29.Sh NAME
30.Nm iwn
31.Nd Intel IEEE 802.11n wireless network driver
32.Sh SYNOPSIS
33To compile this driver into the kernel,
34include the following lines in your
35kernel configuration file:
36.Bd -ragged -offset indent
37.Cd "device iwn"
38.Cd "device pci"
39.Cd "device wlan"
40.Cd "device firmware"
41.Ed
42.Pp
43You also need to select a firmware for your device.
44Choose one from:
45.Bd -ragged -offset indent
46.Cd "device iwn1000fw"
47.Cd "device iwn100fw"
48.Cd "device iwn105fw"
49.Cd "device iwn135fw"
50.Cd "device iwn2000fw"
51.Cd "device iwn2030fw"
52.Cd "device iwn4965fw"
53.Cd "device iwn5000fw"
54.Cd "device iwn5150fw"
55.Cd "device iwn6000fw"
56.Cd "device iwn6000g2afw"
57.Cd "device iwn6000g2bfw"
58.Cd "device iwn6050fw"
59.Ed
60.Pp
61Or you can use
62.Bd -ragged -offset indent
63.Cd "device iwnfw"
64.Ed
65.Pp
66to include them all.
67.Pp
68Alternatively, to load the driver as a
69module at boot time, place the following lines in
70.Xr loader.conf 5 :
71.Bd -literal -offset indent
72if_iwn_load="YES"
73iwn1000fw_load="YES"
74iwn100fw_load="YES"
75iwn105fw_load="YES"

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

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