cyril7: Hi for your requirement there is no need to use DFS channels, as others have mentioned wpa3 is likely the issue, either disable it on your current ssid, or stand up another ssid that is wpa2 only, personally for a home system, just drop the wpa3.

Thanks, but that means dropping 6GHz. Not an issue right now, but in future it might be. Or I should just create another SSID for the old stuff
Why do you need 6GHz?
