Hello, I bought the Bbox WPA4220 to connect my TV to my Bbox (CPL) distant approx 15m and receive additional points WIFI. Received on time I have associated with a TL-PA4010P on the advice of a "Amazonaute" (thank you) and he simply plug on live sockets, connect the Ethernet cables and not need miracle dappairage everything works without moire (I had problems with a former LEA kit to 85 Mbps) Regarding the WIFI on my Android smartphone I spotted the TP-LINK Wireless Password and enter the problem without connection. In this regard, I have before connecting the 4220 is a photo of the back to connection indications, I printed and archived in the box which I think is easier than disconnecting note to go but ... So I am perfectly satisfied with this product and delivery Amazon
