Continuing the discussion from Not Able to Connect to WiFi with Octopi:
I have the same problem with the wifi connection. I recently bought a Raspberry Pi 4B and firstly tested it with the o.s. loaded on the included sd card. In this case the wifi connection worked correctly.
Then, I tried to install Octoprint on a different sd card and i have realized that the network was not able to see the pi (octopi).
Did you solve this problem? Please, is there someone who can help me?
