Tplink Deco M4 — Mac Address Filter On

Before diving into the configuration process, it's essential to understand what MAC address filtering is. A MAC address is a unique identifier assigned to network devices for communication at the data link layer of a network segment. MAC address filtering allows you to create a list of devices that are allowed or denied access to your network based on their MAC addresses. This adds an extra layer of security to your network, making it more difficult for unauthorized devices to connect.
