Public bug reported:
When I disable the Wireless network (either using nm-applet's Enable
wireless option or nmcli nm wifi) and then enable it again, I expect the
WiFi network to be enabled again. Instead, NetworkManager believes it
has been disabled by the killswitch.
Steps to reproduce:
(1) The Wireless network is enabled and active
$ LC_ALL=C nmcli dev
DEVICE TYPE STATE
eth0 802-3-ethernet unavailable
wlan0 802-11-wireless connected
$ LC_ALL=C nmcli nm

running connected enabled enabled enabled

(2) Turn off the WiFi using nmcli (relevant syslog messages shown below)
$ nmcli nm wifi off
NetworkManager[8008]: <info> WiFi hardware radio set disabled
NetworkManager[8008]: <info> WiFi now disabled by radio killswitch
(3) Try turning on the WiFi using nmcli. No effect, no syslog messages. rfkill
even believes the hardware killswitch has been used.
$ nmcli nm wifi on

(4) Try restarting NetworkManager: it still believes the WiFi has been disabled
by the hardware killswitch.
$ sudo restart network-manager
network-manager start/running, process 9004
NetworkManager[9004]: <info> found WiFi radio killswitch rfkill1 (at

(driver (unknown))
NetworkManager[9004]: <info> WiFi disabled by radio killswitch; enabled by
state file
(5) Not even a system reboot solved the problem. Using rfkill is the only way
to restore the WiFi connectivity.
