It of course depends on which network indicator you mean (I'm guessing nm-applet unless you installed indicator-network separately), but regardless, whether a network is secured is shown by a small padlock at the bottom left corner of icons (though it may be different in other themes, and show elsewhere over the icon).
Marking as invalid: provided your theme provides the right *-secure icons, there should be a padlock on the image or some other indication that a network is secured, unless it's an ad-hoc network in which case it will just show as that. ** Changed in: network-manager-applet (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778034 Title: Indicator menu does not show whether wireless APs need authentication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/778034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
