.Sh NAME
.Nm iwn
.Nd Intel IEEE 802.11n wireless network driver
.Sh SYNOPSIS
To compile this driver into the kernel,
include the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device iwn"
.Cd "device pci"
.Cd "device wlan"
.Cd "device firmware"
.Ed
.Pp
You also need to select a firmware for your device.
Choose one from:
.Bd -ragged -offset indent
.Cd "device iwn4965fw"
.Cd "device iwn1000fw"
.Cd "device iwn5000fw"
.Cd "device iwn5150fw"
.Cd "device iwn6000fw"
.Cd "device iwn6000g2afw"
.Cd "device iwn6000g2bfw"
.Cd "device iwn6050fw"
.Ed
.Pp
Or you can use
.Bd -ragged -offset indent
.Cd "device iwnfw"
.Ed
.Pp
to include them all.
.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_iwn_load="YES"
iwn4965fw_load="YES"
iwn1000fw_load="YES"
iwn5000fw_load="YES"
iwn5150fw_load="YES"
iwn6000fw_load="YES"
iwn6000g2afw_load="YES"
iwn6000g2bfw_load="YES"
iwn6050fw_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Intel Centrino Advanced-N 6200
.It Intel Centrino Advanced-N 6205
.It Intel Centrino Advanced-N 6230
.It Intel Centrino Advanced-N + WiMAX 6250
.It Intel Centrino Ultimate-N 6300
.It Intel Centrino Wireless-N 130
.It Intel Centrino Wireless-N 1000
.It Intel Centrino Wireless-N 1030
.It Intel Centrino Wireless-N + WiMAX 6150
.It Intel Ultimate N WiFi Link 5300
.It Intel Wireless WiFi Link 4965
.It Intel WiFi Link 5100
.It Intel WiMAX/WiFi Link 5150
.It Intel WiMAX/WiFi Link 5350
.El
.Pp
.Nm
supports
.Cm station ,
.Cm adhoc ,
and
.Cm monitor
mode operation.
Only one virtual interface may be configured at any time.
For more information on configuring this device, see
.Xr ifconfig 8 .
.Pp
This driver requires the firmware built with the
.Nm iwnfw
module to work.
.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Bd -literal -offset indent
ifconfig wlan create wlandev iwn0 inet 192.168.0.20 \e
    netmask 0xffffff00
.Ed
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "ifconfig wlan create wlandev iwn0 ssid my_net up"
.Pp
Join a specific BSS network with 64-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wlan create wlandev iwn0 ssid my_net \e
	wepmode on wepkey 0x1234567890 weptxkey 1 up
.Ed
.Pp
Join a specific BSS network with 128-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net \e
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "iwn%d: device timeout"
The driver will reset the hardware.
This should not happen.
.It "iwn%d: firmware error"
The onboard microcontroller crashed for some reason.
The driver will reset the hardware.
This should not happen.
.It "iwn%d: timeout waiting for firmware initialization to complete"
The onboard microcontroller failed to initialize in time.
This should not happen.
.It "iwn%d: could not load firmware image '%s'"
The driver failed to load the firmware image using the
.Xr firmware 9
subsystem.
Verify the
.Xr iwnfw 4
firmware module is present.
.It "iwn%d: could not load boot firmware"
An attempt to upload the boot firmware image to the onboard microcontroller
failed.
This should not happen.
.It "iwn%d: could not load microcode"
An attempt to upload the microcode image to the onboard microcontroller failed.
This should not happen.
.It "iwn%d: could not load main firmware"
An attempt to upload the main firmware image to the onboard microcontroller
failed.
This should not happen.
