This tells you that your ESSID is 'Gandalf WajFaj', and the access point name is 10:05:......

|
|
```bash
|
|
nmcli radio
|
|
```
|
|
|
|
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.
|
|
|
|
```bash
|
|
nmcli wlan0 wifi rescan
|
|
```
|
|
|
|
```bash
|
|
nmcli device wifi list
|
|
```
|
|
|
|
Now to connect.
|
|
|
|
```bash
|
|
nmcli device wifi connect [SSID] [your password] [wifi password]
|
|
```
|
|
|
|
Alternatively, you can use
|
|
|
|
```bash
|
|
nmcli -ask device wifi connect [SSID]
|
|
```
|
|
|
|
And it'll ask for your password, so you're not typing it in in full view.
