Also, it's shown as if succesfully installed, but the wireless continue as before.
I'm a newbie programming, I just migrated from Windows because I feel better with Ubuntu, I can follow instructions and run commands, but I have no idea about the results the terminal is showing me when it comes to an error.
Thanks for any help
Wifi not working, wl module doesn't exist
