Summary: I'm a technology professional, and I had some trouble getting the included software to work right. I had to move back and forth between the Windows (Vista) utilities and the D-Link utility, and finally gave up and just used Windows to configure the card.
Summary: I just installed it yesterday, but so far I'm fully satisfied with it. Installation was easy and fast. Immediately, my network was found and I've been connected at 54mbps ever since. Quite honestly, my internet connection is stronger than when I have a wired connection to the router.
Summary: Bought the DLink after reviewing several options to turn my home computer's hard wired connection into wireless. Computer is less than 15' from the Linksys router, no walls in between, I get 100% signal (from the same location) on my Dell laptop, but only 35-50% on the computer with this card.
Summary: This thing just works. I have combined it with the D-link 2310 Rangebooster G router and get up to 108Mbps speed for the same money as other 54Mbps router/card combinations. Noticed a huge difference in download speeds over my wireless a/b combo. Excellent for my online games.
Summary: That's the time it took for my wife to get the mail to me writing this review. Popped off the cover, slipped in card, installed software, and bam. Running good old XP (32 bit) and the card works flawlessly. Got it for $11.50 here on amazon. Very impressed.
Summary: Similar to a previous review, initially my WDA-2320 was hogging 10-30% of my CPU cycles with deferred procedure calls (DPCs) and hardware interrupts. After removing a sound card that shared the same IRQ, the problem remained.
Summary: Strongly recommended for users of Windows Vista both 32-bit and 64-bit. This is one of the few wireless cards that will work out-of-the-box. I had to replace a Netgear card due to flaky Vista drivers especially for the 64-bit version.
