I also did not want to drill necessarily by all the walls and ceilings and habs times tried with the already long on the market "DLAN". What can I say? It worked by inserting the adapter within a few seconds. My data throughput is stable between Dreambox and PC with 11 Mbit / s via network cable (Switch), via Powerline same speed, but felt. I think the bottleneck here is rather the Dreambox (100Mbit Ethernet connection). Beautiful graphical user interface and good information on the Internet by the manufacturer AVM round off this product.
