I have a Broadcom 43225 802.11 b/g/n wireless card on my HP laptop and am having trouble getting airmon-ng to work with it. I mean I run airmon-ng and the wireless card is not detected, any ideas?

I checked out Linux wireless LAN support http://linux-wless.passys.nl to see if my card is supported and the closest thing I could find was this:
