A major problem is signal interference -- both from the power lines
themselves onto the modulated signal and radio interference by the
propagation of relatively low frequency waves along unshielded lines
with no harmonics suppression. Also, modulated signals are unable to
"jump" transformers, which require adaptations on these points.

Power line wifi repeaters may work nicely in internal premises though.
