and brcmfmac WiFi Firmware version = wl0: Dec 15 2015 18:10:45 version 7.45.41.23 (r606571)
only support Channel 01 - Channel 11 (no Channel 12 + 13)
==============================
It’s a kernel bug and the hardware does not support channels 12 & 13 in Germany. Kernel 4.4 apparently fixes it.
Can you help me with upgraden the kernel in DietPi?
IMPORTANT: - Only for Testing ! - :
- Upgrade to the latest Kernel and Firmware (not recommend to do this !!!)
root@RPi-3-test:~# dietpi-config
=> 4 Advanced Options
=> 4 Update Firmware
=> reboot
