Summary: First, make sure you get the newest drivers from the RealTek website (NOT the Netgear website--they won't work on XP). It is the RTL8169 driver and it is located under PCI devices on the website After installing the RealTek drivers and removing the Netgear drivers, the card started working fine and much better than the internal card on my old laptop.
Summary: For anyone with a laptop without a built-in LAN adapter, this is a good solution. After downloading and installing new drivers from the Netgear website, this unit worked flawlessly and as expected right out of the box.
Summary: This card works very well. I purchased the card for two reasons: 1) faster internet access than the wireless adapter I have and 2) to enable faster movement of files from the laptop to my home server using Gig-E. My laptop is running WinXP and the card installed without any problems. One of the easiest installs I have ever done.
Summary: I am shocked that Netgear is providing an old driver (2004) NOT CERTIFIED WITH XP. Bought this Jan 2006. The crashing drove me crazy since nothing identified the driver as the problem until a day later through process of elimination. Wow. Netgear really blew it on this one.
