I needed the wireless adapter for an Enphase Energy gateway. The gateway uploads solar data to a website to be accessed by the solar owner. The gateway only works with this particular adapter.

I didn't have to do anything to get this Adapter working with my wireless network. I plugged it in, turned the computer on and it just worked.

Although it doesn't say that it officially supports Linux OS's. I've been running this adapter perfectly fine with the 646-bit version of Ubuntu 13.10. It's been fairly stable and no dropouts. The only issue I've had, is if your network changes (in my case a router change, same network SSID and password), I could only get it to work with a system reboot, re-adding the network did nothing. The other con is that this is large than you think, so it'll jut out fairly far from any straight USB port you stick it into. My suggestion here is to buy a USB extension and plug that in there and rest the adapter somewhere else or you risk stumbling on it and breaking it.

Bought 2 of these, one for my girlfriend and one for me. Works perfectly fine as long as u have a fast internet and router nothing is wrong with this lower class WiFi adapter. If your not a super geek gamer (no lack allow). then you rather buy this cost 11 dollars over a 30 - 50 dollars wifi adapter.

Installation of the included drivers and utilities went well, although once that was complete the configuration utility said it couldn't find the adapter. An unplug and replug of the USB cable seemed to solve the problem without having to reboot or tweak the network configuration. I've had to do a similar unplug/replug one other time in the last couple of days. Other than that it works fine and gives good signal strength to a router about 70 feet and two walls away. Streaming movies run without issues. Speed tests show 10.4Mbps downstream, 3.6 Mbps upstream. The included USB extension cable is nice, lets me move this somewhat large adapter off the directly-attached USB port and put it in a better position to get signal.

Update 1/18/2013 - Seems to always happen this way. Right after I buy something, a better/cheaper version pops up. In this case, another vendor had the TL-WN722N, bundled with a "UC100" USB cradle, for about the same price as I paid for the TL-WN721N. I'm still happy with the 21's performance (despite the occasional need to unplug/replug it to the USB cable.) But I think the 22 is better because it includes an external antenna, promising better signal strength, and the included cradle keeps the adapter from flopping around in some unattractive fashion. With the 22 I get 26Mbps downstream, 4.06 upstream. Clearly the better choice.

I just put this into a 10ish year old desktop-I moved and only can have wireless service. I thought I would have to replace the desktop but it works fine. It is a little slow but that might because of the age of the computer. I will now try to salvage an 11 year old laptop.

In the meantime, I have a laptop the office gave me and my favorite Amazon purchase of all time, a Chromebook, a fantastic compliment to normal computers, for me, and inexpensive.It also can get signals where other laptops fail.

I am the frustrated ownwer of an HP laptop that lacks a certain, what is the word? Reliability! Yes, that fits nicely. Times are tight enough that a new laptop is out of the question for now, but no Wi-Fi was a huge issue. For very little money, this device had us up and browsing again. It is at least as fast as the one HP had built in to the box, and has been much more reliable at staying connected. Rated at 150mbs, it will not be suitable for gaming, but for surfing and email, it is more than we need.
