The D-Link DWA-556 is a draft 802.11n wireless client designed for delivering high-quality wireless performance for at-home use. A step up from the DWA-552, the DWA-556 is a PCI-Express card versus just PCI, thereby allowing it to deliver information even faster. Like its peer, the DWA-556 outputs up to 14x faster and 6x farther than a typical 802.11g network, while still maintaining backwards compatibility  In addition, the DWA-556 boasts three external antennas for enhanced reception, WPA/WPA2 encryption for improved security, and the ability to stream HD media when connected to an Xtreme N Gigabit Router (DIR-655 or DIR-660). Unlike its more fashionable cousin (the dual-band DWA-160), the DWA-556 adds along Yahoo Widgets Desktop Tools, while still maintaining its peers ability for Internet phone calling with VoIP. The D-Link DWA-556 retails for $89.99 and comes with a 1 year limited warranty.

This seemed to work OK under Linux, though I didn't test it extensively.

I tried for months to get it to behave under Windoze XP SP3, without success. I have an unknown source of interference in my environment which I have not yet been able to track down. With my other equipment, it is only a minor annoyance, but it renders this card, under XP, nearly unusable. Sometimes it will maintain the connection for minutes at a time, but that is the exception. Signal is very weak, and thruput is low. For comparison, my old (MSI) 802.11g PCI card in the very next slot of the same computer gets an excellent signal, has about 4x the thruput, and seldom (briefly) drops the connection.

Twice I tried to get the latest drivers to work in my machine, and each time it took me hours to back them out so that Windoze would boot.

The manager program doesn't remember the key, so my family had to re-enter it after every boot.

The support people did try to help, but they are saddled with an incredibly bad online case reporting program. They can send me emails, but I can only respond through their system, and that is so bad I couldn't figure out how to update my own case.
