None of my thoughts on the problem were valid.

Turns out the cable line that runs *under* my driveway has
a fault or cut in it and moisture has been slowly attacking
it over the years.

It's not buried very deep apparently. What was happening
is that every time I left the house and the truck drove
over the spot with the damaged cable, it disturbed the
connection and I'll lose Internet. TV was still ok but
the TV service only uses a small part of the overall
bandwidth. Internet and Voice (if you have it) uses a
lot of bandwidth.

Super tech found it using a meter that picks up leakage.

He ran a new temporary cable from the pedestal at the end
of the driveway to the house and all works good again.

He even upgraded to the newest cable box and programmed
two of the voice activated remotes.

Comcast will contact Dig-Safe to check for power lines, etc.
and then they will bury the new cable.

Finally! After almost a month it works great.

It's good that you had a sharp service guy. Some problems like that
can be difficult to find.

Many years ago on our first sailboat, I had a weird problem with the
depth sounder, one of the only bits of electronics on the boat, the
old rotating, flashing bulb type. I traced it down to bad co-ax, but
it was the outer braid that high resistance which seemed impossible to
my untrained eye. It turned out that the insulation had developed a
pin hole leak in the middle of the cable run. The copper braid in
that area had turned into a green mush.
