LarkBox with Ubuntu Server 20 cannot connect to internet via WiFi

I bought LarkBox Mini-Pc few weeks ago and I’m still struggaling to connect it to internet.
I installed Ubuntu Server latest release and even if I follow the instructions from this website

ls /sys/class/net
ls /etc/netplan/
sudoedit /etc/netplan/00-installer-config.yaml
sudo netplan apply
sudo netplan --debug generate
sudo netplan --debug apply

Please help me with this issue. It’s really annoing.

Thank you

Please, provide an “ls /etc/netplan” from your system.
