Hard evidence like log data works every time. I have a cron job that
pings the router, modem, and an external site and logs failures with a
time stamp. I run this in two places, inside my work network and on an
external machine.

Here is a good example:

My problem was resolved once I showed TWBC support that their modem
was disappearing while all other hosts stayed up. TWBC replaced the
Ubee modem with a Motorola which fixed it.

In Dewey's case, it sounds like a TWBC internal routing problem.
