I've had the iPhone 6 Plus for several months now without any problems. Since updating to the latest IOS update, however, my ability to connect and use wifi has been limited. The phone will show connected to my wifi network. The problem is that it isn't really connected. I can't do anything on wifi. It shows connected, but it's really not. I can't backup, search Safari, download apps, or anything else that uses wifi.
I have tried "resetting your network" and a few other things but nothing has worked. Please help!
