Restoring the Network-Manager applet in Ubuntu

So you’ve noticed the Network-Manager applet is missing from your notification area in Ubuntu and you can’t connect to your wifi or cellular network. Now what?

Here’s a few tips to get it back, based on Ubuntu 10.10:

1) Make sure Network-Manager applet is installed

Open Applications > Ubuntu Software Center
Type ‘network’ in the search box and hit enter.
Locate ‘Network Manager’ in the application list and make sure it has a green check mark next to it.

2) Make sure Network-Manager-Applet is set to run on start-up

Open System > Preferences > Startup Applications and make sure the box next to Network Manager is checked.

The next two tips are slightly modified tips provided from UbuntuGeek:

3) Make sure Network-Manager is managing your connections

Open the terminal and type:

gksu gedit /etc/NetworkManager/nm-system-settings.conf

change the “managed=false” to “managed=true” and then save it.

then in the terminal type:

killall nm-system-settings

and then reboot.

4) Re-add the notification area to your bar:

right click panel>add to panel>Notification Area

5) Two bugs reported to LaunchPad involve this. Bug #577678, and #589362. Regarding #577678, a user suggested this fix:

Open a terminal and type:

gksu gedit /etc/network/interfaces

then check that the file has only this 2 lines:

auto lo
iface lo inet loopback

Delete all the others then reboot.

6) You may also want to try restoring the panels to default.

    When I did the “killall nm-system-settings”, I got in return “no processes found”
    I also seem to be unable to add “right click panel>add to panel>Notification Area” as it seems to be there already
