NAME

     iwi - Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device iwi
           device pci
           device wlan
           device firmware

     Alternatively, to load the driver as a module at boot time, place the
     following lines in loader.conf(5):

           if_iwi_load="YES"
           wlan_load="YES"
           firmware_load="YES"

     In both cases, place the following lines in loader.conf(5) to load the
     firmware modules:

           iwi_bss_load="YES"
           iwi_ibss_load="YES"
           iwi_monitor_load="YES"

DESCRIPTION

     The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG
     MiniPCI and 2225BG PCI network adapters.

     By default, the iwi driver configures the adapter for BSS operation (aka
     infrastructure mode).  This mode requires the use of an access point.

     For more information on configuring this device, see ifconfig(8).

     This driver requires firmware to be loaded before it will work.  For the
     loaded firmware to work the license at
     /usr/share/doc/legal/intel_iwi/LICENSE must be agreed to and the
     following line be added to loader.conf(5):

           legal.intel_iwi.license_ack=1

FILES

     /usr/share/doc/legal/intel_iwi/LICENSE  iwi firmware license

EXAMPLES

     Join an existing BSS network (i.e., connect to an access point):

           ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00

     Join a specific BSS network with network name “my_net”:

           ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

     Join a specific BSS network with 64-bit WEP encryption:

           ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
               wepmode on wepkey 0x1234567890 weptxkey 1

     Join a specific BSS network with 128-bit WEP encryption:

           ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
               wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

     iwi%d: device timeout  The driver will reset the hardware.  This should
     not happen.

     iwi%d: firmware error  The onboard microcontroller crashes for some
     reason.  The driver will reset the hardware.  This should not happen.

     iwi%d: timeout waiting for firmware initialization to complete  The
     onboard microcontroller failed to initialize in time.  This should not
     happen.

     iwi%d: could not load firmware image%s’  The driver failed to load the
     firmware image using the firmware(9) subsystem.  Verify that the
     necessary firmware modules are loaded and the license agreement loader(8)
     tunable has been set.

     iwi%d: could not load boot firmware  An attempt to upload the boot
     firmware image to the onboard microcontroller failed.  This should not
     happen.

     iwi%d: could not load microcode  An attempt to upload the microcode image
     to the onboard microcontroller failed.  This should not happen.

     iwi%d: could not load main firmware  An attempt to upload the main
     firmware image to the onboard microcontroller failed.  This should not
     happen.
