NAME

wpi -- Intel 3945ABG Wireless LAN IEEE 802.11 driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file: device wpi device wpifw device pci device wlan device wlan_amrr Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_wpi_load="YES"

DESCRIPTION

The wpi driver provides support for the Intel 3945ABG Wireless network adapter wpi supports station, adhoc, and monitor mode operation. Only one virtual interface may be configured at any time. For more informa- tion on configuring this device, see ifconfig(8). This driver requires the firmware built with the wpifw module to work.

EXAMPLES

Join an existing BSS network (i.e., connect to an access point): ifconfig wlan0 create wlandev wpi0 inet 192.168.0.20 \ netmask 0xffffff00 Join a specific BSS network with network name ``my_net'': ifconfig wlan0 create wlandev wpi0 ssid my_net up Join a specific BSS network with 64-bit WEP encryption: ifconfig wlan0 create wlandev wpi0 ssid my_net \ wepmode on wepkey 0x1234567890 weptxkey 1 up Join a specific BSS network with 128-bit WEP encryption: ifconfig wlan0 create wlandev wpi0 wlanmode adhoc ssid my_net \ wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

wpi%d: could not load firmware image '%s' The driver failed to load the firmware image using the firmware(9) subsystem. Verify the wpifw firmware module is installed. wpi%d: fatal firmware error An unknown error has occurred in the uploaded firmware, you may have to unload/reload the driver to continue. wpi%d: Radio transmitter is switched off The hardware switch controlling the radio is currently turned off. Data transmission is not possible in this state.
