The first octet must be 02, 06, 0A, 0E, 12, 16, 1A, 1E, 22, 26, 2A, 2E, 32, 36, 3A, 3E, 42, 46, 4A, 4E, 52, 56, 5A, 5E, 62, 66, 6A, 6E, 72, 76, 7A, 7E, 82, 86, 8A, 8E, 92, 96, 9A, 9E, A2, A6, AA, AE, B2, B6, BA, BE, C2, C6, CA, CE, D2, D6, DA, DE, E2, E6, EA, EE, F2, F6, FA, FE – but in practice, most drivers accept only even values for the second hex digit: 2, 6, A, E . In most cases, simply changing your target address
This is why the error message itself points you to this solution, and it's why tools like TMAC have an option to enforce it. While advanced methods like the Network Bridge exist, they add complexity and instability for a benefit that is often purely aesthetic or trivial. In most cases, simply changing your target address to a valid LAA is the only reliable, permanent fix you need. If this is toggled "On" in your Wi-Fi
Setting the second character to 2, 6, A, or E ensures this "local" bit is correctly flipped to 1. For example, a MAC address starting with
Fixing "Failed to Change MAC Address" for Wireless Connections
Windows has a built-in "Random Hardware Addresses" feature. If this is toggled "On" in your Wi-Fi settings, it may conflict with your manual attempt to set a static spoofed address. Ensure this is turned off before applying your own. 3. Registry Permissions
