As the connection between the sender and receiver is via the mains supply does it matter that the room with the router/sender is on a different fuse/circut to the room with the receiver ? (Surely most homes are similar).
As long as the circuits are through the same fuse box, it will not make much difference, I run a power-line set from upstairs to downstairs these being on different fuses and all I see is a slight drop in speed.
