Query: Drops connection

This USB adapter is wasting of money and time. Originally I wanted to upgrade my 11.b adapter to 11.g adapter, so i bought this one. It turned out a bad bad decision, the speed fluctuated so wildly, and drops connection several time an hour. And the distance betwen the adpter to the router is only 6 feet downstairs.
