To permanently change the MAC address of your WiFi card, you need to modify the system's network configuration files. The specific method varies depending on the operating system you are using, but here are some general steps:
Determine the interface name: Run ifconfig to see a list of all network interfaces on your system. Identify the name of the interface you want to modify (e.g. wlan0).
Modify network configuration files: The location and name of the network configuration files can vary depending on your operating system and distribution. In most cases, you can find the network configuration files in the /etc/network directory. Open the configuration file for the interface you want to modify (e.g. /etc/network/interfaces), and add a line to set the MAC address:
auto wlan0
iface wlan0 inet dhcp
hwaddress ether ab:ea:5a:a3:bc:01
Replace wlan0 and ab:ea:5a:a3:bc:01 with the appropriate values for your system.
Restart the network interface: Run ifdown wlan0 followed by ifup wlan0 to restart the interface and apply the new MAC address.
Test the new MAC address: Run ifconfig and look for the interface you modified. The MAC address should be the one you set in the configuration file.
Note that changing the MAC address of your network interface may be a violation of your network provider's terms of service or local laws. Use this information responsibly and only for legal purposes.
