Product Description

The TL-WN821N Wireless N USB Adapter complies with IEEE 802.11n (Draft 2.0), IEEE 802.11g, and IEEE 802.11b standards. Wireless transmission rates can reach up to 300Mbps. The adapter employs MIMO technology and has internal Intelligent Antennas providing even better wireless performance, transmission rates, stability and coverage. At the same time, CCA technology automatically avoids channel conflicts using its channel selection feature. This product supports 64/128-bit WEP encryptions, as well as WPA/WPA2 and WPA-PSK/WPA2-PSK encryptions and mechanisms in addition to the adapters QSS (Quick Secure Setup) feature, allowing users to quickly and easily setup wireless security. This product can also simultaneously operate bandwidth intensive applications such as voice, and video. Applications using a lot of bandwidth that are sensitive to interruptions such as voice and video applications are given priority in order to assure quality. It also works well with other 11g and 11n protocol wireless products.

Features:
1. Provides two methods of operation: Infrastructure and Ad-Hoc.

This product works flawlessly straight out of the box. The installation was a snap. It works best with the small usb extension provided. I use it with an old Dell laptop to connect it to my new D-Link615 router. It connects my network between two buidings separated by a small area of tropical rain forest, a distance of more than three hundred feet,and through three concrete walls.I like the AES encryption for the enhanced security. This has got to be the best product for the price. I was really impressed with the performance..

Purchased this and received it quickly. A snap to install and works better than I ever expected. We have our office upstairs and our wireless router downstairs. Hooked it up to an older(2-3 years) desk top in our office and works like a charm. It’s fast and at such a great price you can’t get a better deal. I am very pleased with this product.

We inserted the disk that came with the adapter, found the adapter #, chose it, and the adapter worked perfectly.

As always, I do some research to determine which product will benefit my needs. One thing that attracted me most was the security aspect of this TP-Link product. Yes, it does everything it says it will do.

What I like most about it is its connection speed. Once the computer comes on, the adapter immediately connects to the router.

My only suggestion is that you must read the instructions thoroughly prior to installation. If you first plug it in before you read the instruction, you may run into some problems.

This is a great wi-fi adapter, and you definitely can’t beat the price. Very easy to setup.

I’ve had a Wireless N Router for some time now, but I always had a Wireless G Network adapter built into my laptop. I figured I’d go for the upgrade, because I could use a better signal with the extended range. I did my homework. I read reviews on EVERY Wireless N Adapter on the web. I came across this TP Link one, and figured it was the best bang for my buck. Well, that couldn’t be further from the truth.

Prior to using this network adapter, I had a 54.0 MBPS connection — the standard for a Wireless G. After hookup, It went down to a variable rate of 14.0 MBPS to 27.0 MBPS. The speed was more than cut in half! I thought I did something wrong, so I went through the installation steps again, and even did research online as to what I may have done wrong. Turns out, nothing.

So the speed was cut in half, but what about the range? Didn’t increase a lick. This was actually a DOWNGRADE from the built-in Wireless B/G router I had already installed on my computer for free!

I’m appalled at the misleading reviews on here, as they were most likely planted. Avoid this adapter at all costs!

Oh, by the way, none of the software passes Verified Windows tests either. Throughout the installation, you constantly get “Warning!” pop-ups.

I’ve been using the adapter now a few weeks, and I mistakingly blamed the TP-Link Adapter for the slow down in the connection. It actually had something to do with my router. I now get speeds of 108.0 MBPS, so my internet speed DOUBLED. I’m happy with my purchase now, and can recommend this adapter.

This adapter is working well so far on my HTPC in the living room. I don’t yet have an N router, so cant review that aspect. This replaced my netgear USB wireless wg111 piece of junk..

Speed seems on par with G and range is slightly better than the Netgear I had.

Driver install was easy on Windows 7, using the Vista drivers it came with. I did not run the installation program that came with it on a mini-cd ( havent seen one of those in a while ) instead, manually installed the driver in the device manager. It complained it was not signed, but loaded correctly without issue.

I didn’t give it a 5 because I didn’t review N speed… Otherwise awesome little adapter.

I bought this device to allow my wife’s Dell laptop to access our new refurbished Linksys WRT-160N router. Now I’m going to buy another to connect our kitchen computer. After installing the drivers the laptop found our network quickly and boosted speed from 54 mps to 117 mps. The USB adapter is a bit large, but the included USB cable makes that a moot point. Frankly for the money you really can’t do much better.

Quick & easy to set up on Vista. I use it on a G network. Haven’t tried the improved speed of N networks.
