This bug needs to be forwarded to, reported upstream against Network Manager (NM) otherwise chances that it will ever get fixed are even lower if it is only reported here.

A friend running 12.10 and myself running 12.04.1 both experienced the same problem. Using the following series of commands to change the ethernet MAC address works fine under some specific circumstances: ifconfig eth0 down ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx ifconfig eth0 up If there is a wired connection defined in the network-manager gui (click the wireless signal-> Edit Connections...) and there is a Cloned Mac Address defined in there, the MAC address of eth0 WILL REVERT to it's original (hardware) MAC address upon connection of an ethernet cable. This is very strange and frustrating. In order for the above MAC address changes to take effect, there needs to be nothing filled in with the GUI. Second issue (I guess it is related) is that if everything is working correctly, the MAC address WILL REVERT to it's original (hardware) MAC address upon DISconncetion of the ethernet cable. Perhaps I am doing something horribly, horribly wrong here, but it's frustrating and hours of searching the forums have not given me any indication of the correct place/time to change MAC address. If network-manager does not want to respect the changes I have requested, then it should at least provide a functioning, documented alternative method in order to make the same change. What I would expect: Changing the MAC address of eth0 using the network-manager gui will actually change the MAC address everytime the interface is brought up. Current workaround: In /etc/rc.local, run the above commands for changing hardware address In /etc/network/if-post-down.d/ create a script that will sleep for 5 seconds and then run the above commands.
