Network Manager applet
I'd like to find out what the icons mean within the Network Manager applet. I'd include a screenshot with this question, but at the moment, I have no wireless networks nearby.
- One icon is a disc shape, which I know means a password-locked wireless network.
- When there is no icon at all, the wireless network is not protected.
- A third icon is two monitors stacked together. I have no idea what that means.
There seems to be no indication of what the icons mean in any other the Gnome NM applet documentation that I've looked at.
