I don't have an answer to your question, just a suggestion.  What speed
do you actually get when you test it?  If the real life speed rather
than the reported speed is different, then it is time to investigate
why.  If there is a real life discrepancy, then it could be that the
firmware in linux is reverse engineered versus the custom tuned
firmware for windows written by the manufacturer.

Not sure if this will work for you, but there should be one you can use
somewhere on the web.
