.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):
p 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 BUGS Not all the error messages are documented here.
p Background scanning is not currently supported. .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 .
