iPhone 4s doesnt detect Wi-Fi
My iPhone 4s with iOS 8.3 doesnt detect my home Wi-Fi or to be specific it joins for a while then it disconnects after a while.
I've tried resetting my network settings, turn on and off the device and turning off an on the Wi-Fi router.
It was working fine until this morning. I put it on charge when the battery was getting low and after charge completion it ended up like this
Help!!!
