Blitzz Wireless BWI715

Just a fair warning, folks... After exhaustive research on this PCI card, I have found it to be faulty. I have three of them, and all three are causing problems. I have tried to find updated drivers, and although there are atheros drivers out there that may work to solve the issue, I cannot find them for download. The BWI does not seem to cause problems on slower PCs, such as the old 500 I use for a firewall, and a 366 I built for a jukebox in my livingroom. But, on the 1.4, the 2.8 and the 3G PCs, the card has caused problems. I'm not sure if XP is culprit, because I have it on the 500. Just a heads up.
