NetworkManager cloned mac is brocken

Cloned mac line take no effect according to ifconfig output. How to fix it? Is this a bug?

I’m not sure if this will help in your situation, but it’s worth a shot.

This is an excerpt from an askubuntu tagged hot answers post:

[quote]1: dhclient -r to release the dhcp lease

2: remove all the dhcp lease files from /var/lib/dhcp/

3: edit /etc/network/interfaces to change the hwaddress line to something random, restart network and repeat several times, then finally restore the cloned mac address and restart network.[/quote]

This may help as well:

Of course not. This is not about how to change it actually. But how to make it works through NM. Because I remeber it had work not so long ago. Weird that this have no effect now.
