iwevent displays Wireless Events received through the RTNetlink socket. Each line displays the specific Wireless Event which describes what has happened on the specified wireless interface. This command doesn't take any arguments.
There are two classes of Wireless Events.
The first class is events related to a change of wireless settings on the interface (typically done through iwconfig or a script calling iwconfig). Only settings that could result in a disruption of connectivity are reported. The events currently reported are changing one of the following setting : Network ID ESSID Frequency Mode Encryption All those events will be generated on all wireless interfaces by the kernel wireless subsystem (but only if the driver has been converted to the new driver API).
The second class of events are events generated by the hardware, when something happens or a task has been finished. Those events include :
Most wireless drivers generate only a subset of those events, not all of them, the exact list depends on the specific hardware/driver combination. Please refer to driver documentation for details on when they are generated, and use iwlist(8) to check what the driver supports.
