Hi,

Archer AX73 supports Access Control, which is used to block or allow specific client devices to access your network (via wired or wireless) based on a list of blocked devices (Blacklist) or a list of allowed devices (Whitelist).

For more information, please refer to Archer AX73_V2_User Guide.

Your screenshot shows it works in AP mode. It does not support Access Control in AP mode.

What’s the difference between the Access Point Mode and Router Mode on the TP-Link wireless router?
