Yes, it would be the wifi extender. And I have nothing plugged into it. When I turn it off, it only stays off for a little while and then it goes back on. Also, I did do all the updates on everything about 2 weeks ago. But I've had several perfect flights since then. I even had a great flight the night prior. So it doesn't seem like that would be the problem. This is my older P2V and it has been extremely faithful (other than user error lol). How hard is it to replace something like this? Is it possible that when I slid the controller into my foam case I pulled something lose?
