#86978 — Bug#1104022: wireless-regdb: Consider importing setregdomain and udev rule from Fedora

Package: wireless-regdb
Version: 2025.02.20-1
Severity: wishlist
X-Debbugs-Cc: debian@voltagex.org

Dear Maintainer,

Fedora (and others?) have an additional script and udev rule as part of the wireless-regdb package
which attempts to set the wireless country code automatically.

See https://src.fedoraproject.org/rpms/wireless-regdb/tree/rawhide


   * What led up to the situation?
$ sudo iw reg get
global
country US: DFS-FCC
        (902 - 904 @ 2), (N/A, 30), (N/A)
        (904 - 920 @ 16), (N/A, 30), (N/A)
        (920 - 928 @ 8), (N/A, 30), (N/A)
        (2400 - 2472 @ 40), (N/A, 30), (N/A)
        (5150 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW
        (5250 - 5350 @ 80), (N/A, 24), (0 ms), DFS, AUTO-BW
        (5470 - 5730 @ 160), (N/A, 24), (0 ms), DFS
        (5730 - 5850 @ 80), (N/A, 30), (N/A), AUTO-BW
        (5850 - 5895 @ 40), (N/A, 27), (N/A), NO-OUTDOOR, AUTO-BW, PASSIVE-SCAN
        (5925 - 7125 @ 320), (N/A, 12), (N/A), NO-OUTDOOR, PASSIVE-SCAN
        (57240 - 71000 @ 2160), (N/A, 40), (N/A)

I am not in the US and I belive this is contributing to some of my issues with wifi.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

"options cfg80211 ieee80211_regdom=AU" | sudo tee /etc/modprobe.d/mt7921.conf


   * What was the outcome of this action?
   * What outcome did you expect instead?
Wireless regulatory domain / country code to be set automatically


Regards,
Adam

Disclaimer, I have not checked how suitable the respective script in
fedora is, but as alternative I would propose that you might ask
Fedora people to submit their adaptions to upstream (even if only
provided as examples, there are already e.g. spec file or a
debian-exmaple directory upstream). Once it is there it would be more
streamline for distros to have a common base .

I'm not sure if this alternative road would be suitable, but proposing
an alternative road. Let's see what Ben thinks on it.

Salvatore

#88970

I'd like to add to this that while it would be great if those scripts/rules could be added, they don't seem to be able to work for every WiFi module. I'm on an Intel AX210, all methods fixing the output of 'iw reg get' fail, via 'iw reg set', through modprobe options or whatever. So probably there is the need to indicate when a WiFi module will just plain out refuse to set the correct regdomain, maybe that can put enough pressure on vendors like Intel to get their stuff into a working state.


Best regards

Richard

In version 2026.02.04-1 I have added a script and udev rule to set the
country code.  However, they require manual configuration because I
don't think it's correct to infer the regulatory domain from time zone:

- The system time zone doesn't necessarily reflect its actual location
- Time zones can cross country boundaries
- Even where this works, there was no provision for handling changes of
time zone

I documented how to configure this in README.Debian, as well as the
limited usefulness of doing so.

Can I close this bug report?

Ben.
