Being dual boot Ubuntu 12.10 64-bit and 64-bit Windows 7 here are my results:
- Ubuntu 12.10 64-bit network card automatically recognized. Security key to put on and go.
- Windows 7 64-bit Windows recognizes the device, but there have to put the installation CD for the driver. It works after restart.
Level network quality, nothing to say, it's perfect, my connection is stable, good ping (60 ms) and also faster than Ethernet. The signal passes through a brick wall and falls on the box.
So for this price and with free shipping, go for it.
