Hi, the ath10k module sets the country code to US at initialization. After that the country code cannot 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. Re-compiling every kernel-update isn't an option on production systems. :-( 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 See http://forums.debian.net/viewtopic.php?f=5&t=141402&p=695556 for further details. Regards, Renne
