One should not, and renew everything forever, because not everything that is new is equally good !!!! Had been the high-speed 85, and thought the new may be what faster Sturdy, power-saving, because you can turn the LEDs off and because it does not waste outlet, now the disillusionment came quickly, none of the connector has been recognized not wnn they read alone in the socket, then it is also possible that someone has no free outlet more, or a room where the outlet behind the cupboard, fridge etc etc 1000 possibilities, making this customer then with the new devolo dLAN 500 Duo + Network Kit ?? ?? On the wall nailing ??? Bin something of Entäuscht and simply can not get over how something new can build the much worse and useless than an older model ??? This also more expensive ..... OFFERING The policy you have to try not at first probably understand ..... The Old High Speed 85 One can also confidently in a Header that work always stuck, simply enter install software code and get going, so I would have duo + Network Kit desired by the devolo dLAN 500 but was nothing ... So my advice stay away unless you're looking for a challenge, and has a lot of time and nerves left .... yes and a sense of tinkering course :)
