.. _wifi:
Wi-Fi
=====
*Availability: Linux*
.. image:: ../_static/wifi.png
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.
