I am trying to change my MAC address with several pieces of software that should do the trick, but they don't. They assign a new address, restart the controller, but the MAC address is still like it was before.
What could be the problem?
I have ASUS MB built in Realtek RTL8168C controllers.
I don't know because mine is initially empty, but I haven't tried to change it with unknown utilities. getmac on a Gigabyte motherboard returns 00-1F-D0-xx-xx-xx. On an Asus motherboard, it returns 00-22-15-xx-xx-xx. What did you expect?
