2 PC connected to the office on the CPL block with 2 Ethernet ports (XAVB5602) across the CPL block with only 1 Ethernet port (XAVB5401) connected to the Freebox, well, it changes our lives because the WiFi signal low there. Any slowdown or cuts, the connection is excellent. Installation is super simple and sockets in the rear allow not "condemn" an electrical outlet.
