31.Sh NAME
32.Nm iwi
33.Nd "Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 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 iwi"
40.Cd "device iwifw"
41.Cd "device pci"
42.Cd "device wlan"
43.Cd "device firmware"
44.Ed
45.Pp
46Alternatively, to load the driver as a
47module at boot time, place the following line in
48.Xr loader.conf 5 :
49.Bd -literal -offset indent
50if_iwi_load="YES"
51.Ed
52.Pp
53In both cases, place the following line in
54.Xr loader.conf 5
55to acknowledge the firmware license (see below):
56.Bd -literal -offset indent
57legal.intel_iwi.license_ack=1
58.Ed
59.Sh DESCRIPTION
60The
61.Nm
62driver provides support for
63.Tn Intel
64PRO/Wireless 2200BG/2915ABG MiniPCI and 2225BG PCI network adapters.
65.Nm
66supports
67.Cm station ,
68.Cm adhoc ,
69and
70.Cm monitor
71mode operation.
72Only one virtual interface may be configured at any time.
73For more information on configuring this device, see
74.Xr ifconfig 8 .
75.Pp
76This driver requires the firmware built with the
77.Nm iwifw
78module to work.
79For the loaded firmware to be enabled for use the license at
80.Pa /usr/share/doc/legal/intel_iwi/LICENSE
81must be agreed by adding the following line to
82.Xr loader.conf 5 :
83.Pp
84.Dl "legal.intel_iwi.license_ack=1"

98.Pp
99Join a specific BSS network with network name
100.Dq Li my_net :
101.Pp
102.Dl "ifconfig wlan create wlandev iwi0 ssid my_net up"
103.Pp
104Join a specific BSS network with 64-bit WEP encryption:
105.Bd -literal -offset indent
106ifconfig wlan create wlandev iwi0 ssid my_net \e
107	wepmode on wepkey 0x1234567890 weptxkey 1 up
108.Ed
109.Pp
110Join a specific BSS network with 128-bit WEP encryption:
111.Bd -literal -offset indent
112ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \e
113    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

115.Sh DIAGNOSTICS
116.Bl -diag
117.It "iwi%d: device timeout"
118The driver will reset the hardware.
119This should not happen.
120.It "iwi%d: firmware error"
121The onboard microcontroller crashed for some reason.
122The driver will reset the hardware.
123This should not happen.
124.It "iwi%d: timeout waiting for firmware initialization to complete"
125The onboard microcontroller failed to initialize in time.
126This should not happen.
127.It "iwi%d: could not load firmware image '%s'"
128The driver failed to load the firmware image using the
129.Xr firmware 9
130subsystem.
131Verify the
132.Xr iwifw 4
133firmware module is installed and the license agreement
134.Xr loader 8
135tunable has been set.
136.It "iwi%d: could not load boot firmware"
137An attempt to upload the boot firmware image to the onboard microcontroller
138failed.
139This should not happen.
140.It "iwi%d: could not load microcode"
141An attempt to upload the microcode image to the onboard microcontroller failed.
142This should not happen.
143.It "iwi%d: could not load main firmware"
144An attempt to upload the main firmware image to the onboard microcontroller
145failed.
146This should not happen.
