How can I reset the MAC ID of my NIC?

Prashant Mirjankar March 12, 2013

Few days back I changed motherboard and to continue using Internet I changed the MAC ID of NIC on new board with the values from old NIC. Then yesterday I called the customer care (ISP) to register new MAC ID and delete the old one which they did.

But now the problem is when I cleared the MAC ID it is not obtaining its default MAC ID, but instead still using the MAC ID of old NIC.

How can I reset the MAC ID? I’ve already tried BIOS resetting.

Motherboard: GA-H61M-D2H

    -Highlight the number that match your network card, in the right pane look for the "NetworkAddress " key value. Right click on it and select modify . Enter the new MAC-Address.
    - If the key "NetworkAddress" is not in the right pane, right click in the blank space, select "New " then "String Value ". Enter the name "NetworkAddress ". Double click on it and set the desired MAC value.

    I expect you should reverse the original process you used to change your MAC since its probably in your Windows registry. When I change a MAC I use Technitium MAC Address Changer ( ) it's free and allows you to easily revert back to the original MAC give it a try it should give you some help.

    I expect your answer would be to reverse your original MAC changing process(Windows registry holds the new MAC). When I change a MAC I use TMACv6.0.3 ( and it allows for easy reversal.
