Me either. I was an IT professional for over 30 years. I SUSPECT that it is
coming in via the AC line, NOT the CAT-5.

Nope. Top quality cable.

The DSL modem has worked flawlessly ever since we put it in. It is a Westel
provided to us by Frontier.

Yes. I am quite aware of that.

Lucky you. :-)

I agree. I think it is getting into the router through the AC line.

For some time, I HAD constant trouble with the GFCI which is in the circuit
which feeds the washing machine in the basement. less than 15 feet from
my station, would trip every time I was on 40 meters. It hasn't done that for a
couple of years now, though, ever since I put in what I consider to be a
proper ground.
The piping from the city water main is plastic, Even so, the ioncompetent
jackasses (a couple of geology students) who did some modification to the
wiring in this house before we bought it connected the panel ground to an
interior copper pipe which was connected to the plastic main. As a ground it
was worthless.
I replaced the original panel with a 200 amp panel, did a major rewring job (I
am a qualified electrician) and connected that, through a #8 bare copper wire
to 3 ea 8 foot ground rods,driven to within 2 inches of their tops, all wired
together and about 2 feet apart.

You and me both. :-)
