wpi - Intel 3945ABG Wireless LAN IEEE 802.11 driver


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.conf5:



The driver provides support for the Intel 3945ABG Wireless network adapter 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).
