I can't establish wired Internet connection on my desktop pc. It tries to connect to "wired connection 1" and even if, after minutes, it finally (not always) manages to "connect"(according to the network indicator icon on panel) , I have no Internet.. Does any solution exist?

I tried to find a solution in older posts with no luck. I have this issue since lubuntu 15.10. Recently i have installed the new version of lubuntu 16.04 which i currently use, but so far No difference. The pc is dual boot and in the other OS everything works fine. So i assume it is not a hardware issue. I'm not exactly too familiar with linux. Thanks a lot!
