      Hi,
      I posted the same thread at the german forum two days ago. Since there was no response until today I try to reach more people at the international board. Sorry for double posting and for my bad english.

      Here is my problem:
      I can connect to the Internet via LAN but not via Wi-Fi. I've tried several ways on Pi3 and 3+.
      Here is what I've tested already :

      -SSID without special characters, once with spaces, once without spaces.

      -Password without special characters.

      -Registration via UI (SSID is found, connection is not possible).

      -Log in via Manager (saves the settings, but does not connect).

      -Login over the .conf (saves the attitudes, but does not connect) the semicolons before the SSID and the key removed thereby also, the Country code I put on DE, wifi enabled I set to 1.

      -The SSID on the router is visible, the security key is WPA2, the channel I have set to 8 testwise (normal would be auto, but that's not working too)

      So I hope I did not forget anything.
      After each change of settings, I rebooted the Pi, to no avail.

      I tested all settings with both Pi's (3b and 3b +).
      I do not know what else I can test. I hope you can help me.
      Btw, the WLAN chip works on both Pi's, because with other operating system everything works perfectly.

          Sorry I don't understand your question. Is it possible that I have a different chip on my pi3 than on yours?

            @darth_joghurt sorry I thought you were using an external chip.

            In recalbox.conf, try to set wifi.region=DE

              No I'm using the internal chip.
              As I described in my opening post I already set the country code to DE.

                  @darth_joghurt Which version of Recalbox are you using?
                  Have you set up the system yourself, or are you using a ready-made downloaded image from the internet?
                  Are you sure that the wifi did not connect? In my RPi3, sometimes when turning on the wifi shows as disconnected, but I can access the recalbox manager by the smartphone without any problem, you were only based on the information "disconnected" or tested?

                  Se a minha resposta foi útil, por favor, dê um voto positivo, clicando na seta para cima logo abaixo da resposta, ao lado de "citar".
                  If my answer was helpful, please give a positive feedback by clicking the up arrow below the answer, next to "quote".

                    Hi, I had problems by configuring my 2,4 GHz WiFi using channel 12 and 13. At least with Pi3 B and latest Recalbox stable. Seems that Pi (or Recalbox?) does not support these channels.
                    Maybe this helps...

                      Hi, I used the latest stable version for the 3B and the Christmas-beta for the 3B+. I've set up the systems by myself, no pre-made images from the internet.
                      The connection was testet by trying to get access through the manager.
                      I've already changed the wifi channel to 8 but that didn't work too.

                        @darth_joghurt is the SSID is found, it means wifi works and your router is seen by Recalbox. Besides, for an unkwnown reason yet it cannot connect, and I bet it's password related, or maybe some security on your router side. Just WPA2 ? Not enterprise preshared key or something like that ?

                            No there are no special security settings on my router. My password is only numbers. All devices are allowed to connect to the router.

                                  Hi guys, I have solved the problem. I thought I had the function "only allow known devices in the Wi-Fi" disabled and set to "allow all devices". Unfortunately, my router has not adopted the setting. After I changed it, everything worked
