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...
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.
Summary: I've had problems in the past with trying to find a good network adapter that works out of the box under Linux. I've been accustomed to spending a few days trying different drivers and searching the forums, until eventually I get it to work with some kind of hack like a patch or an ndis wrapper.
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.
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...
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.
