I have 3 PA810 Powerline adapters (A, B & C). A & B are in the same room and C is on another floor.

When I run the tpPLC utility it displays all 3 adapters but only shows a data link between A&C and B&C - there is no link shown between A&B. Data is definitely getting between A&B but I am curious as to whether it is having to travel via C to do so.

Do other people's tpPLC connection diagrams look similar, or do you have connections between all adapters?
