Does anyone know why can't I spoof my MAC in Windows Vista using SMAC (made by KLC consulting) or TMAC (Technitium)? I have a Realtek RTL8187L USB adapter (no-name, similar to Alfa AWUS036H?). When I try to spoof MAC, SMAC says that it is spoofed, but still reports the original MAC and ipconfig also reports the original MAC.
I also have two other Netgear PCMCIA adapters (WG511U and WG511) and both work fine, no problems changing their MACs.
Also under BT3 macchanger works fine. It is only Windows where I have a problem...
