Excerpt: I've had a home network for well over 10 years now. I went wireless about 5 years ago when my wired router died (circa 2009). I don't know if an N adapter was available at that time, and either way, I was unaware of the pending change, and installed a G wireless adapter--which served me well since.However, I recently upgraded my ISP speed only to learn that my old desktop, which I use as a server for my laptop network, had been connected with an antiquated G wireless...
Works well with Linux- one small hoop to jump through.

Summary: This product works as advertised- the maximum 300Mb/s far exceeds what my ISP is giving me so I have access to my full internet speed. I'm currently using it with Linux Mint 17.1. There is one thing- I got the V4 version. The default version of the suitable rtl8192cu driver that comes with Linux Mint (And Ubuntu as well I think) is faulty, so you'll need to correct that before this product will function reliably.
Summary: I bought this for the linux compatibility; which it has; but I've also used it because my built-in wireless didn't have the range and this thing gave me a solid connection where the other one failed. Happy.
Summary: I upgraded to a Netgear N-router from a Linksys 54-g for the greater bandwidth for performance due to adding multiple iPads, wireliess printer, multiple smart tv's and a PS3. All devices work great the response time with tv's and iPads simultanously running is very acceptable. And the cost of this item is very reasonable for the 300 Mps speed.
Summary: The TL-WN821N is a great 300MBps WiFi USB adapter that works on many operating systems (including Linux/Raspberry Pi). The chipset is Realtek RTL8192CU THE GOOD: + Adapter uses MIMO which means it can operate at up to 300Mbps and generally be faster and have better signal strength that a 150Mbps adapter that does not use MIMO.
Summary: Although it is not as per the picture, it does connect great with my fast U-Verse wireless two rooms away from where the main device is. As if there where no walls in between this device and the main setup. Also the computer is old and a Windows XP Professional. I'm happy, and the computer works great connecting to the internet, and downloading applications like AVG, Windows Updates, etc. Great product. Thanks for having it.
