[Android 5.1 Feature Spotlight] Android Now Recognizes Wi-Fi Connections With No Internet Access And Won't Connect To Them

Note the text below the COPA network.

Android 5.1 will solve that problem. (The problem of connecting to a dud network, not the one about the bar's crappy router.) Once a device running Android 5.1 connects to a router that has no Internet access, it will remember it, and won't automatically connect to it again. This will be a boon when travelling to restaurants, hotels, and the homes of elderly relatives everywhere.

The first release of Lollipop included a few tools to help users better identify and avoid dud Wi-Fi, but now it looks like Google is simply trying to avoid useless connections altogether. Makes sense to me. Other 5.1 additions in the same vein include disabling Wi-Fi or mobile data from the lockscreen and switching networks from the Quick Settings menu.
