Ubuntu 9.10 Network: device not managed

Hi,

I suggest this procedure to replace NetworkManager with wicd:

First connect your network card to the wireless router using a LAN cable.

Then please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy-paste each line below to the Terminal then hit <enter> after each line)

sudo aptitude update
sudo aptitude install wicd

Step 3: Please post results (copy/paste terminal output from each command) on this thread

You can read more about wicd here: http://en.wikipedia.org/wiki/Wicd_(Linux_Network_Manager)

Then reboot and you should then see a new wicd icon appear in the Ubuntu panel (wicd Linux network manager icon)

Regards,

Mark

Your interface4 is still configured by the old network setup system of 8.04.
You interface should be listed in /etc/network/interfaces.
If everything works fine you do not need to change anything. But if you want to have Network Manager handeling the conenction you can reduce /etc/network/interfaces to:

auto lo
iface lo inet loopback

In the /etc/NetworkMananger/nm-system-settings.conf should be managed=true under [ifupdown]. What is the content of your local file?

If it is not broken don't fix it.And +1 to Thomas Krüger

@Mark Rijckenberg - thank you, but i don't like wicd and my problem doesn't involve wireless
@Thomas Krüger and @Cristi Nistor - i've tried both your suggestions, it didn't changed anything unfortunately

So i've just gived up, it's working fine for the moment .

Thank you all for the answers.

I have the same issue for my DSL connection. After pon dsl-provider command the connection is up, even the network manager shows that is disconnected. If I connect it directly to the Internet it shows correctly the status. But, I think I'll live with it as it is.

I also have this problem, both on wired and wireless. No connection on either.
