If you need wifi and a static IP I can recommend this approach from the debian wki using wpa_supplicant.
If you need a more dynamic approach but still want or have to use the command line, there is a command line tool for network manager called nmcli. It is not very intuitive. I also had the problem that my Laptop has an internal wifi card and I had to configure a connection for an additional wifi usb dongle. Below the next headline are some useful commands I used to add a new connection and bring it up.
While writing this post I discovered some additional useful links I put at the end of this post.
Short summary of useful nmcli commands.¶
List status of available network interfaces:
nmcli device status
List wifi access-points:
nmcli device wifi list
Add a new connection named “foobar-home” for the network interface with the ifname wlx2824ff1a0227 and the ssid “foo”:
nmcli con add con-name foobar-home ifname wlx2824ff1a0227 type wifi ssid foo
Now we have to modify foobar-home to use wpa-psk:
nmcli con modify foobar-home wifi-sec.key-mgmt wpa-psk
Then we set the password “barbaz”:
nmcli con modify foobar-home wifi-sec.psk barbaz
Finally we bring the connection up: nmcli con up foobar-home
