After updating my Ubuntu to 15.04 my internet connection stops working randomly. It does not matter if it's connected through wifi or cable. It only stops working without saying it is not connected on the status bar. The applications cannot connect.

Try the command sudo apt-get remove network-manager*
This might work, since it removes the network manager. Also turn off the WiFi and unplug the network cable and plug it back ,try vice versa too. hope this will work.
