What is the purpose of MAC control on a Wi-Fi network?

The purpose of MAC control on a Wi-Fi network is to allow only certain MAC addresses onto your wireless network. This security measure is implemented to enhance the control over which devices can connect to the network. Each device that connects to a network has a unique Media Access Control (MAC) address, and by configuring MAC filtering, network administrators can create a whitelist of allowed MAC addresses.

When MAC control is enabled, only devices with corresponding MAC addresses on this list are granted access. This helps reduce unauthorized access and can thwart some of the common threats to network security, such as unauthorized users attempting to connect to the network. While MAC filtering is not foolproof—because MAC addresses can be spoofed—it provides an additional layer of security that, when combined with other measures, can help protect the network more effectively.

This focus on device-specific access control through MAC addresses is key to maintaining a secure and managed Wi-Fi environment.
