See Chapter 20 of the FreeBSD handbook, especially §20.2.

The problem is that a lot of wireless manufacturers have the habit of
changing wireless chipsets without changing model numbers. So a revision
X might work while revision Y won't.

Try and look at the card. Sometimes the chipset is visible and you can
look for it in the manual pages. But often it is enclosed in a metal cover.

In my experience, asking shop clerks which chipset a card uses only
produces puzzled looks.

Second best thing is to download the driver for the revision of the card
that you want to buy. Unpack the driver and read the .inf files. That
will probably yield the chipset type. If not, use strings(1) on the
drivers themselves.
