FWIW, here's Android's code to detect it: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.1_r1/android/net/wifi/WifiWatchdogStateMachine.java#WifiWatchdogStateMachine.isWalledGardenConnection%28%29
Seems they connect to something returning status 204 and expecting that code or else will open the popup. -- 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/1571522 Title: Detect captive WiFi hotspots Status in Canonical System Image: Confirmed Status in indicator-network package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: New Bug description: Right now it is very annoying that when you connect to a captive wifi portal, the device does not detect that. All other devices open the log in page automatically, except ubuntu devices. One needs to manually open the browser, type a url and get redirected before being able to log in and start e.g. telegram messaging over the wifi connection. My proposed solution to solve this: When a WiFi connection is established, indicator-network should do a http GET call to ubuntu.com. If the reply turns out to be a redirect, it should open the browser with the redirect url.
