iwevent - Display Wireless Events generated by drivers and setting changes
iwevent display Wireless Events received through the RTNetlink socket. Each line display
the specific Wireless Event which describe what has happened on the specified wireless
This command doesn't take any arguments.
There is two classes of Wireless Events.
The first class is events related to a change of wireless settings on the interface (typi-
cally 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 :
All those events will be generated on all wireless interfaces by the kernel wireless sub-
system (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 MAC address that is reported by iwconfig.
Scan request completed
A scanning request has been completed, results of the scan are available (see
Tx packet dropped
A packet directed at this address has been dropped because the interface believes
this node doesn't answer anymore. An early indication that the node may have left
the cell or gone out of range.
Custom driver event
Event specific to the driver. Please check the driver documentation.
The interface has successfully registered a new wireless client/peer. Will be gen-
erated mostly when the interface act as an Access Point (mode master).
The registration of the client/peer on this interface has expired. Will be gener-
ated mostly when the interface act as an Access Point (mode master).
Only some of those events will be generated on some wireless interfaces by the wireless
driver, and their support depend on the specific hardware/driver combination. Please refer
to driver documentation for details.
