This page documents the current state of the IWN driver for FreeBSD, the driver supports the Intel 4965AGN Wireless Card, often found in Intel Centrino based laptops. If your looking for the driver for the 3945 chipset check out the wpi page.

Note: A majorly updated version of the iwn driver has been committed to FreeBSD -Current (aka 8.0). This version is greatly advanced over the perforce version. If you intend to try the perforce version under 7.0 please make sure you are running 7.0-STABLE not 7.0-RELEASE

An up to date commentary on what I’m working on can often be found in my blog and this is a wiki page so you can check the page history for what has changed

Details on how to help debug the driver are in README file that’s in the download package.

For those of you wanting to try the perforce version of the driver, the script P4fetch.rb will help you easily obtain the files. The script was provided by Tom Evans.
