NAME

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

SYNOPSIS

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

           device iwi
           device iwifw
           device pci
           device wlan
           device firmware

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

           if_iwi_load="YES"

     In both cases, place the following line in loader.conf(5) to acknowledge the firmware
     license (see below):

           legal.intel_iwi.license_ack=1

DESCRIPTION

     The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG MiniPCI and 2225BG PCI
     network adapters.  iwi supports station, adhoc, and monitor mode operation.  Only one
     virtual interface may be configured at any time.  For more information on configuring this
     device, see ifconfig(8).

     This driver requires the firmware built with the iwifw module to work.  For the loaded
     firmware to be enabled for use the license at /usr/share/doc/legal/intel_iwi.LICENSE must be
     agreed by adding the following line to loader.conf(5):

           legal.intel_iwi.license_ack=1

FILES

EXAMPLES

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

           ifconfig wlan create wlandev iwi0 inet 192.168.0.20 \
               netmask 0xffffff00

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

           ifconfig wlan create wlandev iwi0 ssid my_net up

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

           ifconfig wlan create wlandev iwi0 ssid my_net \
                   wepmode on wepkey 0x1234567890 weptxkey 1 up

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

           ifconfig wlan create wlandev iwi0 wlanmode adhoc 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 crashed 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 the iwifw(4) firmware module is installed 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.
