hi tortuga, if you are considering to buy this one, I would suggest you AWUS036H.
I have it both, AWUS036H is still the best choice, but no N support.
I have the same problem obelix99 has, but I use AWUS036NHR only for inject (when I need more power) and AWUS036H for dump.
I will try latest compat-wireless asap (...too busy these days) and let you know
