I seem to have managed to delete my default launcher icons in the top right panel on my laptop running ubuntu, specifically the battery monitor and the wireless network ones. I now can't connect to the internet since I can't find this guy and the administration>network one doesn't seem to do anything. How do I get these default launchers back? The add launcher menu doesn't seem to have them?

Another small random question that I had was how to disable the keyring from coming up everytime I start up asking for permissions for nm-applet, which I assume is the network manager applet.

You can add those icons back by right clicking on the panel where the icons used to be and clicking add applets. It might not be add applets, but definitely adding something. Then just look for the ones you're missing in the menu that comes up.

That first page is applets, then there are options for application launchers and custom launchers. The problem is, none of those applets appear to the be ones that I originally had, I tried a whole bunch of them. Unless I just missed the right ones, I don't think they are in that selection.

For the benefit of others the answer ended up being to re-add the "notification area" applet.
