Some ISPs require that you register a MAC address. This feature "clones" your network adapter's MAC address
onto the Router, and prevents you from having to call your ISP to change the registered MAC address to the
Router's MAC address. The Router's MAC address is a 12-digit code assigned to a unique piece of hardware for
identification.
Enter the MAC Address in the User Defined MAC Address field for Internet ports 1 or 2, or click the Clone button
to add the MAC Address from the PC viewing the Web-based Utility.
Click Save Settings to save the MAC Cloning settings or click the Cancel Changes button to undo your changes.
