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

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

138.Sh DIAGNOSTICS
139.Bl -diag
140.It "iwm%d: device timeout"
141The driver will reset the hardware.
142This should not happen.
143.It "iwm%d: firmware error"
144The onboard microcontroller crashed for some reason.
145The driver will reset the hardware.
146This should not happen.
147.It "iwm%d: timeout waiting for firmware initialization to complete"
148The onboard microcontroller failed to initialize in time.
149This should not happen.
150.It "iwm%d: could not load firmware image '%s'"
