No wi-fi icon/option in Ubuntu 14.04

Hi Friends, today(14/06/015) I was installed Ubuntu14.04, After installing every thing is normal(every Software is working fine), But after one day the wifi icon and option just disappeared. I have tried to reboot it and searching the settings for it, but it does not let me connect to a wifi connection in any way. The only way to connect to the internet is with a wired connection.

So, I try to fix this this a bug or something that has to do with the version? I installed it on a Lenovo G50-70 Model Laptop.

Here The Solution I found.

Please note that wireless was working fine all this time, its just the missing icon.

Here is what worked for me. Unity -> Startup Applications - and check "Indicator Application" (if its not already checked.) Next install following two packages: indicator-applet and indicator-network.

sudo apt-get install indicator-applet indicator-network

I am using Ubuntu 14.04 64bit on Lenovo G50-70 Model Laptop.
