Management Frames

I know everything that the driver is "supposed" to work under, but if 
someone can recommend particular hardware (preferrably brand and exact 
model number, not just chipset) and firmware on which they've tested a 
number of hostap's features, I'd be interested. I'd like to isolate any 
problems I'm having with stability as well as management frame issues 
from issues with my particular hardware, and am able to aquire other 
hardware if necicary.

Any help would be appreciated, thanks in advance
