I am using Ubuntu 10.10 Maverick, and I have this problem where the NetworkManager just quits randomly causing the internet connection to be broken. The only way to get it back is to log-off or restart the computer. This is very annoying as you have to close all the work you are doing and log-off or restart the computer.

The Networkmanager icon in the panel is not visible anymore when it quits as shown in the screenshot here. enter image description here

However the hardware icon for the wireless is still on which shows that this is a software problem.

Has anyone else experienced this problem? Is there a command or something to restart the networkmanager applet when it quits?

The command for nm-applet is nm-applet. You could try that from command line. On a very different note may be you could try some alternative for network manager like wicd.

I too have a lot of issues lately with Network Manager. It all started with bluetooth tethering dying, which led me to download a beta version, but that one had a major memory leak. however, that beta version also had the issue that the normal one did and that yours did. I have not see any fix yet, but here is what i found out through someone else:

from command line type

killall nm-applet

then hit Alt-F2 and type


then hit ok.

The reason i can't do it from command line is because i can't use my command line window for anything also, although i am such a newbie, i am sure there is a way.

I hope this helps.

ps: restarting the network-manager service, doesn't fix the problem. but the above does.

Take care, and let's hope this gets fixed soon.
