I=92ll toss in my two bits.  A new computer I purchased last Christmas
tore up my wife=92s AM radio listening.  The solution was to add an
additional AC line filter on the outside of the computer.  This was
because the switching power supply on the inexpensive off-brand PC
switching power supply did not have adequate filtering on the AC line
side and the switching noise was radiating throughout the whole house.
So you might want to explore that possibility.  It sounds as if you=92re
picking up some sort of radiated noise.  Your LAN connection generally
uses isolated transformer coupling and shouldn=92t be able to
significantly radiate.
