Network applet not visible and unable to edit network settings

[pratik_narain]

I have just now installed a new copy of ubuntu 14.04.1 LTS. When I try to open the Network item in system settings it gives me an error message:

The system network services are not compatible with this version.

I am using a wired lan connection and internet is working. I just can't change the settings and there is no network applet on the panel.

Try command

nm-applet & disown

in terminal, as I have just noticed there is no run box from Alt+F2 when using unity, which is what I was going to suggest.
