I took a chance on this because it was so cheap and I am not a USB fan when it comes to networking. I got it for my HTPC and it blew me away on how good it does. I have it 25ft away from my router and it is a straight shot with no obstetrical. If your using this with Win 7 use the windows default drivers.
This is a N upgrade of the one I have but I don't know what setup your using this in so.
