I'm using ubuntu 12.04 LTS. Recently my ISP changed my MAC address and I changed it accordingly from "edit connection". But after editing the MAC address of an existing connection it no more appears in the Wired Network list. If I add a new connection it doesn't appears in the list.

How can I bring a connection to the Wired Connection list?

I suspect you really shouldn't have changed anything. You sure your ISP told you to change it? –  Braiam Feb 14 at 2:27
    
On some ISPs you have to have a specific MAC address to connect. It's entirely plausible changing it was actually required. –  Olli Feb 17 at 17:01

You can try to solve your problem by following this link http://www.upubuntu.com/2012/04/how-to-change-mac-address-on-ubuntu.html

Good luck and keep us updated


To follow @fleamour's advice, here is the gist. First, stop the network manager with this command: sudo service network-manager stop

To change the current MAC address, run this command: sudo ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx and replace xx:xx:xx:xx:xx:xx with your own MAC address.

Next, restart your network manager with this command: sudo service network-manager restart and then check your network interfaces to see if the new MAC address (es) is well enabled with sudo ifconfig -a
