I've been all through the trak and in some places it looks like this  
card is working for some but the details are sketchy at best and many  
still post that it is not working and the confusion from cross- 
reference contamination makes it hard to follow or figure out.

I have 3 machines with these cards in them and the lack of working  
wifi in Ubuntu is the only reason the machines remain turned off and  
unused.

There is also speculated rumors that by changing the product ID to  
0x13 it allows the card to work as if it were the AR5212a rather than  
the AR2412a.

Regardless, the cards don't work with madwifi and ath_info doesn't  
allow you to make any changes so rebranding as a possible temporary  
solution can't be examined.

Yes I realize ndis wrapper works but I prefer a native solution.

Also, the aBit AirPace and now the D-Link DWA556 are not the only  
PCIe cards available, I came across a card (actually I bought two)  
made by Han Hoi Precision Industries LTD that supports 802.11a/b/g/n,  
confirmed working in XP, Vista, Mac OSX (natively at 300mpbs) and  
Ubuntu using ndis wrapper method and based on AR5218 (I believe).
