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 iwn100fw"
50.Cd "device iwn105fw"
51.Cd "device iwn135fw"
52.Cd "device iwn2000fw"
53.Cd "device iwn2030fw"
54.Cd "device iwn4965fw"
55.Cd "device iwn5000fw"
56.Cd "device iwn5150fw"
57.Cd "device iwn6000fw"
58.Cd "device iwn6000g2afw"
59.Cd "device iwn6000g2bfw"
60.Cd "device iwn6050fw"
61.Ed
62.Pp
63Or you can use
64.Bd -ragged -offset indent
65.Cd "device iwnfw"
66.Ed
67.Pp
68to include them all.
69.Pp
70Alternatively, to load the driver as a
71module at boot time, place the following lines in
72.Xr loader.conf 5 :
73.Bd -literal -offset indent
74if_iwn_load="YES"
75iwn1000fw_load="YES"
76iwn100fw_load="YES"
77iwn105fw_load="YES"

139    netmask 0xffffff00
140.Ed
141.Pp
142Join a specific BSS network with network name
143.Dq Li my_net :
144.Pp
145.Dl "ifconfig wlan create wlandev iwn0 ssid my_net up"
146.Pp
147Join a specific BSS network with 64-bit WEP encryption:

158.Sh DIAGNOSTICS
159.Bl -diag
160.It "iwn%d: device timeout"
161The driver will reset the hardware.
162This should not happen.
163.It "iwn%d: firmware error"
164The onboard microcontroller crashed for some reason.
165The driver will reset the hardware.
166This should not happen.
167.It "iwn%d: timeout waiting for firmware initialization to complete"
168The onboard microcontroller failed to initialize in time.
169This should not happen.
