As my FritzBox 7390 is on a house side upstairs and I will sometimes on the other side of the house in the garden to work email with the Tablet / I bought this repeater for the ground floor. The delivery came quickly and the installation worked within 10 minutes from the start. The description is adequate but I have also looked at me to install a video on Youtube. After that, everything was clear. These indicators will light diligently to himself, and in the router the connection appears on this device. But I have probably expected too much of the "new" wireless range. Outside the reception is better but not extreme stronger if I am to believe the WiFi indicator on the iPad or MacBook. Maybe for a dLAN package of Devolo and my Airport Express this would have been better.
