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: ***** !

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!!!!

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?

I have had a DIR-655 D-Link wireless router for some time now, and just installed this DWA-556 into a new PC that I built. Works like it should - no setup problems at all. Running Windows 7 Ultimate 64-bit on a Gigabyte GA-P55A-UD4P mobo, Core i5-750 2.66ghz overclocked to 3.40ghz, 8 GB DDR3 SDRAM PC3 12800. What more can I say - it works like it should!

If you need a PCIe card that can act as a 802.11n access point, this is your card. Literally, this is the only card you can buy as far as I can tell. Everyone else wants to sell you a separate AP.

I have an Intel Core i3 server with Asus motherboard, one PCIe 1x slot (the little tiny ones) and I wanted to get rid of my separate wireless access point. This did the trick. But it's not easy.

You need to set up hostapd. You need to set up dhcdp. You need to set up your firewall rules and your QoS. If you're comfortable with that, then believe me - it works, and I am very happy with how much faster than 802.11g it is. It's an ath9k chipset which has usable support built into linux kernels from 2.6.30 and up.

I have my iPad, Android phone, Xbox 360, PS3, Wii all using this as their access point with WPA2. Works great - but took a couple hours to configure. But if you're using linux you're used to that.

I bought this for a standalone Ubuntu box and, given the reputation Linux has for being driver-challenged (think it would be fairer to say that hardware manufacturers don't support Linux well enough), was concerned the DWA-556 wouldn't work at all or would require a lot of driver fiddling.

I was extremely pleased that I installed it, booted up and machine, and presto! the wireless connection came up immediately.

Am very pleased with the product and would definitely recommend it.

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. A final installation seemed to be successful, but I was then unable to boot my machine at all. It would get to the Windows screen, then shut down and restart repeatedly. I first removed the card, but this did not help. Finally I booted in safe mode and removed all of the software for the DWA 556. At that point everything returned to normal.

When I called tech support, they said that my mistake was to have purchased the card in the US and then to have used it on a machine purchased in Thailand. They said my having taken the card out of the country also voided the warranty, so I am left with a loss of about $80.

I am not fully persuaded by the argument that the source of the problems was my using the card in a different region. Some of the problems I experienced were also mentioned in reviews of a similar card (D-Link 552) within the US with a US-made machine. An example would be the fact that at certain points when using the D-Link connection manager, the load on the CPU would be really high (in my case making for a whine from the computer that was very hard to tolerate or work with). Furthermore, some of these problems, like getting the connection manager to open up, also occurred with an older D-Link wireless G network adapter that I had purchased in Thailand.

Since I am not an expert in these matters, I cannot thoroughly assess the idea about using parts in a different region. I feel I have to give D-Link the benefit of the doubt there. I do want to say this, however. Why don't the makers of these products spend more time on developing decent software? If you read online reviews of supposedly high-end network adapters (D-Link as well as others), you wouldn't really want to buy ANY of them. Often the problems appear to be in the software. To summarize my own experience, my D-Link software was unable to work fluidly with two different adapters from D-Link (one a card and one as USB backup). The connection manager for the DWA 556 overloaded the CPU. Often I could not get the connection manager to open up at all. Finally, I had problems several times getting through the password stage on a secure connection (with a very good D-Link router).

I would like to urge big companies like D-Link to ease up on the breakneck race to make new products available at an ever faster pace, and instead start offering software that is fully tested, reliable, and easy to work with. This would save many earnest computer users hours of figuring and trying things out, when their technicians and developers should be doing that work in advance.

I give this product a three because I think it probably can work well given the right conditions, but I feel the software is really poor.

Contrary to the conflicting information from D-Link and others, this DWA-556 PCIe wireless adapter DOES WORK IN WINDOWS 7!!!! Just DO NOT INSTALL the D-Link drivers from the disk. Turn off the computer, insert the card, turn on the computer, AND LET WINDOWS 7 DO THE REST.

And it's FAST >>>>>>>>>>>>>

My Windows 7 Ultimate x64 installation detected this card without me needing to install any drivers. Paired with a D-Link DIR-825 router, the network and sharing center reports my connection speed usually at 300Mbps, occasionally 130Mbps. I have an external antenna attached and am about 20 feet through one floor and some ductwork away from the router.

Installed with Windows Vista 32 Business SP1
Immediately recognized, best connection ever.
Do not use D_Link driver, just make sure you are connected to Internet via LAN and the OS will automatically choose the driver.
