We have normally three-phase AC current in our houses. The "wiring" networks will work best if they are all connected to the same phase. They also work across phases since somewhere in your house the three phases end up in a single cable where some coupling takes place. However the performance goes down. To overcome this problem there are devices available called "phase-couplers" which couple the high frequency data to the other phases. One additional thing to consider is that the network plug should be plugged directly into the wall plug without using any extension cord because the extension cords using twisted flexible wires are not good in transporting high frequencies. You loose signal strength.

April 2008 15:54 An: Discussion of Hardware and Software issues Betreff: Re: [dba-Tech] modem/router There is an additional issue here which is that electrical power systems can come off of opposite sides of the 240 volt lines. These "wiring" networks work just fine for all sockets on the "same side" of the circuit but completely fail for all sockets on the "opposite side" of the circuit. IOW the voltage brought into your house has TWO 120 volt "sides". In my case one half (roughly) of my house runs on one side, the other 1/2 runs on the other side. I assume that is to "balance" the load on the lines coming in though it may simply be chance. Not sure but I know that this house will not support a "wiring" network, or more literally, you will get signal to 1/2 of the house. I have heard that there is a widget that can be placed across the two "sides" to cause the signal to route over to the other side.
