WiFi
====
Configure WiFi using ``nmcli``:

* List all available networking devices:

.. code:: bash

    nmcli -t device

.. code:: bash

    usb0:ethernet:connected:usbncm
    wlan0:wifi:disconnected:
    eth0:ethernet:unavailable:
    docker0:bridge:unmanaged:
    can0:can:unmanaged:
    can1:can:unmanaged:
    sit0:iptunnel:unmanaged:
    lo:loopback:unmanaged:

* List all available Wi-Fi networks by SSID:

.. code:: bash

    nmcli dev wifi list

.. code:: bash

* Connect to your Wi-Fi (and enter password on prompt):

.. code:: bash

    nmcli --ask dev wifi connect network-ssid

If you have forgotten the IP assigned to your Arduino Portenta X8 or your DHCP server has assigned a new IP as the previous lease has been expired you can always scan for open SSH ports using nmap.

.. code:: bash

    nmap -sV 192.168.8.0/24 -p 22 -open
