I have a good gaming pc, HD7950, FX8320...etc. Now I dont use terminal at all for the most part so please guide me in simple language!

My problem: No internet connection. Cant access the net. The strange thing is that if I manually setup LAN ip, DNS then ubuntu connects immediately or so it displays, but no connection in reality. If I set to automatic DHCP then it forever loops in searching for connection but fails each time.

I ran ifconfig but that did not show any "eth0/1" device, instead only "lo" and "ens3p0" or something.

I think I am supposed to manually add the interface but that is demanding more priviliges. Please help me. I am a linux noob for the most part. Use it for basic computing only.
 
Solution
Ubuntu 16.04 changed the network interfaces name to that more strange ones.

in particular it is Ubuntu switching to systemd that handles the new predictable device naming.

lo is localhost (loopback interface... 127.0.0.1...)
ens3p0 should be your ethernet lan (assuming that you do not have wireless).
Try setting all to automatic DHCP, and then try running "sudo dhclient".
