If you're using a CM11A interface, X10's Activehome software
has a "Find other computers" function which will map PLC signals
by housecode and unit.  Perhaps this will help you determine
whether a neighbor's use of X10 is interfering with yours.

(The CM11A will presumably not respond to noise on the line
which might otherwise be causing your modules to switch on or
off.)
