The error usually stems from how modern network drivers and the Windows operating system handle .
Type a new 12-character hexadecimal string without dashes or colons. Ensure the second digit is 2, 6, A, or E . Valid Examples: 021122334455 (Ends in 2) 06AA00112233 (Ends in 6) 0A1234567890 (Ends in A) 0EABCDEF1234 (Ends in E) 4. Apply and Refresh Click OK to save the changes.
Unlike Ethernet adapters, many modern wireless drivers and Windows versions (Vista and later) impose strict restrictions on MAC spoofing.
Whether an address is universally administered (assigned by the manufacturer) or locally administered depends on the (the first two digits). Specifically, the second hexadecimal digit of the first octet controls this property. The error usually stems from how modern network
Starting with Windows Vista and 7, drivers for many Wi-Fi cards (such as those from Intel or Realtek) strictly enforce the IEEE 802 standard
If the combination of characters you chose does not follow the rules for a Locally Administered Address, the driver rejects the change, resulting in the "Failed to change MAC address" error.
Click the radio button on the right to expose the text field. 3. Insert a Compliant MAC Address Valid Examples: 021122334455 (Ends in 2) 06AA00112233 (Ends
A MAC (Media Access Control) address is a unique 48-bit address assigned to a network interface controller (NIC) for use as a network address in the data link layer of a network segment. It's often referred to as a physical address or hardware address. MAC addresses are usually represented in a six-octet format, separated by hyphens or colons, like this: 00:11:22:33:44:55 .
