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.

I had used mtr for this, it showed 80% loss on one of the ISP's
machines. They told me that was normal, and to use iptrace which used
the same types of packets (actually, the real packets) of http data.
That's how this thread started.

OK, you caught me - I was too lazy to read the whole thread

That sucks, you know...
What kind of cable modem do you use?

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?
wireshark will see what's going on between your adapter on the PC/Laptop and the destination IP that includes, your router, your modem, ISPs routers, destination routers, etc. and will tell you if there are lost packets, missing hops, etc.
more detailed info here: http://www.wireshark.org/about.html
I prefer checking out all the gear first, beacuse you already made a trace route, and it seems that your connection to the ISP its faulty, too many miliseconds gone.

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.
I meant the coaxial cable that comes from the street to your modem/TV set, you won't be able to do this, let that thing to the cable company, you could get harm if you touch those cables, they are not insolated from the electricity.

And did you point out to the ISP that the 80% loss _is not_ normal? Here
is today's mtr from California back to that machine:
~$ host bzq-179-124-9.static.bezeqint.net
bzq-179-124-9.static.bezeqint.net has address 212.179.124.9
As you can see, it's pretty clean right now with only 5% loss. However,
all of the above is subject to change if the path nodes get a burst and
start dropping packets due to high volume. That part is normal - 99.2%
loss is not (http://dotancohen.com/images/examples/bezeq.html). You
might also point them to this:
http://www.google.com/search?hl=en&q=bzq-179-124-9.static.bezeqint.net

etc.
Looks like others have been having similar problems.

Adapter? Do you mean the NIC card? More than one machine on the
network is displaying symptoms.

Thanks, I'd love to use wireshark but I do not have a degree in
network engineering. I usually have no problem learning anything new,
but with wireshark I am having problems finding an introduction or
tutorial that does not assume prior knowledge. I understand that it is
a complicated tool and I don't expect to master it wholly quickly, nor
do I want to, but for simply determining where the packets are getting
lost between myself and any given site or IP it seems too much.

I called the ISP and they want to do a battery of tests before the
send a tech. Those tests mean that a minimum-wage idiot tells me to
click here, download and run this, click here. It's Windows-only, in
other words. They don't 'support' Linux.

Thank you, NoOp. I will demand to speak with a higher-level tech and
bring this up.
