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 device firmware 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 information on configuring this device, see ifconfig(8). This driver requires the firmware built with the wpifw module to work. FILES
