Summary: I bought this card thinking that I was buying a wireless network card, and I was wrong, ethernet cable only!!! when I made my search choices at Amazon, this came up as a wireless selection. I swear by Netgear, since I have had 1 of their routers in operation for almost 3 years running a wired and 2 wireless computers without a hitch, so actually the 3 star rating is for the mis-information at Amazon!
Summary: The box says "For Windows 7 updates visit [...]. But that web site doesn't have anything for the GA311. I searched online and found that some people were able to download Realtek drivers and get it to work. But that didn't work on Windows 7 either. After a couple of days, I gave up and returned the card. Maybe it could be made to work, but it isn't worth the hassle.
Summary: Purchased two Net Gear GA311 1g network cards. One came in DOA. Called support, and support said they could not help me. The card is "end of life, and therefore no support is available." No support in spite of Net Gear upgrading the drivers for Win7 recently. If Net Gear can't support their products I will never buy Net Gear again.
