I don't use BT5 or Xiaopan just use unsecured networks with 7x64. I have had a ALFA NH, NHR, NHA and have a Kasens 9000 (RTL8187L) coming this week. I sold the NH to a friend but it was the best by far :yes . The NHR died in less than a year, nice ALFA quality. ........not. It was an OK card anyway. The NHA is a weak piece of junk with useless software ( . Hope the Kasens is the best yet.
