Your card is a
BCM4321
This card is not directly supported on FreeBSD at the moment.
You can use
if_ndis(4) and use the Windows driver on FreeBSD, using Google, there seem to be some people using the BCM4321 with
if_ndis(4) successfully. It's not "plug-and-play", but with some effort you should be able to get it working.
The FreeBSD handbook has a section on configuring cards with NDIS:
