34 .Nd "Intel 3945ABG Wireless LAN IEEE 802.11 driver"
36 To compile this driver into the kernel,
37 place the following lines in your
38 kernel configuration file:
39 .Bd -ragged -offset indent
43 .Cd "device wlan_amrr"
47 Alternatively, to load the driver as a
48 module at boot time, place the following lines in
50 .Bd -literal -offset indent
57 In both cases, place the following line in
59 to load the firmware modules:
60 .Bd -literal -offset indent
66 driver is an experimental driver providing support for the
68 3945ABG Wireless network adapter
72 driver configures the adapter for BSS operation (aka infrastructure mode).
73 This mode requires the use of an access point.
75 For more information on configuring this device, see
78 This driver requires firmware to be loaded before it will work.
79 For the loaded firmware to work the license at
80 .Pa /usr/share/doc/legal/intel_wpi/LICENSE
81 must be agreed to and the following line be added to
84 .Dl "legal.intel_wpi.license_ack=1"
86 .Bl -tag -width ".Pa /usr/share/doc/legal/intel_wpi/LICENSE" -compact
87 .It Pa /usr/share/doc/legal/intel_wpi/LICENSE
92 Join an existing BSS network (i.e., connect to an access point):
94 .Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00"
96 Join a specific BSS network with network name
99 .Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net"
101 Join a specific BSS network with 40-bit WEP encryption:
102 .Bd -literal -offset indent
103 ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
104 wepmode on wepkey 0x1234567890 weptxkey 1
107 Join a specific BSS network with 104-bit WEP encryption:
108 .Bd -literal -offset indent
109 ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
110 wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
116 Verify that the necessary firmware modules are loaded and the
119 tunable has been set.
120 .It "wpi%d: could not load firmware"
121 An attempt to upload the firmware image to the onboard microcontroller failed.
122 This should not happen.
123 .It "wpi%d: fatal firmware error"
124 An unknown error has occurred in the uploaded firmware, you may have to
125 unload/reload the driver to continue.
126 .It "wpi%d: Radio transmitter is switched off"
127 The hardware switch controlling the radio is currently turned off.
128 Data transmission is not possible in this state.
130 Not all the error messages are documented here.
132 Automatic recovery of firmware failures is not currently supported, nor is
133 detection of toggling the radio switch on.
135 Background scanning is not currently supported.
