ISP : Verizon Fios

My iphone refuses to connect to the Deco wifi. It will say "Incorrect Password" even though its the correct password. Even if i 'share' the wifi using another phone thats currently connected and it autofills the password it will say "incorrect password". BUT... eventually it will reconnect on its own... eventually... could be hours later.

And even my GUEST WIFI network I set up with NO password on it.. it can't connect and will say "Incorrect Password"!

Ive reset Network Settings on this phone to see if that helped. It didn't.
