For the FritzBox 7590, 7580 and the Fritz Repeater 1750E now FritzOS 7.10 available. The newer design with a number of different features, including a small but practical feature: Who works for FritzBox, for example, in the bedroom, turning off all LEDs in turning new. Not only does this cover quieter sleep, but it is also very energy-efficient in the long term.
As soon as you have completed the update (you will find instructions in the text below), you can add the new tabular display with the menu system -> Buttons and LEDs. Here, the lights that strike off can then turn easily and again.
