Add one for someone who is otherwise going to have to replace any Wifi card with one that supports 802.11a/b/g(/n) in host mode on FreeBSD (pfSense firewall), as well as works on Linux (Debian/Ubuntu) and Windows. Common ones are regrettably rare - so far I've been looking at two Atheros AR9280 based cards:
full length "high power" Ubiquiti SR-71e (http://www.wlanparts.com/product/SR71-E ... 400mW.html
half length Atheros based card with FreeBSD 8.1 drivers (something like the Sparklan WPEA-111N (http://www.sparklan.com/product.php?fun ... rod_id=157
These little PC's with either the GbE FACE module or the two Mini-PCIe FACE module and some wifi cards are ideal for replacing small office firewalls, routers, wifi access points, and VPN concentrators, many of which are FreeBSD based (m0n0wall, pfSense).
