Hey All, Recently I have been experiencing issues with the mifi on the iPhone for. What it's doing is when the phone sleeps for a while it turns the wifi signal off but the wifi is still "on" in general settings. I have it connected to 2 ipads and it's the same issue. Before the last update it used to be connected all the time. The personal hotspot connection would always be lit up on top of the phone. Now it kind of turns itself off when it's not being used but still remains "on" in the general settings. Any suggestions?
