Summary: Purchased this for my new Linux machine and it was easy to connect. I installed the hardware and Ubuntu recognized it right away. Was able to connect in secods. I was experiencing very slow speeds at first but found this thread to easily fix the problem http://ubuntuforums.org/showthread.php?t=1970955. Now I have a stable connection with great speed!
Pros: Easy to install on Ubuntu 12.04 LTS, Stable Connection
Summary: Installation went smooth. 2.4GHz connection is stable. 5GHz connection is unstable on WinXP Pro x64 with multiple driver versions, using the included utility, and using Windows Wireless Zero Config. Set Power Save Mode = Off as some have suggested. No difference. The included drivers and the drivers on the TP-Link site did not work very well on my system (XP Pro x64).
Pros: Easy to install., Connects fine over 2.4GHz AP.
Cons: Frequent connection drops/packet loss on 5GHz AP on WinXP Pro x64., Bundled wifi utility is ugly, buggy and awkward, just install the drivers.
Summary: I would have given this product 5 stars as it does everything I ask out of a wireless card. However, the other day all of my games started minimizing to desktop or entering windowed mode. I'm not talking once in a while, it was within 10 seconds of getting back into the game that it would happen again.
Pros: Pretty good reception, fast speeds, no connection drops, easy setup
Cons: driver issue causing games to minimize constantly or enter windowed mode (see summary)
Summary: Maybe I was expecting too much. Signal isnt as strong as I want it to be, to be exact, I also have WN722N, which is a cheaper model, but they almost perform similarly. The only good thing, is that it is a PCI Card. The utility isnt anything special, to be honest, it is somewhat annoying, I almost always just use stock windows 7 network thing to connect to my router. The signal does drop once every week or so, but it could be my router.
Pros: PCI-E, Atheros chip
Cons: somewhat weak signal, Software Utility nothing special
