Model : AV500

Hardware Version : V1

Firmware Version : 140208

ISP :

I have a pair of PLC AV500. Using the tool, the connection between them is weak: 27 Mbps. I have gone through all the recommendations about extensions, motorised appliance noise, circuits, etc. Reality is I want the powerline in that position, which is about 4 rooms away (straight line distance is only about 20 metres).

The question is, if I were to buy another powerline adapter and put it in between, would that somehow improve the performance, kind of how mesh networks work? In effect, do the adapters relay/boost the packets sent around?

Also, if I get 27 Mbps out of a AV500 kit, would it be fair to assume that if I just replace it with a AV2000 kit, would me speed improve, potentially up to 4 times?

Alternatively, the only option I can think of is to have two pairs, each one taking half the distance, and then putting a tiny 10 inch ethernet cable between the two pairs to 'bridge' them, although I wonder if that would just create my own congestion on the powerline which again will affect performance and make it pointless?

Suggestions?

Thanks
William
