After reading many positive reviews I had already determined the Starter Kit to buy. Then I became aware of the opinion of Kai4u and suspicious. I have at home a Fritz box and wanted to replace the AVsmart + the unsightly cables laid from the hallway and the stairwell. As a technician, but I had my doubts as to the description which is to abort the DSL connection so often. The relationship between DSL signal and hausinternem transmission did not quite evident to me. I finally then but ekauft me a starter kit with two adapters AVsmart +. My guess was confirmed thankfully. After connecting, what was the rest of the connection immediately available actually very quick and easy going. Also the DSL signal is permanently without interruptions.
