.Sh NAME
|
|
.Nm iwn
|
|
.Nd "Intel Wireless WiFi Link 4965AGN IEEE 802.11n 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 iwnfw"
|
|
.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 line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_iwn_load="YES"
|
|
.Ed
|
|
.Pp
|
|
In both cases, place the following line in
|
|
.Xr loader.conf 5
|
|
to acknowledge the firmware license (see below):
|
|
.Bd -literal -offset indent
|
|
legal.intel_iwn.license_ack=1
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for
|
|
.Tn Intel
|
|
Wireless WiFi Link 4965AGN PCI-Express network adapters.
|
|
.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.
|
|
For the loaded firmware to be enabled for use the license at
|
|
.Pa /usr/share/doc/legal/intel_iwn/LICENSE
|
|
must be agreed by adding the following line to
|
|
.Xr loader.conf 5 :
|
|
.Pp
|
|
.Dl "legal.intel_iwn.license_ack=1"
|
|
.Sh FILES

.Sh EXAMPLES
|
|
Join an existing BSS network (i.e., connect to an access point):
|
|
.Pp
|
|
.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

.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 installed and the license agreement
|
|
.Xr loader 8
|
|
tunable has been set.
|
|
.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.
