I bought the starter kit dlan 500 Wireless and 2 other adapters to be able to create a network because I needed it in 3 different places of the house. I live in the countryside, the initial reception is not great, the walls are thick, the very big house, etc ... Installation was a bit difficult because of the lack of well made tool: the little diagram that is in the boxes is quite insufficient and most comprehensive guide that is on the CD-ROM is generic for devolo adapters and all cases, and sometimes contradict one page to another. It takes a little guess and then tweak. After much trial and error, therefore, I finally get there, and now I'm very satisfied because it works perfectly and we now really the wi-fi everywhere including on the various outdoor terraces. One downside: the exorbitant price!
