Question about TP-Link Deco X50-5G (1-pack)

Yes, that is possible: The Wi-Fi can be automatically switched on and off at fixed times via the Wi-Fi schedule or ECO mode. When the schedule is active, all of the Deco's Wi-Fi networks are deactivated during this period, i.e., the main Wi-Fi, guest Wi-Fi, and IoT Wi-Fi; wired connections remain unaffected. A permanent, complete shutdown of the Wi-Fi is not supported, but a targeted hiding of the network is possible.
