39 .Nd Broadcom BCM430x/4318 IEEE 802.11b/g wireless network driver
43 driver provides support for Broadcom BCM430x/4318 wireless network adapters.
44 For more information on configuring this device, see
47 The following per-interface variables are implemented in the
52 .Bl -tag -width ".Va txpwr_calib"
56 Channel dwell time during scan (msec).
60 Number of ticks before LED enters idle state.
64 Enable software TX power calibration.
67 The following cards are among those supported by the
71 .Bl -column -compact "Apple AirPort Extreme" "BCM4318" "Mini PCI" "b/g" -offset 6n
72 .It Em "Card Chip Bus Standard"
73 .It Buffalo WLI-PCI-G54S BCM4306 PCI b/g
74 .It Dell Wireless 1370 BCM4318 Mini PCI b/g
75 .It Dell Wireless 1470 BCM4318 Mini PCI b/g
76 .It Dell Truemobile 1400 BCM4309 Mini PCI b/g
77 .It Dell Latitude D505 BCM4306 PCI b/g
78 .It Apple AirPort Extreme b/g
81 The firmware for the adapter is not shipped with
83 and must be obtained separately.
84 An archive with firmware files that are known to work can be found at:
85 .Bd -literal -offset indent
86 http://leaf.dragonflybsd.org/~sephe/bwi/v3.tbz
89 The firmware files conventionally reside in
90 .Pa /libdata/firmware/bwi
91 and will be loaded when the interface is brought up.
93 the v3 subdirectory in the above firmware archive should exist
94 in the firmware folder.
95 The full list of paths checked for firmware can be found in the
110 driver first appeared in
116 driver was written by
122 .An Taylor R. Campbell Aq campbell@mumble.net .
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.
132 driver does not yet support cardbus devices.
