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.
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. :)
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.
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.
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.
-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.
