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: 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: 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.
