started saying that the Wifi is unavailable and then says it is disconnected. When you click on the Wifi on the phone it says good signal and says its on though. It also says disconnected due to poor internet connection, but its not my internet. Why is this happening now?
