Explanation

MAC (Media Access Control) filtering allows the router to maintain a whitelist of approved MAC addresses - the hardware-level identifiers burned into each network interface card. Only devices whose MAC address appears on the whitelist are permitted to connect. This directly addresses the scenario: an unauthorized device (likely a neighbor) was connecting to the user's Wi-Fi and using it to download copyrighted content. WPA/WEP passwords help but do not restrict access to specific known devices. Static IPs alone do not prevent unauthorized devices from connecting.
