Wireless cannot be enabled

I successfully managed wireless network connection on my thinkpad by manual method (iwconfig+dhcpcd).
But when I switched to the automatic management - NetworkManager + network-manager-applet, only wired connection is working.Pressing the manage wireless key (fn9) on my laptop didnot link up wlan0 and  the tray icon of network shows the "wireless is disabled" message always.

The dmesg result after pressing Fn9 is as below,

[17838.210267] iwlwifi 0000:08:00.0: L1 Enabled; Disabling L0S
[17838.275786] ADDRCONF(NETDEV_UP): wlan0: link is not ready
