To all the good folks here flaming me:
Where to begin.. The silent majority. I'm hearing statistics like "<.01% failure" and I'm not buying it. The very fact that the card in sold as "AC" does not even have a menu that supports AC or even N is a red flag right there. The gating issue however is failure to maintain a connection. Let's examine that:
The fact that the issues exist on various current OSes (x86 as well as x64 flavors) is another red flag. The issues exist across the gamut of laptop manufacturers as well as ages (8 yr old laptops right up to current models some of which actually shipped with this card installed) is yet another slam dunk. The only variable left is RF environment. Granted, I don't have a spectrum analyzer handy, however other manufacturers cards running inches away on other devices have no such issues. So NOTO BE A "JERK" or ruffle anyone's feathers (gato negro) - as us annoying customers that buy your goods tend to do, but maybe you can explain where that <.01% failure data comes from? Is it empirical data??, or is there some magic calculation? I'm seeing and endless string of posters here reiterating the same connection issues. And I'm guessing the vast majority of posters are not even aware of this forum or are looking elsewhere for answers if not to return the card.
