On a computer with the Intel® 7265D wifi device iw reg get
produces the following output:

According to the output the wifi card seems to manage the regulatory domain itself.
The set country DE
is correct, but the information on the used frequencies and txpowers do not match the regulations for DE
.
On a another computer with a Intel® 7260 I get the following output and this is what I expect.
country DE: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 20), (N/A)
(5150 - 5250 @ 80), (N/A, 20), (N/A), NO-OUTDOOR, AUTO-BW

(5470 - 5725 @ 160), (N/A, 26), (0 ms), DFS
(57000 - 66000 @ 2160), (N/A, 40), (N/A)
This is the list I expect from reading the wireless-regdb
(see http://git.kernel.org/cgit/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt).
The problematic output for the 7265 was produced on computer running openSUSE Leap 42.1.
The crda
version is 3.18-5.1
and the version of wireless-regdb
is 2015.07.20-1.1
. Thus outdated versions cannot be the reason for this problem.
My guess is, that the output of iw reg get
is not correct for self-managed devices. This would explain the correct information in case of the 7260 module. According to iw
this is not self-managed.
Thank you very much.
P.S.: some information on the 7265D module
