Most certainly!

Just another PC on the same router. That's all I have access to at home.

Yes.

I have, but that is not in the budget. I'd like to connect without the
router to test, but my ISP needs a Windows-only 'dialer' to connect.
The router can also connect. I've gone nuts trying to connect with
Fedora and Ubuntu without the router, so much, that I bought a router!

I cannot 'dial in' to the ISP that way. Yes, I know that the rest of
the world does not 'dial in' to their ISP via cable modem, but that's
how it's done in Israel. From what I understand (not much) in other
parts of the world the modem is programmed with the 'dial in'
connections and the user doesn't mess with it. Here, it is done in
software running on Windows computers. Or, in a few routers like the
one that I have.

That doesn't sound so weird. I've worked years in automotive repair
and modifications, and I know that connections are often faulty. Will
wireshark see that the connection is being dropped between the router
and the modem, or between the modem and the ISP?

Thanks. With the exception of the router, I've tried two of everything
after the modem. Two PC's, two cables going to the router, and two
cables going from the router to the modem. I don't have coaxial cable
to replace the cable going into the modem, though.

Q: Why is top-posting such a bad thing?
