The card will receive an interrupt when you disable the rf kill switch
anyway whatever the wireless function is enabled or not. So the driver
will enable the wireless function again. Please check if the interface
(wlan0) is up when you disable the rf kill switch later. If it is not,
you have to bring it up manually (i.e. ifconfig wlan0 up) to enable the
wireless function. Otherwise please provide the dmesg with
debug=0x20000.

Thanks,
