      Hello,

      I recently was trying to connect to rpi cm3 module and found that the wifi is no longer working.
      I tried to update wifi country through raspi-config but get "no interface found".
      I check that my wpa_supplicant file is set up correctly and it seems to be. File reads;

      ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
      update_config=1
      country=US
      
      network={
         ssid="my ssid"
         psk="my pass"
         key_mgmt=WPA_PSK
      }
      

      Wifi name and pass are correct, other devices can connect.

      /etc/network/interface file reads as;

      iface lo inet loopback
      iface eth0 inet dhcp
      
      allow-hotplug wlan0
      auto wlan0
      iface wlan0 inet dhcp 
      wpa-ssid "my SSID"
      wpa-psk "my pass"
      

      I saw that someone requested a dmesg readout to similar issue. I went ahead an ran. dmesg

      Any help would be great, thank you!

      retroPie version: 4.6.7
      Model: CM3
      Power: 3.7V 5200mah

        The CM3 doesn't have built-in Wi-Fi, unless the board where it's hosted has a Wi-Fi chip added. The dmesg output doesn't show any detected Wi-Fi interfaces, which looks normal for an out-of-the-box CM3 board.

          @mitu ah right, it's plugged into a Kite Circuit-Sword which has a wifi module attached to it.

            @ruttlehead In this case, using an OOB RetroPie image might not be enough and additional configuration may be needed to enable the Wi-Fi . You should contact the board's vendor/author(s) and ask how to enable it - RetroPie uses Raspbian Lite, there's nothing special added or removed from a stock Raspbian image.

              @mitu thank you for the response, wanted to double check there wasn't anything that could be done retropie side first. I'll reach out to utility board manufacturer.
