@Solla-topee Thanks for your reply. Yes, all lights are on after pairing and I just noticed that the new powerline seems to now be working with the old one working as the master powerline plugged...

I just bought a pair of new powerlines ( TL-PA7017p). They work fine but when I try and pair any of my old powerlines (TL-PA4010) I don't get any internet signal. I have tried this both ways around...
