This is all interesting about the interference. I have my computer about 3
inches from my station and have never had any noise or interference from it.
I have the same router that you mention and not one peep of noise from it.
Am I just lucky?

Robert,
Like you, most of my interference comes from a LINKSYS WRT54G.I
have tried unsuccessfully to use ferrite cores on both ends of the
power cord. The birdie that hurts me the most is at 14.333 MHz. I
have been thinking about switching to a D-LINK router because I have
heard that it is much quieter.
