I'm leaning towards going back to the idea of disconnecting their systems

Or just disconnect everything since he has his Linksys router in there now
and that should suffice for the local LAN side to take pings and such.

Yes, I was planning on doing that tonight, but I didn't make it down. My
only reservation about this is that if I turn off the LAN equipment (except
for the Linksys) and the modem does not go down, what does that prove? It
would seem to support Comcast's assertion that the problem is on the
client's side, but, on the other hand, is it defensible that a modem should
only work when no traffic is going through it?


I think you've stumbled upon an interesting thing with the rogue
connection to send e-mail. I wonder if there are other processes running,
too.

Frankly, I'm running out of ideas, but if you can't unequivocally show
that the problem is with Comcast, switching to DSL may just be a futile
move.

Way too early for that I would think.

With respect, it's not "way too early" for the client who has been dealing
with no internet access every morning for 3 weeks. They are running out of
patience. And a significant challenge is that much troubleshooting is
required, but I cannot work on it every day, and for the most part I'm all
they've got.


What happens late/early in the morning that could be a factor ? Cold,
humidity maybe ?

Perhaps, but the fact remains that this internet connection has been working
fine for years.


What time were these suspicious emails going out and what time do the
failures occur ?

I can find no definite relationship.

Why would data content bother a modem/router ?

The heart of the question, as far as I'm concerned. Comcast has suggested
that the activities of our mail server is causing the problems. And I
continue to repeat your question: What bearing does content and traffic in
general have on the performance (or lack thereof) of a cable modem????
