Can't connect to my WIFI at work

[AC Question]

I just got the Note 5. Where I work we have a guest WIFI in which a new password is generated every night at midnight. When i get to work in the am my phone tries to connect and says that it is connected but it isn't. It can't just connect without putting in the current password. I do not get a log in screen in order to login to this wifi. How can I make it work??? I don't see any setting available on the phone enabling me to do this. My last phone would pick up the wifi when I entered the building and then prompt for the user name and pw but the Note 5 is not doing that. PLEASE someone help! thanks
