 Absolutely NO achievable 802.11n performance! January 9, 2009
I just bought this adapter for use with a brand-new D-Link DIR-825 802.11n router. The router was already configured, with several b/g-class devices were connected on the 2.4GHz band and one n-class device connected on the 5GHz band (and achieving typical 802.11n-class speeds of 100+ Mbps.) The router is only 25 feet away from the network adapter, and there's almost a clear line-of-sight between them.
The adapter installed fine, but to my surprise, it couldn't see the 5GHz network. Much configuring and many router+machine reboots did not improve this situation. This is utterly baffling, since the 802.11n network adapter from another manufacturer in another machine can see and connect to the 5GHz network just fine.
It could connect fine to the 2.4GHz network, and it reported a connection speed of 270Mbps. However, whenever I initiated a file transfer from any site, the reported connection speed drops to 54Mbps (the convention for 802.11g), and the maximum transfer throughput was a poky 500Kps (4Mbps)... which is about on par with an average-performing 802.11g-class adapter.
I completely don't understand why this latest-generation D-Link adapter can't communicate properly with the latest-generation D-Link router. It makes no sense.
Bottom line: This is a lame network adapter that utterly fails on its 802.11n promises.
 Wireless for dummies! December 26, 2008

I can't understand the negative reviews for this product. I've never installed a wireless device and I had this fully functional is less than a half hour. I went to the D-Link website and downloaded the lastest drivers and install. The installation was effortless. The only problem I had was on my end. I'm using a Verizon suppplied Westell VersaLink DSL modem/router and needed the encryption key. It took a few minutes to figure out that the key is listed on the back of the box. Once I entered the key the installation was finished. The Westell device doesn't support 4x so I'm restricted to its limitations but the download speeds equal what I getting before with ethernet. I'm using XP sp3 so I can't comment on Vista, MAC etc. I intend to buy two more of these for the other computers in the household. For the money this thing is hard to beat!
Worked just fine on first try! Solid product! December 24, 2008
D-Link DWA-140 RangeBooster Draft 802.1n N Wireless USB Adapter - installed perfectly - works just dandy. Follow the instructions and you will be pleased.
Fast, easy, no problem setup December 22, 2008
I recently picked up a free DIR-625 wireless router from a family member, and needed to get an access point to use with it. I found the DWA 140 on Amazon for about half what the local chain stores wanted, so I picked it up. Setup was a breeze. I was quite ready to spend hours and brain power setting this thing up (as I have done in the past with wireless networks), but much to my enjoyment it took only a few minutes. Just follow the instructions, make sure your router is already functioning, and you're set.
I did the 'manual install' and just punched in my network name and password, and it worked immediately.
It's more than enough speed for my cable internet, and I notice no lag during anything online even with the wireless signal going through a couple walls and a closet. It's never had any trouble connecting, never lost signal, nor given me any grief so far.
You don't see in the pics on Amazon, but it also comes with a nifty USB base that plugs into your USB port on your computer, so you can place it out of the way.
Great little USB adapter. Get it.
Great range! December 16, 2008
This thing really works. With my g standard card I get 5 - 10 mbps and a very low signal from my living room from my D-link N standard wireless router. When I plug in the D-link wireless rangebooser USB Adapter, my speed goes over 100 mbps with a low signal strength. With my internal card I never saw a speed of over 54 mbps even with an execellent signal.
This is a good low cost speedster!
