Corect, Ray.

I was thinking about the original poster's problem as well and what might be
happening is that RF may be getting into the modem itself.

I would recommend putting Type-77 ferrites around the power cord for the
modem, around the line coming from the computer to the modem (is it a serial
line or ethernet line? - either way it can be choked).  Get the large cores
from places like Amidon or Palomar and wrap as many turns around it as you
