Thanks for the hint. I am less looking for blocking access to my Wifi but for turning off the Wifi signal at night since I have the Orbi next to my bedroom but keep the wired internet running for some wired IoT devices.
@Voxel: Using your firmware with my RBK50 and it works just perfect!
Any chance for you to integrate the scheduling functionality to turn WiFi off at night eg based on a schedule? Unfortunately Netgear dropped this functionality a while ago and since them I am searching for a way by not...
