2 star deduction is available for
1. the attached installation instructions
2. the installation CD, which is not her name value
3. Support for missing and help / description on the manufacturing side.
I would also like to briefly explain why. The adapter is an illustrated Quick Start Guide of the adapter. For normal computer users, without or with little basic knowledge about networks, it is almost impossible to configure (or only with luck) the adapter correctly. The condition is that the network interface is set on the computer to DHCP (Automatic IP relationship through the router). Only then can the adapter after it has been connected with network and USB cable to the computer address from the browser and configure. The supplied installation CD includes 2 not useful for the installation documents.
Who then thinks Help on the website to contact the manufacturer will soon discover that there are no other documents to obtain. Even the attempt to register the product there fails, though the adapter is displayed, but can not be register. Further support for this product can be found neither in the German nor the American / English website. Even a contact is not so readily possible where possible.
For anyone who does not get configured the network adapter, should possibly get help from a friend who has at least basic knowledge of networks. As I said it works.
Addendum:
Meanwhile, I have managed to achieve the support of Belkin. This informed me via email that except the Quick Start Guide no further guidance is available. The status of the LED was told subsequently:
Blue: connected, good Wi-Fi signal
Orange: Weak WLAN signal or WPS failed connection
Flashing blue: WPS connection process started
Flashing orange: No Wi-Fi signal
