Not being an EE, I haven't the slightest idea. US power company

Yes, I have had this problem with
remote controlled power devices. Our 120 volt service
to the house is derived from a 240
volt line from a center tapped transformer, the center is
common and grounded. So we have two possibilities, 180° out
of phase. Does the ethenet signal find it's way, maybe,
maybe not but I guess I will find out. Some times a
different wall outlet will be on the other phase, the other side of the
transformer. In that case you would measure 240 volts
between the two "high"
terminals so it need not
be a mystery if there was a problem.
