I have dual booted Windows 8.1 and Ubuntu 15.04 on Asus xx130d laptop. I have wired internet connection. The problem I'm facing is I am not able to access internet on Ubuntu though I can access it on Windows.

I have read many posts about it but none of them helped me, I had tried Kubuntu 15.04 and Ubuntu 14.04 without installing it and in both OS net didn't connect. When I had freshly installed Ubuntu, net was accessible but while installing updates from Ubuntu Software Centre it was taking too much time, so I just disconnected it and tried to reconnect it but it didn't connect.

ifconfig:
