Is there any way to connect to a specific WiFi SSID using the terminal?
The GUI way is not working for me so I need some way to do it by way of the
command line (through PuTTY).

On this system there seems not to be any wpa_supplicant.conf file to enter the
WiFi data into...
I have the same problem on another PC running Ubuntu Mint 20.04...

I need to redirect their Internet networking to WiFi during the time of the
fiber outage so I do not lose too much processing work. I.e. making them
dual-homed.

I *am* a member of the netdev group:

$ groups bosse
bosse : bosse adm cdrom sudo dip plugdev netdev lpadmin sambashare
