You get an overview of your radio devices. You're told that eth0 deals with your ethernet and wlan0 deals with wifi. wlan0 is a file which represents your wifi device.

|
Now to connect.
|
|
|
|
> nmcli device wifi connect [SSID] [your password] [wifi password]
|
|
|

Alternatively, you can use
|
|
|
|
> nmcli -ask device wifi connect [SSID]

|
And it'll ask for your password, so you're not typing it in in full view.
