As WLAN and DECT repeater in use

I run this FritzBox as WLAN and DECT Repeater to my 7390. Initially, it was relatively difficult to "talk" to the two boxes together to make, among other things because I have connected the speakers via Wi-Fi.

Since the two devices now communicate with each other (after about 2 hours), they have now run for several weeks without any problems together.

Although it is a relatively "expensive" Repeater and hardly worthwhile if you want to extend only be wireless, but who both wireless and want to extend the DECT signal travels with this solution at best (in terms of the power consumption).
