WiFI is connected to a network, but no WiFi icon is shown and no networks found!

[Sank_c]

So i just installed Kali Sana 2.0 and then ran apt-get dist-upgrade and after that the wifi icon at the top right just vanished and when i go to the drop down icon and search for networks it shows no network found even though it is connected to the network i used while installation but the wifi icon is gone and no networks are shown! I could not find any solution to the problem so if u guys could just help a newbie out, i would be very grateful!

Thank you
