3 times faster than PLC 200

I have a Netgear GS108T switch GigaByte and a network-based LEA NetSocket 200+, very good material to pass. Transfer times were already good, around 70 Mbps (one floor to another).
With the dLAN 1200, the rate is multiplied by 3 (200/220 Mbps under the same conditions). Note that I could keep my LEA 200 without slowing Devolo 1200. But we must first connect the Devolo, wait for them to connect, then connect the LEA. In case of power failure, one must disconnect and reconnect in the same order.
Not tested WiFi, but know that it easily disconnects (a long press on the button). As my use is punctual, I want to impose my permanent wave bath.
I take off a star because of the price, I find a bit excessive, but I'm not disappointed with the performance.
Edit: With hindsight, and other tests, it turns out that 200 Mbps were bearing down: the connection can blithely climb above 500 Mbps, from one floor to another. Note that even the LEA work faster: I saw up to 175 Mbps!
I tested the WiFi (which can be activated manually or via Devolo Cockpit), it works perfectly, but the scope remains average. I bought a second Wifi to another building powered by the same picture, but more than 30 meters. I will return to share my action.
