List of Plugins


The MadWifi plugin collects information about Atheros wireless LAN chipsets from the MadWifi driver. It uses the /sys filesystem to identify cards handled by this driver automatically but can be configured manually, too. Because very many statistics are available, an advanced selection mechanism is provided.
