Glances displays the Wi-Fi hotspot names and signal quality. If Glances
is ran as root, then all the available hotspots are displayed.

.. note::
    You need to install the ``wireless-tools`` package on your system.

In the configuration file, you can define signal quality thresholds:

- ``"Poor"`` quality is between -100 and -85dBm
- ``"Good"`` quality between -85 and -60dBm
- ``"Excellent"`` between -60 and -40dBm

It's also possible to disable the scan on a specific interface from the
configuration file (``[wifi]`` section). For example, if you want to
hide the loopback interface (lo) and all the virtual docker interfaces:

.. code-block:: ini

    [wifi]
    hide=lo,docker.*
    # Define SIGNAL thresholds in dBm (lower is better...)
    careful=-65
    warning=-75
    critical=-85

You can disable this plugin using the ``--disable-wifi`` option or by
hitting the ``W`` key from the user interface.
