30.Os
31.Sh NAME
32.Nm iwm
33.Nd Intel IEEE 802.11ac 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 iwm"
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 iwm3160fw"
49.Cd "device iwm3168fw"
50.Cd "device iwm7260fw"
51.Cd "device iwm7265fw"
52.Cd "device iwm7265Dfw"
53.Cd "device iwm8000Cfw"
54.Cd "device iwm8265fw"
55.Cd "device iwm9000fw"
56.Cd "device iwm9260fw"
57.Ed
58.Pp
59Or you can use
60.Bd -ragged -offset indent
61.Cd "device iwmfw"
62.Ed
63.Pp
64to include them all.
65.Pp
66Alternatively, to load the driver as a
67module at boot time, place the following lines in
68.Xr loader.conf 5 :
69.Bd -literal -offset indent
70if_iwm_load="YES"
71iwm3160fw_load="YES"
72iwm3168fw_load="YES"
73iwm7260fw_load="YES"
74iwm7265fw_load="YES"

98.El
99.Pp
100.Nm
101supports
102.Cm station
103mode operation.
104Only one virtual interface may be configured at any time.
105For more information on configuring this device, see
106.Xr ifconfig 8 .
107.Pp
108This driver requires the firmware built with the
109.Nm iwmfw
110module to work.
111.Pp
112Currently,
113.Nm
114only supports 802.11b and 802.11g modes.
115It will not associate to access points that are configured to operate only
116in 802.11n or 802.11ac modes.
117.Sh EXAMPLES
118Join an existing BSS network (i.e., connect to an access point):
119.Bd -literal -offset indent
120ifconfig wlan create wlandev iwm0 inet 192.168.0.20 \e
121    netmask 0xffffff00
122.Ed
123.Pp
124Join a specific BSS network with network name
125.Dq Li my_net :
126.Pp
127.Dl "ifconfig wlan create wlandev iwm0 ssid my_net up"
128.Pp
129Join a specific BSS network with 64-bit WEP encryption:
130.Bd -literal -offset indent
131ifconfig wlan create wlandev iwm0 ssid my_net \e
132	wepmode on wepkey 0x1234567890 weptxkey 1 up
133.Ed
134.Pp
135Join a specific BSS network with 128-bit WEP encryption:
136.Bd -literal -offset indent
137ifconfig wlan create wlandev iwm0 wlanmode adhoc ssid my_net \e
138    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

140.Sh DIAGNOSTICS
141.Bl -diag
142.It "iwm%d: device timeout"
143The driver will reset the hardware.
144This should not happen.
145.It "iwm%d: firmware error"
146The onboard microcontroller crashed for some reason.
147The driver will reset the hardware.
148This should not happen.
149.It "iwm%d: timeout waiting for firmware initialization to complete"
150The onboard microcontroller failed to initialize in time.
151This should not happen.
152.It "iwm%d: could not load firmware image '%s'"
153The driver failed to load the firmware image using the
154.Xr firmware 9
155subsystem.
156Verify the
157.Xr iwmfw 4
158firmware module is present.
159.It "iwm%d: could not load boot firmware"
160An attempt to upload the boot firmware image to the onboard microcontroller
161failed.
162This should not happen.
163.It "iwm%d: could not load microcode"
164An attempt to upload the microcode image to the onboard microcontroller failed.
