Thank you My question is do you have the used network card tuned off in bios?
in not you should start there.

Of course 12.04 is still in beta and may not fully support all controllers yet. but I would find it hard to believe that your VIA controller is not supported yet.

I ll' check but i think that is not disabled in bios because i am using it normaly under windows xp.I forgot to mention that i have a dual boot,and that the network manager is reporting : "Device not ready!" Thanks for the reply.

Yeah, I'm running into this too now. Suddenly network-manager can't seem to see the network, and the card isn't picking up . It is visible in ifconfig and it is loaded.. it's just not working. It was working last night.

install wicd via synaptic, it works smoother than network-manager

I had a problem, for several weeks, with >= Linux 3.2 not recognizing the pseudo, southbridge-driven, onboard LAN device on this computer.

The intermediate fix was to uninstall network-manager, and install Wicd, as dino99 recommended.

The long-term fix, was to install a NIC that Linux 3.2 / 3.3 supported... in my case a Netgear with a real DEC "Tulip" chipset, e.g. none of this cheapskate, pseudo device nonsense.

Network-manager works fine now!

I strongly suspect they removed support for many older LAN devices, in the most recent Linux kernels and/or Ubuntu Precise and/or the ancillary apps.

I would:

Run Wicd instead of network-manager (which I did)
Switch to a different LAN card (which I also did)


Both methods worked for me.

If you remove network-manager, you should still be able to connect to your router/modem manually using the following command:


sudo dhclient ethX

where ethX is your network device.

Yeah, tried that as well, and it just hung. Oh well. Might be the network card is going away, it's a JMicron (uses jme.o)
