Which version of system do you use? Khadas official images, self built images, or others?

Please describe your issue below:

When I ran iw list, I noticed that many frequency bands were marked as disabled. In particular, all channels in the 5500–5720 MHz frequency band were disabled.

I also checked the dmesg logs and found an error indicating that the firmware file /lib/firmware/brcm/clm_bcm43456C5_ag.blob was missing.

Could this missing CLM file be the reason why the 5500–5720 MHz band is unavailable? If so, how can I enable this frequency band?

Hello @eunjee

Maybe you can try to change the country code to the country which supports such frequencies.
