Style Name: N900 Dual Band Verified Purchase
Rating revised (1 -> 4). Original review kept as-is for reference purposes in case others have similar problems. See final update for solution to performance problem.

------------------------------------
The purpose of a cutting-edge dual-band (and simultaneous at that!) multi-stream adapter such as this is to allow you to create a modern wireless environment using the newest 2 and 3 stream dual-band wireless routers. In practical terms, though, the 2.4GHz radio band really only has 3 clear channels to choose from so unless you live in a rural area the likelihood of getting more than one channel to bind together to get the multi-stream link speeds advertised by the manufacturers is nil.

So, you set up your new multi-band multi-stream router to use one channel of the 2.4GHz band (if you can find a clear one) just for legacy g and single stream n purposes (your smart phone, older laptops, etc). Then you set up the spacious 5GHz band with as many streams and 40Mhz channels as your router will let you claim. Your new laptop probably already has a multi-stream card that can sit on the 5GHz radio band. This TEW-684UB adapter would theoretically be the perfect add-on to a desktop PC in an awkward location for running Ethernet cable. And with simulcast radios you can use the 5GHz for your main connectivity and the 2.4GHz band for monitoring the rest of your network with free software such as InSSIDer.

I read the mixed reviews of this device and as usual I thought I would be smart enough to make it work to my satisfaction.

Style Name: N300 Mini Verified Purchase
Product works well. Shipped to me with v1.0 of the software -- had to get v1.1 from the website. Also, it's a little large, so it will block things that are very close (e.g. another USB port on top of or right next to it). Trendnet includes a small (about 2") USB extension cable to resolve the problem, though that's a little awkward. On the other hand, probably all wireless N usb adapters will have the same problem, because of the extra antenna & circuitry. Range and throughput are excellent, and it doesn't keep dropping connection like some adapters do.
*edit*
FWIW, I've verified that this is compatible with not only Trendnet Wireless N routers, but also Linksys WRT600 and dlink dir-655

Style Name: N-Speed Verified Purchase
The good:
Received the product quickly and plugged it in and was up and running at N speed in ~10 seconds, not too shabby. Speed was far and above what I ever got with G, and it works all over my house.

The less than good:
Despite the 300mps claim, I'm pretty sure that the theoretical max of this card is locked at 150mps, and unlike every other wireless card I've ever used, the reported speed does not lower automatically based on real time performance statistics, it always says "150mps".

Why oh why do companies insist on putting OUTRAGOUSLY bright blue lights on things? I had to put a piece of electrical tape over the blue light because it was lighting my bedroom...

It also gets pretty darned hot - which so long as it keeps running doesn't bother me, but experience has shown me that devices that run really hot don't tend to last.

Overall a good product, but I can't give it 5 stars.

Here is how to make it to work:
Install the driver utility before inserting the USB adapter. Running the CD that came with it first is a good way of doing it. Downloading the latest driver utility from TrendNet web site and running it first is another. Actually this is the best way while you are waiting the adapter to arrive, so all you have to do later is to plug it in. The third way is to let Windows 7 to install it for you automatically (if you are running Windows 7, 32-bit or 64-bit) by directly inserting the adapter, but updating the driver might be a hassle. Seemed to me you have to unplug it and then update the utility. If you inserted the USB adapter first and couldn't get connection (maybe that's why some of the reviews here are bad), don't worry. Unplug the adapter and start over. Don't leave the adapter attached when you try to install/uninstall the utility.

SPEED:
Some reviewers said it would always display 150 mbps regardless of the true connecting speed. I was also curious about this and spent some time to investigate. It turns out this is not true. The adapter max out at 150 mbps when it is running at normal connecting speed (i.e., the communication speed between this adapter and the router). This is an indication that you have a good router signal strength. However, when the signal strength or quality is poor, it WILL show lower speed. I have seen 120 mbps and even 60 mbps at different locations or after running the computer for a long time, in which case I would change my location or just put the computer to rest a bit. Also, 150 mbps is not the speed into the Internet. The maximum speed between the Internet and your modem is determined by your ISP (DSL or cable company), and it varies depending upon the broadband Internet package that you pay for.
