To solve the problem I had then bought a DECT repeater of HAMA, who after successful installation actually works well.
The downside was that the encryption must be turned in the box and the handsets and not stand some of the additional functions of the Fritz handsets available.
That's why I had expectantly ordered the DECT Repeater by AVM and after many weeks of waiting then ultimately get delivered.
The installation worked well and the unit has independently carried out an update to the latest firmware.
Now I was finally able to use the additional functions such funny. As Internet radio and podcasts.
However, soon put a sobering because the device apparently does not work quite stable. This manifested itself spontaneously in different kind of failures handsets such. As the fact that you could suddenly no longer choose from one handset to the outside. Or that man could only hear a very loudest noise.
Remedy has here then gives each restart of the device concerned.
But that's not the basis for our family, because priority has here the highest possible availability of the telephone function. And my wife is there little compromise.
On top of that, the range of the DECT repeater turn was not comparable to the repeater of HAMA. This is because it is a whole lot better.
So I decided after a few days to the repeater of HAMA restore the original state again and the return of AVM.
I think that the Repeater by AVM is well suited for someone who does not need a large range of DECT and has enough patience to wait for the elimination of the last issues of the software.
And since I'm sure from past experience that AVM will continue to make improvements there.
