HI all i need help to configure 2X TP-Link TL-WPA7510 Kit AV1000 in the same house. First pair is simply connected near the router and work well, then i use an ethernet cable to connect ethernet output of the Powerline AC 750 Mbps Wi-Fi (first pair) to the input of the second pair powerline (ethernet cable pass through many wall) then the last Powerline AC 750 Mbps Wi-Fi (second pair ) is connected to the decoder via ethernet. Usually only the first pair work well, if the second pair work, the first one stop. I hope is a ip problem because i cant read ip with my smartphone. How can i configure it to work together? Sorry for my bad english, hope you understand, thanks for all
