I bought a Dell XPS laptop from them for over 8,000. z . It breaks the WIFI connection. The gentleman of technical support dell reported that "the C disk format and reinstalling the windows should help". I chose to say that the Chinese KILLER card they put in has this feature that does not work properly. Dell, however, reported that the hardweru does not mention. So much in the subject.
