From the technician I received the tip for this router! I grab something before. It now works properly. He has a dual band Wifi. I have my terminal connected to 5GHz! Gigantic.
To set up: In the beginning really not easy. The interface is in English !!! But no problem. On the Internet you can download directly a voice file and therefore everything is in German. To connect the router to the modem it takes nerve and long research. But if one has behind him all works great.
The cloud function I have not tested since I use Dropbox.
From the pure performance I would recommend this product!
