I got 12.04 LTS but it happened in 11.10 too.
The thing is that the network icon disappears from tray without any warning. I've noticed it happens when the connection is weak and unstable, but I know it is just a graphical problem because it still works when it manages to reconnect automatically. When it doesn't, I can't find another way to put it back other than killing the X server or simply rebooting the OS.
But come on, this is Linux, obviously there is a way to solve this. So
- How I make it not to disappear ever again?
- At least, what can I do to make it reappear (I suppose with a command in terminal)?
