There is way too little information in your post.

What is the version of hostapd?  If that's the program that gives you 
the problem, its version number is highly relevant.  The main point of 
releasing new versions is to resolve users' problems!

What is the version of the kernel?  The kernel works with the card and 
talks to hostapd.

What is the revision of the card?  Some cards even have different 
chipsets in different revisions.

What driver do you use?  Is it ath9k or madwifi or something else?

What is "unresponsive"?  What do you do with it, what kind of response 
do you expect and what do you actually observe?  Is there anything 
interesting in the kernel log?

It's hard to give an intelligent response to your question without 
having all that information.

I used to have two DWA-552 cards.  One have the antennas wide apart 
(http://www.computerdirectcorp.com/cdproductcatalog/images/products/DWA552.jpg) 
and it didn't work on some motherboards.  Another had the antennas close 
to each other (http://www.compupoint.ca/images/DWA-552.jpg) and worked 
on the systems where the first one didn't work.  That's a totally 
anecdotal observation, and may be irrelevant to your issue.
