.Dd October 5, 2008 .Dt WPI 4 .Os .Sh NAME .Nm wpi .Nd "Intel 3945ABG Wireless LAN IEEE 802.11 driver" .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device wpi" .Cd "device wpifw" .Cd "device pci" .Cd "device wlan" .Cd "device wlan_amrr" .Cd "device firmware" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent if_wpi_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the .Tn Intel 3945ABG Wireless network adapter. .Nm supports .Cm station , .Cm adhoc , and .Cm monitor mode operation. Only one virtual interface may be configured at any time. For more information on configuring this device, see .Xr ifconfig 8 .
p This driver requires the firmware built with the .Nm wpifw module to work. .Sh FILES l -tag -width ".Pa /usr/share/doc/legal/intel_wpi/LICENSE" -compact t Pa /usr/share/doc/legal/intel_wpi/LICENSE .Nm firmware license .El .Sh EXAMPLES Join an existing BSS network (i.e., connect to an access point): d -literal -offset indent ifconfig wlan0 create wlandev wpi0 inet 192.168.0.20 \e netmask 0xffffff00 .Ed
p Join a specific BSS network with network name .Dq Li my_net :
p .Dl "ifconfig wlan0 create wlandev wpi0 ssid my_net up"
p Join a specific BSS network with 64-bit WEP encryption: d -literal -offset indent ifconfig wlan0 create wlandev wpi0 ssid my_net \e wepmode on wepkey 0x1234567890 weptxkey 1 up .Ed
p Join a specific BSS network with 128-bit WEP encryption: d -literal -offset indent ifconfig wlan0 create wlandev wpi0 wlanmode adhoc ssid my_net \e wepmode on wepkey 0x01020304050607080910111213 weptxkey 1 .Ed .Sh DIAGNOSTICS l -diag t "wpi%d: could not load firmware image '%s'" The driver failed to load the firmware image using the .Xr firmware 9 subsystem. Verify the .Xr wpifw firmware module is installed. t "wpi%d: fatal firmware error" An unknown error has occurred in the uploaded firmware, you may have to unload/reload the driver to continue. t "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. .El .Sh SEE ALSO .Xr wpifw 4 , .Xr pci 4 , .Xr wlan 4 , .Xr wlan_ccmp 4 , .Xr wlan_tkip 4 , .Xr wlan_wep 4 , .Xr ifconfig 8 , .Xr wpa_supplicant 8 .Sh AUTHORS .An -nosplit The original .Nm driver was written for .Ox by .An Damien Bergamini Aq damien.bergamini@free.fr . .An Benjamin Close Aq benjsc@FreeBSD.org ported .Nm to .Fx . .Sh BUGS Not all the error messages are documented here.
