31.Sh NAME
32.Nm iwn
33.Nd Intel IEEE 802.11n wireless network driver
34.Sh SYNOPSIS
35To compile this driver into the kernel,
36include the following lines in your
37kernel configuration file:
38.Bd -ragged -offset indent
39.Cd "device iwn"
40.Cd "device pci"
41.Cd "device wlan"
42.Cd "device firmware"
43.Ed
44.Pp
45You also need to select a firmware for your device.
46Choose one from:
47.Bd -ragged -offset indent
48.Cd "device iwn1000fw"
49.Cd "device iwn2000fw"
50.Cd "device iwn2030fw"
51.Cd "device iwn4965fw"
52.Cd "device iwn5000fw"
53.Cd "device iwn5150fw"
54.Cd "device iwn6000fw"
55.Cd "device iwn6000g2afw"
56.Cd "device iwn6000g2bfw"
57.Cd "device iwn6050fw"
58.Ed
59.Pp
60Or you can use
61.Bd -ragged -offset indent
62.Cd "device iwnfw"
63.Ed
64.Pp
65to include them all.
66.Pp
67Alternatively, to load the driver as a
68module at boot time, place the following lines in
69.Xr loader.conf 5 :
70.Bd -literal -offset indent
71if_iwn_load="YES"
72iwn1000fw_load="YES"
73iwn2000fw_load="YES"
74iwn2030fw_load="YES"
75iwn4965fw_load="YES"
76iwn5000fw_load="YES"
77iwn5150fw_load="YES"

128.Sh EXAMPLES
129Join an existing BSS network (i.e., connect to an access point):
130.Bd -literal -offset indent
131ifconfig wlan create wlandev iwn0 inet 192.168.0.20 \e
132    netmask 0xffffff00
133.Ed
134.Pp
135Join a specific BSS network with network name
136.Dq Li my_net :
137.Pp
138.Dl "ifconfig wlan create wlandev iwn0 ssid my_net up"
139.Pp
140Join a specific BSS network with 64-bit WEP encryption:
141.Bd -literal -offset indent
142ifconfig wlan create wlandev iwn0 ssid my_net \e
143	wepmode on wepkey 0x1234567890 weptxkey 1 up

151.Sh DIAGNOSTICS
152.Bl -diag
153.It "iwn%d: device timeout"
154The driver will reset the hardware.
155This should not happen.
156.It "iwn%d: firmware error"
157The onboard microcontroller crashed for some reason.
158The driver will reset the hardware.
159This should not happen.
160.It "iwn%d: timeout waiting for firmware initialization to complete"
161The onboard microcontroller failed to initialize in time.
162This should not happen.
163.It "iwn%d: could not load firmware image '%s'"
