Works if older drivers used (version 1.3)
Does not work with Win 7 64-bit using shipped software/drivers
If you've bought this product, and are getting crashes to desktop at startup (blue screen of death), the problem is the drivers.

Go to D-Link's official website and download the version 1.3 drivers. The automatic installation of the software may well fail as well, but as long as the driver is installed, you should connect on startup.

Note: if you have Windows update  set to automatic, make sure that it doesn't update  these drivers on you, after you get things working.

Strong Connection,
Fast Transfer,
Good distance,
Three antennas look badass
Non so far
Read a lot of reviews about not using the software, or the software causing problems. I forget why I installed mine but I have no problems whatever. If anything the most annoying part is having two wifi icons in the bottom right.

Used about 40ft from router through livingroom with just couches and chairs between.

Would highly recommend

Very easy installation and does what is needed.
None thus far.
This adapter was an upgrade from an old wireless G card. The difference is MASSIVE. Signals that I was getting normally at 0-20% strength are now coming in at 100%. I've yet to see my connections drop  at any time as is the stereotype of wireless. The N generation seems to a great improvement. :)

3 Antennas ? Look nice ?
Everything else, bad device.
I have 4 PC at home, 1 with a cheap tp-link G adapter, 2 with Rosewill cheap N adapter, and my main gaming system with this one (d-link extreme dwa-556). This extreme device range is really bad, the speed of it is slow as hell, It random disconnect, etc. I tried every d-link and atheros drivers possible and ... no changes. I thought it could be a slot problem on my gaming system but no, I tried it on 4 PC on a 2-3 weeks interval, performance is as bad on all PC.

The guaranteed is only 30 days at ncix, which is again, bad for a extreme device like this. You need to send it to D-Link for RMA after 30 days, but it cost almost the same as buying a new one in here. It's totally useless to RMA this to D-Link.

I seriously don't recommend this product, it was my worst adapter on my LAN Network. I removed this device completely from my system and it's now in the original box, throw in a big box where I keep all my old stuff not used anymore.

Sorry for my bad English, My native language is french.

-Strong, consistent signal
-Faster start-up connection than my old adapter
I have been interested in purchasing this adapter ever since it came out because of excellent reviews; however, the price was too high. A price drop  over last year has made this a very sensible purchase. I am very pleased with the performance and the strength of the signal. I also noticed that it seems to connect to the internet faster when my computer logs on to Windows. I am currently using this adapter with the Netgear WNR3500L router and have had no compatibility issues.

-Good Range
-Triple Antenna
-ugly green base
Some problem with the newest driver online (v1.4).
if you happened to update  the driver rather than use the one in the driver CD (v1.3), you might be really screwed.

After update d my driver i cant even boot into my windows.
It become BSOD before you can log in (right after the boot screen).
I have to remove the card before i can boot into windows to search online for solution. Then I have to reinstall the driver under safemode.

It does not just happened to me; I'd read other similar problem online before i got the solution.

System : Windows 7 Ultimate 64 bit.

Easy to install and set up
It's draft N
I'm a bit upset that the title of the product doesn't mention that this is a Draft N card. I recently bought an 802.11N router and when I went to my PC to connect I couldn't find the router! D-Link's draft N does not work with my Linksys E3000 router in N mode so I'm still stuck in Wi-Fi G land. Otherwise it works fine when connected to 802.11G networks.

- no hassle installation with Windows 7
- fast
- good range
Plugged it into a PCI, booted up Windows 7, driver was automatically loaded by windows, never had to configure anything or install anything. Couldn't ask for anything better.

-Worked out of box and automatically installed onto my P8Z68 Asus mobo and Windows 7
-Costly compared to many other internal cards
-The best thing about internal cards is if they work out of box without extra installation. It gives you that warm fuzzy feeling inside and also saves you a tonne of time transferring drivers from another computer.

Simple installation, good signal strength, decent speed
all in all, it does what it should. works through multiple walls fine.
