Summary: i bought these adapters because they used to use the atheros chipset, which is basically plug and play in linux. the adapters amazon has in stock now at the v4 adapters, which use the realtek chipset. if you aren't familiar with linux, it's a real headache to get the drivers installed and working.
Summary: I got this product hoping it would improve my computers faint network connection. I tried installing the drivers/utility nonsense for hours. I'm in college so I'm literate in technology and have never been so annoyed in my life. They claim this product is compatible with windows 8, there's even a sticker on the box that proudly says so, but it's not...at all.
Summary: This card's drivers are Windows-only. If you searched for it and think it'll work with airmon-ng or reaver, it will NOT. This is version 4.1, which uses the Realtek RTL8192CU chipset. There are two drivers for it for non-Windows systems. You can get the official Realtek driver (Linux and OSX), or search for "compat-wireless" driver (Linux only, but better).
Summary: This unit did not work with my Onkyo NR 616 receiver. Some discussion boards thought it might. I tried it. It did not. I updated all the firmware and did the setup a zillion times a zillion different ways. I'm fairly tech savy...I could not get it working. That said I was able to get it working on my computer fairly easy. It did not work on my mac but I was able to boot into windows 7 and it worked fine.
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.
