Recently I've switched fully to Ubuntu after having a huge fuss with Windows. Even though I'd used Ubuntu before, my knowledge about Ubuntu and Linux in general is still very much to be desired. So please excuse any dumb mistakes or questions. Previously I had used Ubuntu 17.10, and when I updated to 18.04, I began to have trouble with my internet connection. It's wired Ethernet, and I've followed a ton of other tutorials and am still having trouble. Here is some info that should pertain to the topic at hand, and if there is anything else you need just ask and I'll update the post.
