I'm using Ubuntu 12.04 in a Samsung 305u notebook and sometimes the icon of the wifi or network disappears from the systray and I have to enter to system settings to enter or disconnect from a network.

Is there some way to fix it?

It must be nm-applet quitting. Check the system log for clues. – mikewhatever Oct 4 '12 at 16:19
How can I acces the system log? I'm kind of new in this. – Pablo Viollier Oct 4 '12 at 19:02
Search for log (Log Viewer) in the dash. It should open showing the System Log, and I'd suggest copying it and pasting to (and the link here). To copy, press ctrl-a to select all, then ctrl-c to copy to the clipboard. – mikewhatever Oct 4 '12 at 19:39
This is the log from the last time the icon disappeared, I hope it helps--> The link from pastebin – Pablo Viollier Oct 7 '12 at 15:17
Well, there are obviously problems with connecting to that network, there is nothing related to nm-applet though. As a temporary solution, you can just restart nm-applet by pressing alt-f2, and typing nm-applet. – mikewhatever Oct 7 '12 at 15:54
