Problem setup Daikin wifi module

hello everyone,
I have a problem to connect the Daikin wifi unit BRP069B45 with my home network.
When I use the setup WPS procedure, a connection is made. The RUN light is on. But my wifi network is offline. All I can do is reset the router. After that, the connection with the WiFi module is broken again.

When I use AP mode I manually set up the connection. I then see that the connection has been made, but not on my home network. I then get the error code that there is no internet connection.

Who can advise me on what to do to set up the connection?
