NAME    [Toc]    [Back]

     wlan -- generic 802.11 link-layer support

SYNOPSIS    [Toc]    [Back]

     device wlan

DESCRIPTION    [Toc]    [Back]

     The wlan device provides generic code to support 802.11 drivers, including
 host AP mode.	Currently it is required for the wi(4), an(4) and
     ath(4) drivers but will eventually be required by all 802.11 drivers.

     If the associated interface is marked for debugging with, for example,

	   ifconfig wi0 debug

     then messages describing the operation of the 802.11 protocol will be
     sent to the console.  With the interface marked for debugging, doing:

	   sysctl debug.ieee80211=1

     causes additional messages to be generated.  Many drivers will also display
 the contents of each 802.11 frame sent and received when the interface
 is marked with both debugging and ``link2''; e.g.

	   ifconfig wi0 debug link2

     Beware however that some management frames may be processed entirely
     within the device and not be received by the host.

COMPATIBILITY    [Toc]    [Back]

     The module name of wlan was used to be compatible with NetBSD.

SEE ALSO    [Toc]    [Back]

STANDARDS    [Toc]    [Back]

HISTORY    [Toc]    [Back]

     The wlan driver first appeared in FreeBSD 5.0.
