Hi all

I used to have a network with old style Powerline adapters in different rooms, e.g. with these devices: https://www.tp-link.com/uk/home-networking/powerline/tl-pa8010p-kit/

I havesince upgraded to a Deco p9 system. The main Deco is connected directly to my BT hub, and the other two are spread around the house.

Since the Deco p9s use Powerline, is it possible to ADD the old style Powerline hubs into the network too?

I have put one into a wall socket by my TV, in the hope of having a wired connection into my smart TV - but the Powerline does not seem to connect with the network. 

Any advice?
