.Sh NAME
|
|
.Nm wpi
|
|
.Nd "Intel 3945ABG Wireless LAN IEEE 802.11 driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device wpi"
|
|
.Cd "device pci"
|
|
.Cd "device wlan"
|
|
.Cd "device firmware"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following lines in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_wpi_load="YES"
|
|
wlan_load="YES"
|
|
firmware_load="YES"
|
|
.Ed
|
|
.Pp
|
|
In both cases, place the following lines in
|
|
.Xr loader.conf 5
|
|
to load the firmware modules:
|
|
.Bd -literal -offset indent
|
|
wpifw_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver is an experimental driver providing support for the
|
|
.Tn Intel
|
|
3945ABG Wireless network adapter
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the adapter for BSS operation (aka infrastructure mode).
|
|
This mode requires the use of an access point.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
This driver requires firmware to be loaded before it will work.
|
|
For the loaded firmware to work the license at
|
|
.Pa /usr/share/doc/legal/intel_wpi/LICENSE
|
|
must be agreed to and the following line be added to
|
|
.Xr loader.conf 5 :
|
|
.Pp
|
|
.Dl "legal.intel_wpi.license_ack=1"
|
|
.Sh FILES
|
|
.Bl -tag -width ".Pa /usr/share/doc/legal/intel_wpi/LICENSE" -compact
|
|
.It Pa /usr/share/doc/legal/intel_wpi/LICENSE
|
|

|
|
.Sh EXAMPLES
|
|
Join an existing BSS network (i.e., connect to an access point):
|
|
.Pp
|
|
.Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00"
|
|
.Pp
|
|
Join a specific BSS network with network name
|
|
.Dq Li my_net :
|
|
.Pp
|
|
.Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net"
|
|
.Pp
|
|
Join a specific BSS network with 40-bit WEP encryption:
|
|
.Bd -literal -offset indent
|
|
ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
|
|
wepmode on wepkey 0x1234567890 weptxkey 1
|
|
.Ed
|
|
.Pp
|
|
Join a specific BSS network with 104-bit WEP encryption:
|
|
.Bd -literal -offset indent
|
|
ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
|
|
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
|
|
.Ed
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.Xr firmware 9
|
|
subsystem.
|
|
Verify that the necessary firmware modules are loaded and the
|
|
license agreement
|
|
.Xr loader 8
|
|
tunable has been set.
|
|
.It "wpi%d: could not load firmware"
|
|
An attempt to upload the firmware image to the onboard microcontroller failed.
|
|
This should not happen.
|
|
.It "wpi%d: fatal firmware error"
|
|
An unknown error has occurred in the uploaded firmware, you may have to
|
|
unload/reload the driver to continue.
|
|
.It "wpi%d: Radio Transmitteer is switched off"
|
|
The hardware switch controlling the radio is currently turned off.
|
|
Data transmision is not possible in this state.
|
|
.Sh BUGS
|
|
Not all the error messages are documented here.
|
|
.Pp
|
|
Automatic recovery of firmware failures is not currently supported, nor is
|
|
detection of toggling the radio switch on.
|
|
.Pp
|
|
Background scanning is not currently supported
