The repeater works in basic and options as well as the low power consumption are very good (especially in the AVM-composite).
The problem is, when several devices are logged on to the Repeater (in my case, 2 mobile phones, ipad, laptop, printer, PC) and you want to exchange, for example a larger file between two devices, the repeater adopted. Connections are no longer possible (even for web interface of the repeater).
After short disconnecting the power connection and thus the reboot of the repeater it works immediately. But this is certainly not the intention. Thus, the repeater has failed (at least for me).
