Here is what happens: systemd[1]: Started ifup for wlan0. wpa_supplicant[765]: Successfully initialized wpa_supplicant sh[737]: RTNETLINK answers: Device or resource busy sh[737]: Failed to bring up wlan0. systemd[1]: ifup@wlan0.service: Main process exited, code=exited, status=1/FAILURE wpa_supplicant[791]: nl80211: deinit ifname=wlan0 disabled_11b_rates=0 Furthermore, this kind of failure leaves a mess somehow, and subsequent attempts to connect lead to "RTNETLINK answers: File exists".
