I am trying to spoof the MAC address of my new Win7 laptop. To do so I tried specifying an alternate value from the Device Manager which took no effect. I also tried from the registry, as per other threads here, to no avail. Interestingly I also found the registry contained a path 000X\Ndi\params\NetworkAddress\default REG_SZ, but changing that had no effect either :(

I can only guess I share the same issue here: as the wireless adaptor is the same brand bundled with the same operating system. So my question is - is there anything better I can do to achieve a spoofed physical address than rollback the drivers to some older version?

Have you tried turning the adapter off and on again? (Alternatively, reboot.) – grawity May 21 '11 at 19:41
@grawity - several times, both ways. – lpd May 22 '11 at 7:32
@00101010 I installed SMAC and promptly installed after it told me it could only change the mac address to one predefined string unless I paid it forty bucks. The other link specifies it only works up to Vista... I'll give it a go later but I doubt that it'll work unless someone has specifically programmed a way to avoid this extra "security". – lpd May 22 '11 at 7:37

Just install CommView for WiFi. You don't have to know what does that program. But it will change your WiFi adapter's driver and let you change it's MAC address from adapter's settings.

To do it, download and install that program, go to WiFi adapter's properties -> Configure -> find "Network Address" or "MAC address" or "Physical Address" and change it.
