    "No Wi-Fi Adapter Found" on ASUS X409FA-EK034T

    I am new to Ubuntu. I am running Ubuntu 18.04.3 from a live USB on my laptop (ASUS X409FA-EK034T). I wish to connect to the internet wirelessly. When I go to Settings > Wi-Fi I see the message


    No Wi-Fi Adapter Found
    Make sure you have a Wi-Fi adapter plugged in and turned on

    How can I connect to the internet by Wi-Fi?

    Hi, welcome to the fora.
    New hardware runs best with new software. Do you see any difference in a live boot of 19.10?

    I doubt that it matters. Your /home/username directory is just fine. To be certain that you are in that directory before you start, simply do:
    Code:
    cd
    I have git cloned to my desktop, home and also, when I am answering forum questions here and elsewhere, to a directory I created; namely, /home/chili/Desktop/Forum. It can be abbreviated as ~/Desktop/Forum.

    The dkms install process automagically takes care of placing needed files in /usr/src and /var/lib as needed. The starting place; /home or Desktop or Downloads, etc., doesn't change it.
