D-Link DWL-G520 Wireless PCI Adapter, 802.11g, 108Mbps Review

Average Reviews:

(More customer reviews)Usually you should discount reviews complaining about problems with a computer add-on: they say more about the reviewer and their systems, perhaps, then they do about the product you are trying to evaluate. I think, though, that some aspects of my experience might be generalizable, maybe even applicable to your situation.
I have been a satisfied user of D-Link wireless products for over three years now. I upgraded to the 802.11g products (WAP and PCI cards) a year ago to a run a network of up to five computers, usually three Win XP or Win 2000 workstations and two notebooks. As I look around my office, though, I see boxes full of failed or problematic routers, WAPs, and cards. It seems, although I have only just realized the extent of it, that these D-Link products all fail with remarkable regularity. In the past, I have just routinely replaced them: that's how much I have liked their ease of use and their performance.
Well, that's over with my latest purchase: the DWL-G520 adapter (my second). It taught me two disturbing things about D-Link wireless. First, the adapter can really screw up your system. This one's driver (regardless of the update version) consumes 90+ percent of a very high-powered CPU. (Windows XP Home, all the latest updates, etc.) It has brought an essential machine to its knees by hugely slowing down everything it does. Disabling the adapter (which solves the problem, at the price of disconnecting me from the world) brings on the fabled Blue Screen of Death. The second disturbing thing is that D-Link support simply has not responded to e-mail messages, period. Their Web site lies when it promises 36 hour response. I can cope--I have a strong background in computing and can devise temporary workarounds--but I shudder to think how uncomfortable this behavior would make most people feel.
Those are the proverbial three strikes: consistently short times to failure, occurrence of really bad driver behavior, and hopelessly bad support. My relationship with D-Link is over; I will have to try some other vendor's offering. If you don't mind the risk of having a similar experience, and think you can cope with absolutely no support, then by all means consider this product. I hope and trust, though, that you (and I) can do better with a different vendor.
