The FRITZ!Powerline adapter's Wi-Fi network cannot be switched off by pushing a button. The "WLAN·WPS" button allows you to set up Wi-Fi connections, but not switch the Wi-Fi network on or off.

If you are using the FRITZ!!Powerline adapter together with a FRITZ!Box, the FRITZ!!Powerline adapter automatically adopts the FRITZ!Box's Wi-Fi schedule during setup.

You can set up an individual schedule in the FRITZ!Powerline adapter if you want to switch off the FRITZ!Powerline adapter's Wi-Fi network and the FRITZ!Box's Wi-Fi network at different times or you are using the FRITZ!Powerline adapter with a router from another manufacturer.

You can also switch off the Wi-Fi manually under "Wireless > Radio Network" in the user interface of the FRITZ!Powerline adapter.
