Two cubes are calmly enough for a large house with two floors, if you take three, then you can put it in a garage, for example. The system works in fact in three bands, the second 5 GHz band is used for the transport network, and helps the general one when the load is heavy. In my case, everything is working properly. It is configured through the application, there is no web interface. For me personally, this is not a minus. When switching between cubes, the signal is not lost, which is good. You can connect additional cubes, for me it's not relevant. I did not notice any problems at work, the network does not fall, both cubes work stably and with a normal signal.
