Wireles-regdb.

The question concerns computers with WI-FI.

Devuan Daedalus, when loading there is a pause to search for regulatory.db.
This is a database with the conditions for using WI-FI in a specific user's country.

It is in the optional

wireles-regdb

package, which must be installed.

Otherwise, the user may turn out to be a criminal by accidentally turning on a WI-FI channel that is prohibited in his country.

Re: Wireles-regdb.

On my system the wifi regulatory database file name may be found...

This file comes from the firmware package for my intel-wire-less wifi (iwlwifi).

This file may be stored on a memory stick and inserted for install, the installation program will usually find it and load it while telling you so.

If you use the wrong one, it just won't work properly.

see how you go.

ps. the installation will continue with out wifi (for updates). My system asks for it but it's built-in now.

Re: Wireles-regdb.

My post is not about the Wi-Fi card driver.
Quote:
"Linux allows changing regulatory domains in compliance with regulatory restrictions world wide, including the US FCC. In order to achieve this devices always respect their programmed regulatory domain and a country code selection will only enhance regulatory restrictions. This is in accordance with the FCC part 15 country code selection knowledge base publication number 594280. As an example if your device was programmed for operation in the US which allows operation on channels 1-11 on the 2.4 GHz band and you visit Japan which allows operation on channels 1-14 and you change your regulatory domain to JP you will not be able to use channel 12, 13 or 14 (CCK). But if you have a device programmed for operation in Japan and visit the US and you select US as your regulatory domain you will have channel 12-14 disabled..."

Re: Wireles-regdb.

This database isn't present on my main computer (only LAN), but on my laptop its installed as well in Chimaera as Daedalus.

If I am not mistaken the wireless-regdb is installed with wifi drivers and firmware as a dependency. At least this was happening when installing the laptop. I guess there are dependencies.

Re: Wireles-regdb.

I don't think it's criminal, it simply won't work the same in every country.

The worst that could happen is "no connection", imho.

Re: Wireles-regdb.

The situation is obvious, the package is not tightly linked to other packages, is not installed by default, and apt does not object when it is removed.

Although the kernel still looks for it when loading.

Whether this is good or bad, as well as the issue of responsibility for the use of prohibited radio frequencies, is up to the developers to decide.
