My wifi autoconnects even though i have turned off everything possible in the settings I have a Samsung S6 running Android 6.0.1. There is a guest WiFi at work I signed into one time, and now can't get rid of:


I have tried to "forget" it.
I have turned off smart network switch.
I have turned off all wifi advanced options including "Passpoint" and "network notification" and have tried to turn WiFi off completely


I have done everything possible and it still autoconnects, even if I turn WiFi off within seconds it still tries to connect and drains my battery. When I get home it doesn't auto connect to my house WiFi but sometimes when I'm not even at work it will still try and connect to this guest wifi.

Is this a defect or am I missing something? Is there anything else I can try to get rid of it?
Do you have any app that auto connects wifi, like tasker or Samsung's new application called 'Good Lock'? Because Good Lock creates routines and by default if it gets in some predefined location than it starts wifi and some other services. 
(sorry, I don't know if this can be termed as answer or not. But my reputation is low so I cannot comment and I just thought Good lock can be creating confusion)
