On Net the NetworkManager log shows (wlp0s0): using nl80211 for WiFi device Control device (wlp0s0): driver supports Access Point (AP) mode manager: (wlp0s0): new 802.11 WiFi device device (wlp0s0): state change: unmanaged -> unavailable (reason 'managed') [10 20 2] More interestingly # wpa_supplicant -Dnl80211 -iwlps0s0 -c/etc/wpa_supplicant/wpa_supplicant.conf Succesfully initialized wpa_supplicant rfkill: WLAN hard blocked So, on my netbook, when it turned on, the wifi was always not quite right and I had to toggle via the via function keyboard key it to 'off' and then 'on' again. That not working could have been part of the problem under 4.9.35? But for this laptop, that had never been a problem, the wifi worked. Still, I've tried now toggling it using the Wifi function key and no success Sadly the rfkill command doesn't seem to be available in my dom0 or net vm In net tried (after chmod u+w hard) # echo 0 > /sys/class/rfkill/rfkill0/hard Error while writing to stdout write_loop: Input/output error -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
