Unable to change Wi-Fi country code Topic is solved

[iFelix18]

Trying to change code via DietPi-Config I get the following error on RPi 4 Model B (aarch64):

Code: Select all

[FAILED] Country code "IT" could not been applied.
Please check the country code and try again.
If problems persist, this may be a limitation with the driver/chipset.

Hi,

many thanks for your message. I tried to replicate your issue but for me this is working well. I did it as well on RPi4B 64bit

Code: Select all

root@DietPi4:~# dietpi-config
[ SUB2 ] DietPi-Set_hardware > wificountrycode (it)
[  OK  ] DietPi-Set_hardware | Setting in /etc/default/crda adjusted: REGDOMAIN=IT

I made a fresh install. I have preconfigured the WiFi as explained here.

Changing the code this is what I am shown:

After that I get the error reported in the first post. After rebooting, the code is "DE".

[Joulinar]

where do you have the error message? because the output looks fine

[iFelix18]

I found the answer apparently. As explained here "the kernel module cfg80211 is able to get regulatory information by an acess point, if it is associated with it", and as explained here on the forum of the manufacturer of my access point "All the Deco EU version products use DE as country code". That's why I couldn't set a country other than DE.
