Still too unstable and unreliable (partly improved, see Updates)

I purchased the repeater primarily because I wanted to achieve a more stable connection with greater range. I've been running the repeater as a LAN bridge to my Fritz box 6360. The ability to stream the DVB-C signal to the WLAN is also interesting for me was not the decisive reason to buy.
Exactly when the properties that are the most important for me, it still falls short so far but strong. In direct line of sight, and a few meters away everything works fine. However, it's enough a false ceiling and the reception is very unstable. Although my Galaxy Tab S is still a good signal strength (WLAN AC), but the connection still constantly collapses. I hope this can be helped along with software updates. The reception with the 6360 and the 7270 is much better under the same conditions.
The DVB-C function is also implemented so far only very rudimentary. In the Android App only SD channels can be streamed. The possibility of calling an electronic program guide to display subtitles or audio channels to choose, bechrieben as on the AVM website, I have not discovered. Only the title of the current program is displayed. When selecting some specific channels the DVB-C function also depends on reproducible. This happens both when using the Android app, as well as in the browser on Windows 7 which is always at the same stations.
I find the idea very exciting product, the implementation of retaining so far but upgradeable. Too bad again a product that needs to ripen at the customer. If the stability is improved by software updates, I will update my review and very happy to be awarded even more stars ...

Update1: Have the reception situation by saying a more central positioning of the router in the house must verbessert.Ich that the repeater is now doing a good job under these conditions. Connection is stable and relatively fast, taking However rapidly in poorer reception situation. Streaming of DVB-C signal to the LAN and WLAN goes well, the bugs described and the functional limitations should however be rectified quickly.

Update2: Fritz OS 6.22! The above-described bugs are now fixed. I've found that inadequate reception situation was partly caused by interference from a wireless headphone. Many electronic devices in the household now use the same frequency range 2.4 GHz (wireless headphones, wireless speakers, WiFi, Bluetooth devices such as FB Fire from TV, phones, etc.). In the 5 GHz range, these disturbances were not available, but the range is very small, so that is changed already at a few meters away on the 2.4-GHz band. If there is insufficient reception therefore always think of possible sources of interference. The reliability (therefore now 4 stars) I am now satisfied. Occasionally, the repeater is still hanging on, so it is necessary that briefly pull out of the socket.

For 5 stars I expect an even higher reliability and greater functionality. In particular, the receiver with laptops is still rather complicated. If guests wish to use the television signal, it is very cumbersome. You have to let the guests directly to the password-protected level of the repeater, or ask them a file available which you need to import the VLC program. On the password level, all settings, including security settings and passwords, editable. Ideal access to television programs on a separate level would be. As I put the Repeater in a rented apartment, are both possible ways to get to the programs, unacceptable. For mobile phones / tablets, there is an app that allows you to access easily.
