Solved WiFi is not working on Pi 3B or Pi 3B+

@darth_joghurt what is your chip ?

[darth_joghurt]

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

[OyyoDams]

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

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

[darth_joghurt]

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

[darth_joghurt]

Do you need more information?

@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?

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 ?

@OyyoDams
Special caracter in wifi key ?

[darth_joghurt]

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

@darth_joghurt what is your wifi key encryption ?

[darth_joghurt]

@Scavy what do you mean with encryption?

[darth_joghurt]

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

@darth_joghurt great
