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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571522 Title: Detect captive WiFi hotspots To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1571522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
