There is no specific function that activates the Wi-Fi only at certain times, such as from 7 am to 8 pm. However, you can adjust the network settings via the web browser-based configuration to secure the network and change the settings. To do this, go to the website https://www.mywifiext.net and log in to edit the settings. An external solution or a router with appropriate functions may be required for time-controlled activation of the WLAN.
