Summary: I have puchased [10-12] of these over the last two years and was truly happy with them until I recently bought the TRENDnet Wireless AC600 Dual Band USB 2.0 Adapter, TEW-804UB. This one (TEW-649UB) performs well but there is NO COMPARISON to the newer model (TEW-804UB)! It's worth the extra money to upgrade to the newer model, the range is probably double and the signal strength for me has been 4-6 times stronger in XP Pro & 2-3 times stronger in Vista Business!
Summary: I bought this because it uses a RealTek chip(RTL8192SU) and RealTek supports Linux well. This did not work out of the box but was pretty simple to get going. It involved downloading and copying a firmware file to a specific location. The directions are here if anyone is interested: [...] It will also work with NDISwrapper but I had problems with it not initializing after suspending using NDISwrapper.
Summary: technically works but freezes on 144p while watching movies... 360p? forget about it switches down to 144p then freezes halfway though a 2 min video. tried driver on cd, downloaded from trendnet website (at 68kb/s) no dice.. even used device manager for windows to install using the win7/x64 folder, installs but does same thing..
Summary: advertised '150Mbs'. have connected multiple devices... laptops and desktops... speeds range from 35-55Mbs much better than G speed... but FAR from N speed. unit works... easy setup... just MUCH slower than advertised.
Unfortunately I have to concur with the lower rating on this one.

Summary: I recently acquired use of my resort's free hotspot for my computers so I've really had to work hard on finding good adapters. Of the several I bought, this one was the least efficient, bringing in about 6-10Mbps on average. And this is a faster N type adapter. My other Zonets, Alphas and Netgears (N's and G's) bring in from 50Mbps to 130Mbps with lightning fast response and hold the signal perfectly. (I'm about 60 feet away from the signal antenna).
TRENDnet Mini Wireless N Speed USB 2.0 Adapter TEW-649UB (Black)
25 February 2014
Summary: I bought this device in May 2013, and it is now February 2014 and this device just died for no apparent reason. It worked fine otherwise. I guess TRENDnet's quality control departments needs to step it up a notch.
Summary: The adapter worked fine but was quite slow. Even after connecting at 150Mb to the router I would still only get 600KB in transfers between my server and my PC. The adapter would work fine for basic internet use but not for LAN traffic.
Summary: I've always been wary of USB wireless dongles. Tiny, low-gain PCB antennas, crappy drivers. However they do come in handy so I got one for playing around with a Raspberry Pi and backup computers. This one is a bit unusual. It's an oddball 1x2 device which transmits over one antenna but receives 2 streams over 2 antennas. This means it's rated 150 Mbps/300 Mbps - but only with 40 MHz wide channels which you are unlikely to be able to use.
Pros: Excellent speed, 150 Mbps transmit but 300 Mbps receive, i.e. 1x2 antennas, Tiny, Excellent range, Low price, Activity LED, Runs in Linux
Cons: Utility interferes with other wireless utilities, Gets very hot in Linux
Summary: It's about the low profile adapter more than speed, yet I expected a little better speed capabilities on the network even with this little guy. It arrived quickly and as expected, just doesn't perform as well as I expected it to.
