Dear intel wireless maintainers,

I am on kernel version 6.3.1 with a Intel AX200 (8086:2723) WLAN device on firmware version 71.058653f6.0 (see details below). I am in Switzerland and the country code is also set by the device (see output of iw reg get below). But the regulatory domain information is wrong, i.e. i.e. in some bands the allowed transmission power is wrong (e.g. 5725 - 5875, compare with the info frow iw reg get under global or the official information under https://www.ofcomnet.ch/api/rir/1008/12). Since the device is self-managed, the correct information from the regulatory domain database is not used. Can the deviced be forced to use the correct regulatory domain information from the database or the self-managed values be changed to be correct?

With best regards,
Julian Wollrath
