How to disable captive portal detection on a samsung 4.4.2

[AC Question]

Hi! In my new university there is a free open wifi network but it asks to put my login details every time that i connect to it (it uses a captive portal).

I found an app to automate the login action in background but my phone detects that the wifi needs login details to receive Internet and disconnect from it and gives me a notification that "sign in required for this wifi network". So i need to tap on the notification to connect to this wifi.

Is there a way to disable this behavior??
I have root and xposed. The phone is a Samsung s3 neo with stock rom 4.4.2

The "behavior" isn't on the phone, it's on the network - and I wouldn't advise hacking the network. (That's how to instantly leave school.) You could install Tasker and write something to automate what gets pressed when.
