Show your work, so your statements aren't misunderstood AND are accurate. I don't know what you mean by the 2nd phrase above. It isn't clear. Please. Make it easier to help you.

Ok, I think I've got to the root of the problem. For my internet to work, I have to set up PPPoE. (because of my ISP). But when I do:

Code:

sudo pppoeconf

Sorry, I scanned 1 interface, but the Access Concentrator of your provider did not respond. Please check your network and modem cables. Another reason for the scan failure may also be another running pppoe process which controls the modem.

So when I connect the ethernet cable (to any device) it just tries to connect and then it says "Disconnected Ethernet network".
Doing:

Code:

sudo dhclient enp2s0

also gives no output, and it doesn't seem to fix it.

ppp is normally handled by the router as a login to DSL networks. If you didn't have a router, then yes, you'd need something like that on 1 system and it would effectively have to be the router for your network.

Still waiting to see the new interfaces file.
A fresh sudo lshw -C network would be helpful too. The last one showed a very low connection speed, which usually means there is a cable problem.
