How do I change the MAC address of my WiFi antenna?

    Hi,

    I have a laptop running Windows 7, and it has wireless capability as well as an Ethernet jack for wired internet connectivity.

    Both have MAC addresses that I've managed to change by running small powershell scripts I've written.

    The scripts go into the registry and change the network addresses.

    I then disable and re-enable the devices in device manager, and the new MAC addresses are reflected when I call ipconfig /all in powershell.

    Now, I have a brand new WiFi antenna I just purchased, a Signal King SK-11TN.

    I've tried to do the same exact thing to change its MAC address, but to no avail.

    The MAC address stays the same in ipconfig /all no matter what I do.

    What am I missing?

    It's more associated to the NIC than the antenna. If the driver of the card doesn't support spoofing then it likely won't play with your settings.

    You could verify by booting into Linux and trying to use macchanger.

    The NIC?

    The NIC is irrelevant apparently.

    I can disable the wireless adapter and just use the antenna by itself.

    It plugs into a USB jack but is listed under network adapters by the OS.

    I'm using WIN7 by the way.

    Do you think that the antenna's driver won't accept any software override for the antenna's MAC?

    The 'antenna' is its own USB NIC.

    OK, got it.

    So you think the problem is with the driver?

    Anyway to take the driver's executable, open it with a binary editor, disassemble it, re-write it to allow for MAC override, reassemble, and reinstall?
