Summary: I bought a few of these because they perform well, even without the antenna connected. I had an HP computer that came with one of these from the factory. It's performance in that machine prompted me to buy more for the other three desktop computers that I have built myself.
Summary: I have had only marginal luck with wireless cards for desktops in the past. I use them at our church for remote offices where cables are hard to run or would not be asthetically appealing. This card gets excellent reception with great speeds. I will definitely buy another one when needed.
Summary: Not sure why there was a review that stated it would not work on their Windows 7, but I installed this into my motherboard, hooked everything back up, turned on the computer and it automatically installed all the required drivers and works great.
Summary: It seems like this card is hit or miss. I took a chance and have had nothing but problems getting it to connect using WPA2-Personal security. If I turn the security off, it connects just fine. Anything else it is very intermittent.
Summary: First of all, make sure you have a PCI express x1 slot available on your motherboard. (PCI express x1 slot is smaller than standard PCI slots) You should know how to line up the card with the motherboard.
