Hello !
Thanks for help. But for now the result of your cat command returns "auto". I created b43.conf in /etc/modprobe.d/ with same permissions than others files in the same directory with content: options b43 hwpctl=0. I restarted. The cat command returns "auto" again. What is wrong ? Thanks again ! Hogren
