 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"
 85.Sh FILES

 91.Sh EXAMPLES
 92Join an existing BSS network (i.e., connect to an access point):
 93.Bd -literal -offset indent
 94ifconfig wlan create wlandev iwi0 inet 192.168.0.20 \e
 95    netmask 0xffffff00
 96.Ed
 97.Pp
 98Join a specific BSS network with network name
 99.Dq Li my_net :
100.Pp
101.Dl "ifconfig wlan create wlandev iwi0 ssid my_net up"
102.Pp
103Join a specific BSS network with 64-bit WEP encryption:
104.Bd -literal -offset indent
105ifconfig wlan create wlandev iwi0 ssid my_net \e
106	wepmode on wepkey 0x1234567890 weptxkey 1 up
107.Ed
108.Pp
109Join a specific BSS network with 128-bit WEP encryption:
110.Bd -literal -offset indent
111ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \e
112    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

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