Started few days ago, my iPhone 4s keeps disconnecting from wifi. It's on iOS 8.1.2 . Everytime I open an application that uses network, wifi gets disconnected. Such as App Store, Skype, Clash of Clans and all other app that uses network. After the disconnection, either it will reconnect to my wifi or it won't connect until the next reboot. Sometimes, when I switch off the wifi toggle, my phone freezes and needs to force reboot in order for my phone to unfreeze. I think the reason that this happened is because my phone fell and hit the floor alot of times and might have damaged the phone inside or there is a software problem. Any solutions or real reason to this?
