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. I built my PC and use Win 7 on it so I was counting on it to have the needed drivers or at least find them. It didn't seem to work at first but with a little patience and after a few seconds I was able to sync / connect to my wireless network with no problems.
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 won't work right. Otherwise, allow XP to manage the card. Comes with a stubby little device that wants to be an antenna when it grows up.
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. This is how our got broken. Be aware that you will need to put the antenna on top of your CPU, check if you have enough space there.
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. The software that goes with it is good too.
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. It's currently picking up five bars of WiFi from a router on a different floor in my house. Highly recommended.
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. I wanted to stream radio music in my basement as I can't pick anything up with a regular radio.
