Open a terminal with Ctrl+Alt+t and type the following commands:

rfkill unblock wifi
nmcli nm wifi on

It should re enable the Wifi interface.

Before rebooting, try the following command to see if it's not hardware blocked: rfkill list wifi – Sylvain Pineau Apr 03 '14 at 20:45
nothing returns from that – dinesh707 Apr 03 '14 at 20:45
