I have been looking at several websites to try and set up wifi on Ubuntu with no success. OK, this website talks about the post 18.04 way. But how do you set it up after that version? I saw this website as well, and it talks about some of the differences but I still haven’t been successful yet. I am getting that “No adapter found” message. I am using a Century Link router, model number C1000A. It is not connected directly to the computer. I would be grateful to any and all who could render any kind of assistance, thank you.
