No network connection information

**ammofreak** · May 30th, 2012

Hi

Now using Ubuntu 12.04LTS with Unity desktop on my Dimension 8400. My question: although I have a network connection (wired), the Connection Information in the Network applet menu reveals no info other than "Error displaying connection information: No valid active connections found!". I am not overly concerned about this but I am curious as to why. Have already done the basic
T/S. If anyone has had a similar problem & solved it, I would appreciate the I/P. Thanks in advance....

You can retrieve all the network information of the wired interface by issuing the following command on a terminal .
Press alt+ctrl+T

Code:

ifconfig

TY for the post! However, I am more interested in finding out why the connection info does not work from the applet. I appreciate your I/P. TY again...

Hi everyone

Found the solution: interface appears in /etc/network/interfaces. By default, NetworkManager does not manage interfaces that appear in /etc/network/interfaces. One can change this behaviour.

To do this - in a terminal:

sudo nano /etc/NetworkManager/NetworkManager.conf

change the line managed=false to managed=true

Save, stop and start network manager:

sudo service network-manager restart

Hi,

I hope you have tried this. But let us make sure that you have done this before proceeding further.

If that is the problem, then please re-install the drivers.

Sorry for resurrecting a old thread but I just wanted to say thank you. I was installing ubuntu on a older computer and I was having this issue and this fixed it! THANK YOU!
