5This little thing is awesome!
By Tony in SF
----------------------------------------------------------
UPDATED: January 23, 2012 (Update section below)
----------------------------------------------------------

Installed January 14, 2011 and still excellent. I expect this thing to last at least until December 21 this year, when of course the Mayans have scheduled the world for demolition. :P

Here's my take on the TP-Link TL-WN722N Wireless USB Adapter:

-------------
POSITIVES:
-------------
** It really, really works like mad. ** I get constant download speeds of 12Mbps+, which is close the the max of my internet bandwidth.

- It's very cheap cost-wise for the great performance it gives you

- It's small(ish), though it will look big connected to your laptop

- Comes with a 3' USB extension cable which I definitely recommend using. It helps position the device, and keeps it from crowding your laptop or from being destroyed by being knocked out of your PC's front USB port.

- Has a diffused green LED under the white plastic to let you know it's working, instead of the blinding blue LEDs that everyone uses these days. The light turns off when it's not powered (like when you hit Standby on your PC). NOTE: It's still annoying in a dark room when I'm trying to sleep, but a few post-it notes helps that.

- The software is relatively simple to install and use, and allows you to use other products to manage your WiFi instead.

- The current driver, software, and documents come on a mini CD and are all up to date with what's available on TP-Link's web site

- The documentation is good, but it could use some more detail.

----------------------
MINOR NEGATIVES:
----------------------
- The TP-LINK Wireless Client Utility is functional but could be more intuitive. A configuration "wizard" would be a good improvement for manual configs. (It has been updated as of Jan 5, 2012 - see below)

- Manual configuration (which you need if your network is securely hidden and requires a pass code) isn't well-documented, though you will be able to get it to work with the document, and maybe a little trial and error. If your setup is totally open security-wise (this would be BAD), you will have no problem with the software.

- Even if the driver is installed incorrectly, the client utility may report enough information to make you think it is installed. When in doubt, do a complete removal of the software and drivers and re-install.

- The QSS software that comes with the device is ONLY usable with other TP-Link products. Don't bother installing it unless you have a TP-Link Router/Access Point that has QSS built in. (As of the client update on Jan. 5, 2012, it appears to be installed automatically)

------------------------
UPDATED 01-23-2012
------------------------
- I've kept track, and this device has worked well even with interference from Coronal Mass Ejections from the sun (sunspot activity), though I have noticed that the performance decreases (could be other things along that long internet path, as well).

- I now have a TP-Link TL-WA901ND 2.0 Access Point, which this device works well with. Unfortunately is does NOT connect at the advertised "150Mbps" potential speed when it's configured to do so, but I never really expected it to. My max internet connection of 13Mbps is far below that high rating, anyway.

- The latest WiFi utility for this device is up on TP-Link's web site as of Jan. 5, 2012, and I'm a bit disappointed with it. On the plus side, it is probably simpler to use - which is a good thing for most users, but it's been dumbed down to remove all of the extra connection info power users like me appreciate. The message windows are also annoying and the English grammar is sometimes embarrassingly wrong. It also looks a bit cheesy compared to the previous utility version. At least it works well.

- It is difficult to tell if the actual hardware drivers have been updated, because software info on the page for this device is really incomplete. It looks like they are not updated since I originally posted this review.

- I still benefit from disconnecting and reconnecting the device once in a great while, but the problem that causes the lowered performance could be my PC, the access point, or electromagnetic interference. Hard to say.

- To date, 4 people were helpless in the face of my review - maybe it put them to sleep. Thanks very much to everyone who took the time to click "Yes".

My installation experience
-----------------------------
A friend of mine needed a WiFi adapter since she moved to a location that wasn't wired, so I recommended this to her based on the great reviews it's received. She successfully and easily installed this device on her work laptop, and was extremely impressed with it's ability to drag a much better signal out of the almost inaccessible 802.11n WiFi router located down stairs, the signal of which is blocked by many walls and turns.

She also needed to install the device on her personal PC. Unfortunately we spent hours over chat trying to get it installed and working, and FINALLY got it done after completely removing the software and drivers that she had installed, and then reinstalling those drivers with my guidance. It was only at this point that she said, "Oh yeah, I kind of passed over that part" where XP asks for confirmation to install an unsigned driver. AHHHHHHH! Well, now it works. :) The signal is not fantastic, but it's 4 times better than it used to be (for her laptop) and is good enough for her PC. It definitely works. So one lesson for you is: Please do yourself a favor, and let your operating system install the driver properly. ;)

The night I helped my friend with her WiFi, I received and installed my own TL-WN722N adapter, to help her through the install process and to replace the D-Link 4300 router I was using as a WiFi receiver (firmware v1.8 has bridging).

After installing this little thing and adjusting the antenna, I got download speeds almost twice as fast as before to the aging Linksys 802.11b-only wifi router downstairs. I then spent some time replacing that Linksys device with the D-Link 4300, turned on Super-G, and got almost 13Mbit down and 1.7Mbit up, which is more than four times what I was getting before on download and upload. The download speed varies between 8Mb-12Mb - it probably hits 12mb because of Super-G infringing on other people's signal space :P - but the upload speed has been really constant at 1.7Mb or so since I installed it, even to the Linksys router. The download speed is almost as good as I can get by plugging in a 75' network cable directly to the router.

So this little thing really rocks!

FYI, DSL Reports has an excellent set of speed reporting tools, as well as info on increasing network equipment and WiFi performance. Check it out! I'd enter a link, but Amazon would probably only delete it.

That's it, another novel for my reviews. I'll update this over time if anything new happens...

4Great Product!
By Ryan McCrillis
I am a soldier in Afghanistan where I live in a tent. The nearest internet hotspot is about 120 meters away behind a 1 foot thick concrete blast wall. Before I purchased this relatively inexpensive 'high-gain' antenna I had to leave my tent and walk outdoors towards a signal to connect to the internet.
Now, not only am I able to connect, but I have twice as many choices of networks to connect to. This little gadget is awesome! The upload and download speeds are good enough for SKYPE. It is one of the best devices I've purchased since I've been here.

5TP-LINK TL-WN722N
By R. Berry
It has my respect for two reasons.
First, It pulls in a signal from somewhere, not on our acreage.
And secondly, anywhere I've tried it, it has an outstanding, full five bars signal.
This is paired with an AT&T 2wire wireless G router and has no loss, I can find.
The Only con is you must D/L Win 7 driver from their site, which took 30 seconds to locate and download. XP and Vista drivers on disc supplied.
It made my first wireless box happy, the rest remain hardwired, "for now".
Simple, Painless, Secure.
If you are looking for something reliable, this is currently $20 shipped to your place.
Get you one.
To test I had 4 secure pages and 2 different HULU channels playing and a few web pages, all open concurrently, and each was clear and fluid.
