Is your feature request related to a problem?

802.11ac does not work if country_code is JP.

Describe the solution you'd like

I would like to be able to use 802.11ac even if the country_code is JP.

Describe alternatives you've considered

Additional context

802.11ac is allowed in Japan.

Follow this FAQ and report your Linux kernel version with uname -a.

Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux

Ekiben542 commented

The above output is from running uname -a.

Ok, check the FAQ. If you are able to start an 802.11ac AP with 'JP' we can look at adding it.

Where is the configuration directory?

Same for DE....one of the most famous model (https://avm.de/produkte/fritzbox/fritzbox-7590/technische-daten/) has AC included (as many many others..)

You are both absolutely correct. RaspAP has relied on its own internal database to set valid frequencies. This was intended as a short-term fix, but it requires updates with each revision of the kernel's wireless-regdb.

A better approach, I think, would be to parse the output of iw list and use this to set allowed frequencies:

sudo iw reg set JP
iw list
Wiphy phy1
...
Band 1:
    Frequencies:
	* 2412 MHz [1] (20.0 dBm)
	* 2417 MHz [2] (20.0 dBm)
	* 2422 MHz [3] (20.0 dBm)
	* 2427 MHz [4] (20.0 dBm)
	* 2432 MHz [5] (20.0 dBm)
	...
Band 2:
    Frequencies:
	* 5180 MHz [36] (18.0 dBm)
	* 5200 MHz [40] (18.0 dBm)
	* 5220 MHz [44] (18.0 dBm)
	* 5240 MHz [48] (18.0 dBm)

This should in theory make RaspAP's db obsolete.

I'll prototype a solution along these lines. Thanks for raising this.
