Would have been nice to have some info about the relevant components directly in the subject. And iw is not that relevant - it is just a tool which you used to inspect the state of the system.

But the kernel might use it - like in your example. Unfortunately, the previously mentioned firmware includes an own regulatory db which is then used for the phy0 ("self managed"). But the commit at least provides some good reasons why Intel might consider enabling the indoor channel in the frequency range 5945 - 6425 MHz. It would therefore be nice to know whether/when Intel actually has plans to enable these channels in Germany (and not only for the US) in the near future. Maybe there are even newer (test) firmware versions available but I am not aware of any newer firmware version than the previously mentioned one [1]. And this firmware was published for linux-firmware right around the time when Vfg. 55/2021 was released - so it is to some extend expected that Intel didn't yet incorporated such a change. I only saw newer releases for other HW [2] but not for Ty.
