i tried enabling wifi using hotkey (fn-f3) no success. here's syslog when try it:

code:

jun 19 16:47:20 pond networkmanager[890]: <info> wifi enabled radio killswitch  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): bringing device.  jun 19 16:47:20 pond kernel: [ 1809.158370] addrconf(netdev_up): wlan0: link not ready  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): supplicant interface state:  starting -> ready  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): device state change: 2 -> 3 (reason 42)  jun 19 16:47:20 pond networkmanager[890]: <info> wifi disabled radio killswitch  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): device state change: 3 -> 2 (reason 0)  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): deactivating device (reason: 0).  jun 19 16:47:20 pond networkmanager[890]: <info> policy set 'auto eth0' (eth0) default ipv4 routing , dns.  jun 19 16:47:20 pond networkmanager[890]: <info> policy set 'auto eth0' (eth0) default ipv4 routing , dns.  jun 19 16:47:20 pond networkmanager[890]: <info> (wlan0): taking down device.
