Not sure why some reviewers had problems with this device, but for me, setup was a breeze and I'm seeing consistent 300 mbps speeds. The lowest speed I've seen is 270 mbps. One suggestion...make sure you use the included USB cable and stand to extend the device so it is on top of or beside your computer, instead of pluging it directly into the USB port. This should provide greater signal strength. Also, in terms of range, I have it a floor below the router, so it definitely is able to handle some distance with objects in between, and I'm still getting 5 full bars of signal strength. There is a big difference between wireless G and N; N is blazingly fast and makes browsing and other internet activities much more fun.
I highly recommend this product.

Can't believe it to be possible, but this unit works less well than the wireless connection built into a 3 year old Acer laptop. Signal strength with the built-in is "fair" most of the time, occasionally "good". I was trying to improve on that and never got beyond "poor" with this so called range booster.

I just got a new desktop computer with Windows 7 Ultimate installed, and I was having a terrible time getting my old wg311v3 PCI wireless card to work (prompting this purchase). Windows 7 did not support the drivers for a few of my other devices, but I was able to just plug this USB adapter in, and 10 seconds later the device had self-installed and was working perfectly. I am using this on my older G series router, but plan on upgrading to an N network at some point in the future, so I appreciate the future compatibility that this product offers in terms of the network and the ability to run on Windows 7. Using the included cradle I can put the receiver up on my desk and get a signal strength and transfer speeds that are pretty much identical to my previous computer's wireless PCI card with a large external antenna.

I like USB portability and compatibility, but as far as wireless goes, I have seen some issues with many products in the past. I wasn't sure what to expect from this but needed a portable N card for my network and am pleasantly surprised, but was still hoping that USB/N wireless technology had come a little further.
SPEED: Good. Delivers consistent 216-270Mbps even at the furthest point from the router I can find in my house.(using Dlink DIR 655 router in N only mode).
RELIABILITY/RANGE: Good, but had hoped for better. No drops so far, but the range is less than my other wireless cards, and most notably, my cheap Belkin USB adapter. This is to be expected from any wireless N product though, and given the consistently awesome speed and absence of dropped signalls, I wouldn't even notice if I wasn't monitoring the range counters during testing and comparisons to my other devices.
DURABILITY: Constructed well. Made of plastics like most of the new products, but very solid construction. Really impressive is the extension cradle which has about a 4' extension cable and could literally be used as a paper weight in a hurricane. My Belkin by comparison seems like it would blow across the room with a sneeze. Heat is always a concern with many new products, but not with this. It maintains a steady operating temperature and has small vents to release internal heat.
COMPATIBILITY: Of note, I have read many reviews of products causing blue screens and crashes, especially for VISTA 64 bit computers. I am using this on Windows 7 64 bit and have no issues except that the Wireless Connection Manager software doesn't run, which is probably a blessing as most 3rd party wireless managment software causes more issues than good and I always revert back to the Windows wireless management anyway. I am not a MAC user, but it came with MAC utilities for what that is worth and I don't believe I came across any bad reviews from MAC users prior to buying, but I wan't paying attention for that either.
Overall a very good product. As with any wireless N product, it carried a higher price tag than the Wireless G products and the range/signal does not live up to all the N hype, but it delivers the N speed I wanted with no issues. This is the mid-level Dlink USB wireless N card at the time of this writing, and maybe the high level offers more range at a higher price tag, but I don't need it. There are some less expensive N cards out there, but read the reviews before you buy, especially if you run MAC, 64 bit, Vista, or plan to use Windows 7 when it comes out as some of the "off brand" and even some familiar branded products are causing some crashes and other issues. For me, this one did not.

This product is advertised as an "N" Adapter which provides "superb wireless performance." The fact is that this "N" Adapter, as I discovered upon receiving it and reading the back of the box, falls in between a G adapter and a 'true' N adapter (D-Link's 'true' "N" Adapter is shown to be the "Xtreme N"), and states that the RangeBooster is not capable of providing a sustained wireless connection. If D-Link had listed that important detail in their Amazon.com description I never would have purchased it! I have a D-Link Router, so I bought this D-Link (supposed) "N" Adapter for my roommates' computer (located in her bedroom not more than 30 feet from my D-Link Router). She installed it, and the highest connection she was able to receive was just under 2 out of 4 bars at 43% connectivity!!! I'm returning this for a full refund. How this adapter got high ratings from anyone is a mystery to me.
