[RFI] Ethernet RFI Elimination?

[Jim]

How much of this is due to Ethernet activity
alone, separate from the huge amounts of 
noise that the cheap switchmode power 
supplies emit?

I have to keep my 3 yr old Linksys switch (not 
simply a 'hub') turned off all the time but for when 
needed owing to the prodigious amount of noise 
put out by its wall-wart switchmode power supply.

For awhile I used a linear ('series pass' regulator) 
lab-quality DC supply to power the Linksys 
switch, but, this was highly inconvienent (size
of the required DC supply, the heat it produced) 
so I adopted the method of bringing up the Linksys 
with its noisy switcher via a switch activated by 
foot on an as needed basis.
