hy,
I tried to make an access point with 5ghz frequencies.
here a part of resultats of my iw list :
Frequencies:
* 5180 MHz [36] (23.0 dBm) (no IR)
* 5200 MHz [40] (23.0 dBm) (no IR)
* 5220 MHz [44] (23.0 dBm) (no IR)
* 5240 MHz [48] (23.0 dBm) (no IR)
* 5260 MHz [52] (23.0 dBm) (no IR, radar detection)
* 5280 MHz [56] (23.0 dBm) (no IR, radar detection)
* 5300 MHz [60] (23.0 dBm) (no IR, radar detection)
* 5320 MHz [64] (23.0 dBm) (no IR, radar detection)
* 5500 MHz [100] (disabled)
* 5520 MHz [104] (disabled)
* 5540 MHz [108] (disabled)
* 5560 MHz [112] (disabled)
* 5580 MHz [116] (disabled)
* 5600 MHz [120] (disabled)
* 5620 MHz [124] (disabled)

* 5680 MHz [136] (disabled)
* 5700 MHz [140] (disabled)
* 5720 MHz [144] (disabled)
* 5745 MHz [149] (30.0 dBm) (no IR)
* 5765 MHz [153] (30.0 dBm) (no IR)
* 5785 MHz [157] (30.0 dBm) (no IR)

* 5865 MHz [173] (disabled)
and here the resultat of iw reg get
