I get this too. I would love to kill this splash screen. It opens up whenever I'm out of range of a "saved" WiFi signal. None of the buttons load anything, and I've never used this screen to save a WiFi connection. You would expect Smart WiFi to just use 3G/4G when a saved network is out of range, or at the very least display some non-intrusive message that you're no longer connected to a saved network. Instead I get this popping up over and over again covering up SMS and other apps. Super annoying.
