This kit includes 2 CPL taken ave electrical outlet above, practice. I bought it to replace a Bewan powerline kit bought in 2009 and that I was too slow. The Bewan was a "tour" for powering appliances and 4 had 3 Ethernet jacks. Devolo This kit consists of a wall socket "normal" but with 3 Ethernet outputs. It takes up less space but requires using a power strip extension cord. As for rates, due to the purchase, it is not obvious. For my electrical installation, not great, I switched about 1 Mb / s to 1.8 Mb / s transfer large files with at least 20 to 25 m of electrical son and an electrical panel with circuit breakers on the ride. There is no miracle. Hence my advice: do not buy at any price the most efficient if the line is bad. For cons, the delivered software, it does not allow optimizing settings (only basic advice), allows a very good vision of PLC connected and displays a flow rate that varies from 17 to 38 Mb / s. I do not know not exactly what it measures. If 17 Mb / s is close to the beach 1.8 MB / s measured, I never noted flow of about 3 to 3.8 MB / s. But we need specific tools for that. Apart from that installation very easy thanks to the pairing buttons. However, I once had a "stall" over connection. A reset on the 2 catches and a pairing and go again. The cause of the stall: I think a power grid terrible. I, on the same line, a chimney heat recovery (Typhoon) that had to cause interference. Another phenomenon: always on the same line, I have a touch lamp (touch-sensitive). It sometimes turns on when there is a significant transfer. And it was nice to turn it off, it turns back on. Proof that circulates many parasites. I did not have this phenomena with the old. I add that Devolo is the brand chosen by Orange to the CPL since its LiveBox and there will be no problem using the Orange kit. In conclusion, considering the price offered by Amazon, here worth it and it is more reliable than WiFi.
