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

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 ?

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?

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
