Whenever I freshly install Ubuntu I face this Network problem. The Network Manager says that no wired connection is connected. It says that this device is not managed and I wont be able to connect to internet. Here is a workaround that fixes this problem.
Open terminal and type the following :
sudo gedit /etc/NetworkManager/nm-system-settings.conf
and hit enter. Now text editor will open nm-system-settings.conf. Find the line managed=false and replace false with true and save the file (ctrl+s) and close the file. Restart your computer. The problem will be solved.
Things to remember :
There is no space in the string /etc/NetworkManager/nm-system-settings.conf.
The command is case sensitive, so type the string as it is.
If this workaround didn’t worked for you then try another workaround about which I have posted. You can see it here.

It’s Working for me. Thanks a lot!
The problem came out after I used wireless connection. Wireless worked well, wired all vanished, and I can’t use wired connection any more. It bothered me a lot. Now everything is ok!
I can shift smoothly between wired and wireless by left click on the icon! No restart needed.
thank you for your tips in detail, Samuel!
Thanks man, this really worked
Glad it worked for you Marius.
Thank God for the ubuntu live cd that booted me with a connection and thanks to you I fixed this.
At college i have router automatic connection, but home I have pppoe, and when i went in vacation i had to use pppoeconf, which seems to screwed up with my settings. Now when I came back to the campus, I was in shock, thinking of reinstalling to fix this crap, and I’m so lazy when it comes to backing crap up and doing a clean install.
You saved my as$, thank you! thank you! thank you! thank you! thank you!
You are welcome Moooooo… Ubuntu 9 has made significant changes in both positive and negative ways (issues like this). Let’s hope that Ubuntu 10 fixes them all.
Is it still unmanaged? where exactly are you facing the problem?
That’s OK Leo! I am also new to Ubuntu and I posting articles keeping in mind how a newbie thinks and what problems will newbies face. I am glad that this helped you. Enjoy Ubuntu!
