Only the installation under Ubuntu was not easy. Out-of-the-box is not running the stick. That is, he finds the W-LAN, but not connectet. For this you should know that there is a A version with Ralink chipset and a B-version with Realtec chipset, if you go on Linux drivers search. However, the signal strength after installation under Linux is also extremely good.
Especially for the price a super Stick!
Addendum:
Who desperately driver search under Ubuntu, as I was to get the stick follows up and running:
(Ubuntu 13.10)
First dkms install from the Software Center.
Then you need the package 8192cu / 1.8
These best for: "DKMS add ./rtl8192cu-fixes" googling.
The first refers to the results page GitHub with a series of successively entered Terminal commands (under the heading Installation). Start simply re After entering the commands and the stick runs.
