Dynamic:

Static:
This is called MAC Address Cloning
1. Open 'cmd' and type: 'ipconfig'
2. Look for your 'Default Gateway'. When you find it, it should look like
this.
3. Type the 'Default Gateway' into your address bar. Example: I would type in '192.168.1.1'. What this does is take you to your router settings.
4. Sign into it. The username is most likely 'admin' or 'administrator'. The password can be the following: 'admin', 'admin1', password', or 'password1'. If you have trouble signing in, contact your ISP.
5. Sign in and find 'MAC Cloning'.
6. Click on the 'MAC Cloning' tab or icon.
7. It should look like
this after you have clicked on the tab or icon.
8. Change it to anything you want. I always choose to add '1337' somewhere into there for the lulz.
9. Click 'Clone MAC Address' or 'Done'. Something similar to completion.
