You're right! I tried it here too: # modprobe -r b43 # modprobe -v b43 options hwpctl=0 insmod /lib/modules/4.4.39-gentoo/kernel/net/wireless/cfg80211.ko.gz insmod /lib/modules/4.4.39-gentoo/kernel/net/mac80211/mac80211.ko.gz insmod /lib/modules/4.4.39-gentoo/kernel/drivers/ssb/ssb.ko.gz insmod /lib/modules/4.4.39-gentoo/kernel/drivers/net/wireless/b43/b43.ko.gz qos=0 options hwpctl=0 However, it doesn't seem to report this when I look at the sys entry, just like yours: $ cat /sys/class/net/wlan0/power/control auto Even if power control reported as auto (perhaps some other kernel setting imposes this) as long as the power control setting (0 or 1) help your problem then use it. If it is ineffective remove it and let the kernel do its own thing. Did you increase verbosity and have you checked your logs and dmesg to see if there is anything reported when connection is lost? -- Regards, Mick
