Question

Answer 1

It's because you need to tell netplan to use NetworkManager. You will have to add a line to the configuration file of netplan. So edit the /etc/netplan/ 00-...-wifi.yaml file with sudo privileges.

Find the flowing lines:

network:
  version: 2

and add the line:

renderer: NetworkManager

so it will now be like this:

network:
  version: 2
  renderer: NetworkManager

Now, to activate the new line, you can type in the terminal either:

sudo netplan apply

which will apply the new line, or:

sudo netplan try

which will only try to apply for a few minutes, and reverts back automatically, if you don't approve it.

The Wi-Fi should start showing up, immediately.
