Those reviewers who went in to detail did talk about having the unit close to the router and/or trying other units in the same position with no problems and/or mentioned the quality of the connection in terms of the speed. Not all did that. Some did all those things. It seemed to be enough different people, some of whom did go in to some detail to make me suppose that there really is a problem with B&W's implementation of airplay. Of course, the only way to know is to have one in your own setting. Oh, and they also mentioned different routers, some Apple, some not.
