Annoying wifi screen pops up whenever I attempt to use my phone outside (away from my home wifi)

[AC Question]

So I'm using a Galaxy Note 5 and recently I've noticed this same screen pops up (I suppose wanting me to connect to a close by Wi-Fi network) every time I attempt to use the phone away from home? It's driving me nuts as it causes additional (unnecessary?) button presses to clear. How do I attach a screen shot for more detail?

There should be an option to turn off notifications in the Advanced wifi settings.
