I installed Ubuntu 14.04.30 LTS using a USB stick. I didn't dual boot my pc, I deleted my old OS. I can't find Enable Wireless in the network menu. The output for rfkill

I am new to Linux and have no idea what to do. I can see the WiFi symbol at the top right corner of the screen. But its blank. When I click on it I can see that Enable Networking is checked. The other options are Edit connections & VPN connections. I don't have access to internet. Can't use Ethernet as a WiFi network is all I can access. I have just downloaded Ubuntu 14.04.3 and haven't installed any drivers or packages
lspci -knn | grep Net -A2
terminal command.
