.Dt IPW 4
.Sh NAME
.Nm ipw
.Nd "Intel PRO/Wireless 2100 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 ipw"
.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_ipw_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
ipw_bss_load="YES"
ipw_ibss_load="YES"
ipw_monitor_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for the
.Tn Intel
PRO/Wireless 2100 MiniPCI 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_ipw/LICENSE
must be agreed to and the following line be added to
.Xr loader.conf 5 :
.Pp
.Dl "legal.intel_ipw.license_ack=1"
.Sh FILES
.Bl -tag -width ".Pa /usr/share/doc/legal/intel_ipw/LICENSE" -compact
.It Pa /usr/share/doc/legal/intel_ipw/LICENSE
.Nm
firmware license
.El
.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Pp
.Dl "ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00"
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "ifconfig ipw0 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 ipw0 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 ipw0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "ipw%d: device timeout"
The driver will reset the hardware.
This should not happen.
.It "ipw%d: firmware error"
The onboard microcontroller crashes for some reason.
The driver will reset the hardware.
This should not happen.
.It "ipw%d: timeout waiting for firmware initialization to complete"
The onboard microcontroller failed to initialize in time.
This should not happen.
.It "ipw%d: could not load firmware image '%s'"
The driver failed to load the firmware image using the
.Xr firmware 9
subsystem.
Verify that the necessary firmware modules are loaded and the
license agreement
.Xr loader 8
tunable has been set.
.It "ipw%d: could not load microcode"
An attempt to upload the microcode image to the onboard microcontroller failed.
This should not happen.
.It "ipw%d: could not load firmware"
An attempt to upload the firmware image to the onboard microcontroller failed.
This should not happen.
