5.0 out of 5 starsD-Link DWA-556 Extreme "N" Network Adapter Works Fantastic!
By Wavey Davey on July 26, 2009
Verified Purchase
I don't have much to write about this great product except to say that it works 110% to the good, has no obvious faults or problems, achieves close to 300Mb/s speed without tweaking, fiddling around, or special configuration, and overall is not to be feared as a PCI-Express network adapter. I was using its PCI equivalent, the DWA-552 "N" Adapter for almost 2 months with similar success, and was forced to start using the PCI-Express variety because I started using twin EVGA GTX-285 video cards in the PC, and lost the PCI slot in the process. This is an install it, and forget it system, and works 100% seamlessly with any Vista 64-bit system. I've never booted the computer and not had wifi-it just simply works every time, without fail, no questions asked!

There's a green activity light on the back of the device that blinks off, and on whenever the signal is being accessed, which is 100% of the time, so it's blinking a lot but it's not annoying at all. The three "antenna" that stick out the back of the unit are flexible and can point up at a 45-degree angle to acquire the signal better. The adapter is small, only weighs a few grams, certainly less than 4-ounces or so, and takes up very little space in the PCI cavity of the computer, a plus.

I just used the drivers off the original CD ROM, never even bothered with the D-Link web site and the "latest drivers" which I guess should be done at some point, but I'm having zero problems with the adapter so I've been reluctant to test fate and change a thing at this point.

That's about it for my review of this product. It works, it's simple to work with, install, there is no maintenance or trickery needed to get it functioning 100% with a Vista 64-bit system, so I recommend it highly and give it my 5-Stars Seal of Approval: ***** !

5.0 out of 5 starsEasy installation and it works.
By E. Collins on September 12, 2008
I recently bought a desktop computer without a wireless card thinking I was going to wire it directly to the router. When it arrived I decided to install the computer in a separate room from the router and therefore needed to use a wireless adapter. I had a Belkin USB adapter already and tried to install it on the new computer with Vista Home Premium 64. After several frustrating hours and multiple driver downloads and visits to online forums I still could not get the adapter to recognize my network. I then decided to go with an internal wireless card. Since my computer only has PCI express slots available this seemed to be my only choice. I ordered it Thursday morning (payed up for overnight shipping) and it arrived the following day. I opened the computer, installed the card in < 5 minutes. I booted up the computer and Vista asked me for a driver. I downloaded the latest driver from D-link site to my flash drive. Inserted the flash drive in my computer, added my MAC address to my router, entered my security password AND I WAS ON THE INTERNET. Not only that but the speed seems excellent. I cannot express how happy I am with a product that works as advertised and was so easy to install. Thank you D-Link!!!!

5.0 out of 5 starsWorks exactly like it should
By R. Schuler on August 19, 2008

I use it with the D-link DIR-655 router (another product I wholeheartedly recommend) and it works perfectly. I can stream video with a reliable wireless connection that doesn't constantly peter out like those other manufacturers. Plus I don't have to worry about more adapters clogging up my desktop. Always on, always fast, and great range; what more could you want out of your wireless adapter?

3.0 out of 5 starsD-Link Needs to Work on Their Software
By Fellow Traveler on June 20, 2008
I have a D-Link 655 Xtreme N router, and it has worked very well. I decided to purchase an Xtreme N PCI-E network adapter (D-Link DWA 556) to make the most of the speeds these units were supposed to be capable of together. I purchased the DWA 556 through Amazon and had my son bring it to me in Thailand, as he was about to visit. I also purchased a D-Link DWA 130 Xtreme N USB network adapter. The DWA 130 has worked very well, for the most part. The DWA 556 has been another story.

To make a long story short, I had multiple problems installing the card and getting it to work. Some of these had to do with the bios, as my motherboard is about a year and a half old and it had issues with getting the pci-express slot to work. I (my son actually) was able to get the card to work after using a very good bios update utility from Asus. However, upon returning from a trip of a few days, the software for the card seemed to be acting up. It appeared at times to have difficulty making a secure connection with the router after entering the password, though I have Windows XP and this was apparently a known issue only with Windows 2000. If I disabled the card through windows, windows was unable to enable it. If I tried to open the connection manager, often the window would not open at all, so no adjustments could be made.

Inspired by the fact that the card had worked well for a brief period, I went ahead and updated the driver from the D-Link website. The updating process was not smooth at all. At times the update would hang up part way, but then still act as if it was installed later. When I tried again later, the installation went through, but terminated with a sign that told me there was no card to be found on the machine.Read more ›
