Wi-Fi networks that use Captive portals (like a Sign In page) can be a real headache. You connect to it, and then try to figure out why nothing is loading, and finally Android shows the ‘Sign in to network’ popup. Starting with Android O, the Settings app makes it more obvious that you are connected to a public Wi-Fi network.

While the ‘Sign in to network’ notification hasn’t changed at all with Android O, the Wi-Fi section of the Settings now has a large button to login when viewing a Captive portal network.
