WLAN(4)                FreeBSD Kernel Interfaces Manual                WLAN(4)

NAME
     wlan - generic 802.11 link-layer support

SYNOPSIS
     device wlan

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

SEE ALSO
     an(4), ath(4), awi(4), netintro(4), wi(4)

STANDARDS
     More information can be found in the IEEE 802.11 Standard.

HISTORY
     The wlan driver first appeared in FreeBSD 5.0.

AUTHORS

     was adapted to FreeBSD by Sam Leffler.  This manual page was written by
