@Gigi20 Have you already tested whether configuring the parameters for wifi in
recalbox.confdo not work for this situation?
The parameters are:
;wifi.ip=manual ip address ;wifi.gateway=new gateway ;wifi.netmask=new netmask
There is still this tutorial, but it may be out of date:

And, for some users, the easiest is to configure it on the internet router, and set the IP by the Rpi MAC address.
Thanks, I give it a go to figure it out.
