Why does the current router firmware not support MAC address white listing? This has been a basic feature of consumer home networking for years.

Parental controls (that require a paid subscription) do not work consistently if client devices are able to change MAC addresses. Turning off MAC address changes on the client is NOT a solution unless one has very young children. Remember, this generation of young people has grown up with technology from a very young age.

When will TP-Link add this to their firmware?
