First good point: We have a paper form, quality and French, which is rare these days. For a first test, I used the PLC adapters to replace those from my Freebox to quickly test an existing configuration: no worries, everything worked "out of the box". I then used the configuration as an example in the record: Freebox and a computer connected to an adapter, and a second computer on the other adapter. It should of course be in possession of Ethernet cables (Ethernet ports and in your devices, which is certainly the case). Again, ease and reliability are at the rendezvous. With a new home, my grid is new and in good order. Under these conditions, the observed rate is excellent. Incidentally, the LED indicating the quality of the flow is a very good idea. It allows to choose the appropriate wall outlets for optimum grid. Note that the adapters have a secure mode, if one would be paranoid! In the end, this is a quality product.
