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 connec-
tivity are reported. The events currently reported are changing one of
the following setting :
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 :
New Access Point/Cell address
The interface has joined a new Access Point or Ad-Hoc Cell, or
lost its association with it. This is the same address that is
reported by iwconfig.
Scan request completed
A scanning request has been completed, results of the scan are
available (see iwlist).
Tx packet dropped
A packet directed at this address has been dropped because the
interface believes this node doesn't answer anymore (usually
maximum of MAC level retry exceeded). This is usually an early
indication that the node may have left the cell or gone out of
range, but it may be due to fading or excessive contention.
Custom driver event
Event specific to the driver. Please check the driver documenta-
The interface has successfully registered a new wireless
client/peer. Will be generated mostly when the interface acts as
of them, the exact list depends on the specific hardware/driver combi-
nation. Please refer to driver documentation for details on when they
are generated, and use iwlist(8) to check what the driver supports.
