Hi,
I posted this to the linux-wireless mailing-list 4 days ago and did
not receive an answer.
The ath10k module sets the country code to "US" at initialization.
After that the country code can't be changed anymore (e.g. to "DE").
Compex support suggests setting "reg->country_code =
CTRY_UNITED_STATES;" in "/drivers/net/wireless/ath/regd.c" to the
local country.
Patching and re-compiling every kernel-update isn't an option on an
UEFI-only production system.
Kernel version: 4.19.0-4-amd64 #1 SMP Debian 4.19.28-2 (2019-03-15)
x86_64 GNU/Linux on Debian 10 Buster
The WLE900VX is based on the QCA XB140 reference design.
Until Thursday we have the option to return the cards to the dealer.
Thanx for any hint,
Renne
