My Nexus 4 does wifi fine for a while, and then it won't connect.
The strange symptom that marks it out from other reports around here is that trying to complete the password does not help. It complains about wrong password. (It isn't.) No amount of turning the wifi on and off will restore connectivity.
A puzzling aspect is that it throws up the same "wrong password" message for open sites (BT Fon) that do not need a password.
The way to get the wifi back is to restart the phone. Then it connects fine.
My theory is that I have an app that is somehow upscrewing the wifi. But there's nothing new that might explain it.
So, my question is, apart from uninstalling apps in a trial and error exercise, how do I track down what might be causing this behaviour?
