I've been using it for about a month now and it was really easy to setup in my old Dell Dimension (no wireless card). Installed the software, reboot and plugin the card and voila! there it was! Added the device to my network and started using the internet pretty quick. Good product. Thanks!

This was the second one of these cards I've purchased. It is sturdy and works great. The wireless network here restricted by MAC so when someone brings in a laptop for repair, I can just pop this card in and get to work without having to muck around trying to find their MAC address and get it allowed on the wireless network. 

Simple installation

This TrendNet card functions well, although a little slower than the Netgear one it replaced. The software was easy to install. My only sugggestion is not to use the "updated" software on the company's website but the included CD instead. Since I have a TrendNet router the hookup was clean. Connection speed is 11 megs, however, slower than the USB plug in version. Why, I do not know. Not an issue for me since my max speed is 7 megs.
