The line
Dec 31 14:54:59 linux-ioxs NetworkManager: <info>  (wlan0): deactivating 
device (reason: 2).
is not an error. That just says the device is now deactivated and the reason 
code 2 - means "Device is now managed".
You can check device states and reason codes in 
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/include/NetworkManager.h

In the logs you should see entry like this:
NetworkManager[1287]: <info> WiFi enabled by radio killswitch; enabled by 
state file

Verify rfkill state with:
rfkill list

Check NM states with:
nmcli nm

What are the versions of NetworkManager daemon and the applet?
