Help! My iPhone 5c is not staying connected to wifi. This happens both when I am at home and at work. I will pick my phone up after not using it for a while and it will be at a black screen (power saving mode). Once I press the main button it will come up to my lock screen and I will see in the top left corner that it is on LTE and not wifi even though I am either at home or work where it should always be connected to wifi. Once I enter my passcode and get back in it will come up and sometime then connect back to wifi or I have to go slide up the bottom menu and disable/enable wifi then it works, and occasionally I even have to go into Settings, Wifi and then all of a sudden the iPhone will reconnect on it's own to wifi. This is troubling because I am almost going over my data limit this month and when I look at a report of my data usage my phone is using data in the middle of the night when I am sleeping and should be connected to wifi! Verizon if you are watching these forums help me out here and/or I will be calling support soon too. Thanks for any ideas or help!
