I have a home network.

ISP: BT

Extenders: 2x AV1300 3 port power line adapters

House layout 

bottom floor:

Not truly accurate but an ascii diagram of my house the first • is my router on the bottom floor. Second one is my current extender it's about 5/6m horizontally and 3/4m vertically through thick brick exterior walls as I am on an extension.

This causes a loss in connection from my router and has done and will always do this, this extended gives me ethernet ports and an extension by 30Mb so i get 40Mb with it.

Is there a way to have a middle adapter that connects to the main router and then to mine for example on the diagram:

________________

| •3.     |       |          |

so 1 being my router.

1 -> 2 -> 3
