[T-Mobile Galaxy Note 4 Android Development] ChrisJ951:
Was using WPA2 personal. Let me re-enable it and try modifying the file manually. Also I don't believe it's a lollipop issue as I have no issue connecting from a Nexus 6

EDIT: So re-enabling the password and it seems to work now. I had rebooted twice without success so I'm unsure of the exact reasoning why it was failing earlier? If it happens again I'll try to get more information on it. It used to immediately popup saying it failed to connect as soon as I entered the password.

2nd edit:

Here was an adb logcat back from when it was happening
