Ubuntu Ethernet Connection cable unplugged

in flag

I have tried setting up my ethernet for a few weeks now without any progress. My wifi is working, but its too slow. I have already tried multiple cables and different routes. Would appreciate any help at this point.

I also for some reason have two ethernet interfaces, even though I only have one ethernet port on my laptop.

@David I added a screenshot of the network manager.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
