Summary: I was a bit skeptical due to the fact that this didn't come with a CD for the needed drivers BUT on the other side of that idea we are talking about a NIC card that seemed to be standard fit / plug & play anyway.
Summary: I had problem with my old wireless Belkin card. This card replaced the old one and worked perfect, but... A problem was an antenna. It's only 2 feet long and if you have computer desk with a special place for the CPU tower it may be difficult to place the antenna in right position.
Summary: This unit installed easily on XP Pro. Works better than pretty much every other unit I've tried, including those made by the company whose parent name sounds like a cooking oil. If you have a non-broadcasting SSID, use the manufacturer-provided utility to manage the card, as the built-in XP client...
Summary: The wireless network card worked well even with the PC in the basement, and the router on the second floor. The external antenna is superior to built-in antennas. In addition, it cost only about half as much as more well known name brands wireless network cards.
Summary: I bought this adapter because my old one didn't work with Windows 7. Although it doesn't say it is "Windows 7 Ready" on the box, I got it up and running in about 5 minutes without Windows Update to help me. I installed the drivers included on the disk, and it worked like a charm.
Summary: My notebook and main PC are running Windows 7, but I have an old Dell in my basement that I use for old games that is running Windows Millenium which is based on Windows 98 code but works better with USB devices.
