Update remote Powerline adapter

I have this kit:-

D-Link DHP-307AV/B 200 MBPS PowerLine Homeplug AV Network Starter Kit Note now updated. Will my old model work with newer remote adapters; prepared to replace master as well as remote.

I now have a situation where I need a new remote adapter that has two ethernet sockets (2 wire only devices to connect) and wifi, preferably both 2.4GHz and 5GHz (1 wifi device 2.4Ghz only other has both 2.4Ghz and 5GHz).

As a side issue it seems my, now old, Sony TV requires CAT 7 cable; can't get network connection from the original remote D-Link adapter using CAT 5 cable?? Why?

Any advice please?

Bought BT triple unit kit. BT units do not seem to speak to my D-Link units. However all work fine on my home wiring. D-link are now spares

As for Sony problem. Cat 7 makes no difference but updating TV software did.
