38 .Nd Broadcom BCM430x/4318 IEEE 802.11b/g wireless network driver
40 To load the driver as a module at boot time, place the
42 .Pa /boot/loader.conf :
43 .Bd -literal -offset indent
49 driver provides support for Broadcom BCM430x/4318 wireless network adapters.
50 For more information on configuring this device, see
53 The following per-interface variables are implemented in the
58 .Bl -tag -width ".Va txpwr_calib"
62 Channel dwell time during scan (msec).
66 Number of ticks before LED enters idle state.
70 Enable software TX power calibration.
73 The following cards are among those supported by the
77 .Bl -column -compact "Buffalo WLI-PCI-G54S" "BCM4318" "CardBus" "b/g" -offset 6n
78 .Em "Card Chip Bus Standard"
79 Linksys WPC54Gv3 BCM4318 CardBus b/g
80 Linksys WPC54GSv2 BCM4318 CardBus b/g
81 Buffalo WLI-CB-G54S BCM4318 CardBus b/g
82 Buffalo WLI-PCI-G54S BCM4306 PCI b/g
83 Dell Wireless 1470 BCM4318 Mini PCI b/g
84 Dell Truemobile 1400 BCM4309 Mini PCI b/g
87 The firmware for the adapter is not shipped with
89 and must be obtained separately.
90 An archive with firmware files that are known to work can be found at:
91 .Bd -literal -offset indent
92 http://leaf.dragonflybsd.org/~sephe/bwi/v3.tbz
95 The firmware files have to reside in
97 and will be loaded when the interface is brought up.
115 driver first appeared in
121 driver was written by
122 .An Sepherosa Ziehau .
124 The hardware specification was reverse engineered by the people at
125 .Pa http://bcm-specs.sipsolutions.net .
126 Thanks go also to johill and mb on the #bcm-specs channel.
128 BCM4306 and BCM4309 chips do not work properly on channel 1, 2 and 3.
