Isn't it illegal to change mac address?

  No. Half the number space is free for local management.

  At most you'll annoy your internet service provider. MAC addresses don't leave the immediate network they're used on, so you can do whatever you want within your home network.

    How would your ISP even know unless they are spying on data only available on your wifi network with an ISP provided router?

      I spoof my router's MAC address to change my external IP address at will. But yeah, hopefully they can't see the MAC addresses on your local network.

  Why? You may well need to do this in case of Address Clashes. Its not unknown for a manufacturer to mess up and reuse MAC addresses.
