Just did some testing with up-to-date 16.04 LTS: 1. Initial state: Wi-Fi enabled, but not connected to any network; ethernet is unplugged.
$ nmcli general STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN disconnected none enabled enabled enabled enabled 2. Connect to a SSID that has captive portal: $ nmcli general STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN connected full enabled enabled enabled enabled This means network-manager has put the state to connected and emits a signal of full connectivity, which makes other applications "think" the device is online with full access to the Internet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/997200 Title: Test for captive portal before putting applications in online mode Status in NetworkManager: Confirmed Status in network-manager package in Ubuntu: Triaged Status in update-manager package in Ubuntu: Confirmed Status in network-manager source package in Precise: Won't Fix Status in update-manager source package in Precise: Won't Fix Status in network-manager source package in Quantal: Won't Fix Status in update-manager source package in Quantal: Won't Fix Status in network-manager source package in Raring: Won't Fix Status in update-manager source package in Raring: Won't Fix Bug description: When in a hotel there is a often a T&Cs page that is delivered when connecting to the network.
