I bought a wifi dongle, and tried to get it to work in ubuntu 18.04 LTS. It came with a disk, realtek drivers. They didnt work, so I got some that do work, for some. I installed them, and now the system recognizes the driver, but when I blacklist the built-in wifi, the Realtek driver didn't connect to the internet. The message was that there was no wifi adapter.
Then I tried to install the driver for windows 10. This PC is an HP Pavilion windows 10 machine which has Ubuntu, and the Linux boot manager installed. Needless to say, the windows driver on the realtek drivers disk, didn't work, but one I found on the Internet works.
I've gone through several extensive debug sessions on this Web site but they seem to peter out with no indication as to wether a solution was found or everyone gave up.
What do you suggest?
I reran some informational commands that were in my terminal history.
The output follows...
