The installation was done quickly to start small difficulty.
I had the first repeater on 5GHz bridge (standard) with the 7490 connected to check the suitability.
Everything went flawlessly.
Then the change came on LAN bridge and made trouble. Because it includes the LAN cable and has the wireless bridge, there is chaos in the network. Therefore, first the switch to "LAN Bridge" in the repeater setup, and then only the cable ran.
Short explanation of the modes:
The wireless bridge uses the 5GHz Wi-Fi, to connect with the box. The LAN port can be used for a "LAN equipment".
The LAN_Brücke used a LAN cable connection, to connect to the box. It only wireless devices with the repeater can connect.
If you use the same SSID and the WPA2 password in the repeaters and the box, of course, different channels, then the wireless device is always looking for the best receiving station independently and you do not need the WLAN access point switch manually.
The setup in Repeater is also quite easy as it gets the settings of the Fritz box.
And as with AVM common is many things, but usually not all right: Unfortunately, you can not edit the device name and has partially cryptic MAC names. But why some of the name appears correctly, but in others not, which probably do not even know AVM.
The DVB-C function is awesome, perfect picture in SD (HD would be the smartphone or tablet overdone and FritzTV app can always only SD). Who still wants to HD, can accomplish this through the VideoLanClient.
For Fritz TV App: Initially, it was not possible to edit favorites, this AVM has executed but introduced me to the last app update.
About VPN it does not work, because the app requires a Wi-Fi connection. Perhaps AVM improves because after time.
On the whole I am very satisfied with the repeater and can recommend it.
