will this work with pfsense 2.2

The chipset is AR9580 so yes.
What i find strange with this card, is that the chipset is a/b/g/b, but this card itself doesn't allow 5GHz operation?
It seems they use the dualband chip, but have the card in 2 different variants: http://i.mt.lv/routerboard/files/R11-140818123104.pdf
Also the 9580 is a 3 chain design, but this card has only 2 chains ???If you look at their FCC conformity declaration there is this little sentence at the end:
http://i.mt.lv/routerboard/files/187UC14_GRANT-140805123230.pdfWhen operating in the 802.11n, 40 MHz mode, the operating frequency band is limited to 2422 to 2452 MHz.
This is usually a sign of insufficient RF design because they can't fulfill the requirements of the needed filters on the edge channels.
Where would you want to run this card?
Almost everywhere on the world the legally allowed txpower on this band is 100mW / 20dBm.
This card "could" send considerably more, but you're probably not allowed to. -
i want to put it in my APU system board
-
I meant where in the world.
In an APU you will have problems to close the case because the heat sink is too high.
Also this card is consuming 7W when transmitting a lot.
I'm not sure if the APU PCIe slot can provide that much power.
If it can make sure your PSU can provide enough. -
Yes i have both the 2.4 verision and the 5 ghz version working. I have been slacking on benchmarking as someone requested that and i have not done it yet. It was the best performing card i have. Even better than 3x MIMO ATH extreme cards.
I am using them in an undisclosed location!!! Mounted on Advantech PCM-9362
Can't vouch for the power to your APU slot though…
http://routerboard.com/R11e-5HnDAnd yes i would say that there may be height issues on some builds. I also doubt their power claims. I saw some numbers from a signal analyzer(Amazon reviewer) and wonder what its really putting out. There may be something going-on in regards to their RouterOS and card firmware. Its all closed source so we will never know…

2x2 vs 3x3 always depends heavily on your RF environment.
If you have the right environment 3x3 will outperform 2x2.
In the wrong environment you will get the same or less.
Mostly because the rate controller is trying to achieve the higher rates, which it can't, and thus wastes time it could spend on transferring useful traffic.Regarding advertised performance values and real performance values. The card is able to perform at the advertised values… On one frequency exactly in the middle of the spectrum of their RF filter design.
Move away from these optimal design points and the performance will decrease drastically.
If you don't know what to look for in the datasheets you won't notice these flaws.
If i can't find any indication of these limitations in a datasheet, the specific cards are a nogo for me.
For consumer market devices this hardly is a problem, but in industrial wireless applications it makes a difference.Depending on the regulatory configuration of the OS the card is working on, the driver does also lots of stuff limiting your output power.
This is to ensure you don't violate the regulatory definitions give by ETSI/FCCI/JP. -
Here is the post i was referencing earlier. Thought it was an Amazon review but i was wrong.

mmm… thanks for everyones help
dont want to order it and find out my psu isnt adequate or it doesnt fit ie height wise in my apu 1d case
how does it compare to the compex wle200nx?
im guessing these cards are all 2x2 mimo
thanks

My recommendation would be an Apple Airport Extreme card. They can be had for cheap used off ebay.
Good card with 3x3
https://wikidevi.com/wiki/Atheros_AR5BXB112Older but supports some virtual platforms
https://wikidevi.com/wiki/Apple_AR5BXB72This card performed similarly to the Mikrotik with only 400mw.
http://www.amazon.com/Ubiquiti-SR71-E-PC-Express-802-11a-400mW/dp/B004GIGOL6
Costs more but low profile and regular u.fl connectors-good for upgrades in laptops.
