I installed this unit on a brand new Dell machine. After having problems with the BSOD on shutdown, I downloaded the new drivers and the old drivers -nothing helped. I called Dell support (I didn't even want to call Netgear) and they thought the Blue Screens were coming from a bad motherboard. Dell sent out a technician to replace it. They ran some diagnostics and they came to the same conclusion. It was the wireless card. Like others have said, don't be cheap~ get the Linksys card instead.
