Can't setup Wifi connection

Hi, I’m using version 8.2, i installed the supervisor and in the host menu i could setup the wifi, setup the password it even gives me a IP adress.


He says i am connected, but when i unplug the ethernet i cant find the page.

I tried making a file called network en put it on my raspberry with a usb stick. That didnt work this time :confused:

Any idea what I do wrong?
