Hello, It returns alway "auto".
On the official Systemd documentation, I see that there is a new directory to say which modules load, but to change options, it's always with modprobe. I tried to modified the option on a command line, but, it's stay at "auto" : # modprobe b43 options hwpctl=0 # cat /sys/class/net/wlp36s0b1/power/control auto # modprobe b43 options hwpctl=1 # cat /sys/class/net/wlp36s0b1/power/control auto # modprobe b43 options hwpctl=off # cat /sys/class/net/wlp36s0b1/power/control auto What is wrong ? I really think that I use this module : # lsmod Module Size Used by x86_pkg_temp_thermal 4663 0 kvm_intel 148031 0 b43 385652 0 kvm 309648 1 kvm_intel irqbypass 2616 1 kvm sha1_generic 3067 0 For help, this is my kernel options about its : # grep -i "b43" /usr/src/linux/.config CONFIG_B43=m CONFIG_B43_BCMA=y CONFIG_B43_SSB=y CONFIG_B43_BUSES_BCMA_AND_SSB=y # CONFIG_B43_BUSES_BCMA is not set # CONFIG_B43_BUSES_SSB is not set CONFIG_B43_PCI_AUTOSELECT=y CONFIG_B43_PCICORE_AUTOSELECT=y CONFIG_B43_BCMA_PIO=y CONFIG_B43_PIO=y CONFIG_B43_PHY_G=y CONFIG_B43_PHY_N=y CONFIG_B43_PHY_LP=y CONFIG_B43_PHY_HT=y CONFIG_B43_HWRNG=y # CONFIG_B43_DEBUG is not set # CONFIG_B43LEGACY is not set CONFIG_SSB_B43_PCI_BRIDGE=y Thanks for help !
