Enable WiFi on Ubuntu 12.04 Lenovo Thinkpad E440

If the wifi interface is in soft blocked state, you could try a sudo rfkill unblock all or sudo rfkill unblock .

I have Lenovo Thinkpad E440. Just now I installed Ubuntu 12.04 LTS.

Problem is Wifi is not enabled on this Ubuntu, only wired internet is enabled.

So please help me how to enable Wifi on this version of Ubuntu?

Following is the ouput of lshw -c network. Please somebody help me.
