Now, I am confused.
You said that you have UPnP turned off in the router, you are not forwarding manually, and you said in your first post that..

If Verizon is deliberately choking their interfaces to discourage file-sharing or doing a Comcast-like packet-sniffing number, I'd like to know so I can make the appropriate trouble about it.

 

Huh?
So if you are not manually forwarding or using UPnP, what are you doing?
As you said eariler, the screens of your router looks very close to this guide

I am just reporting to you what I'm seeing.  In the case of UPnP, the router

has a page with a check box.  That box is not checked, which seems to mean

"off", although it doesn't say so.  I do not myself do any sort of port forwarding,

although the programs I run may do it.  I have looked at procedures for doing

it, but it seemed to be a solution without a problem.

 

Right now things are in an odd state here.  I cannot get a web page from

any of the sites I normally connect to, including Google and the NOAA,

except this one, but I can ping other, nonlocal sites successfully.  This is

true across all my machines, so it's not just the one I'm typing this on.

I hope the problem is temporary, whatever it is.

Can I see a screen shot what you saw in the router about UPnP?

 

#2 What program that you run, may do it?

 

#3

Perhaps this is what happened

In regard to #1, I don't see a way to put images here, so I put them here:

http://www.etaoin.com/upnp_state1.jpg

http://www.etaoin.com/upnp_state2.jpg

 

State 1 is the state I found the check box in, and in which I

have left it.  Looks like "off" to me, but you never know....

 

 

#2: I run a variety of browsers, and do a lot of uploading and

downloading, usually via scp, to web sites, from any of the three

machines I have here.  I download movies to the Windows

machine (Netflix, usually).  I have only a general idea of what

these programs are doing under the hood.

 

 

#3: Looks like that was the problem.  It's odd, however, that

only HTTP was affected (as seen from my end).

 

 

I did some more testing with simple copying (scp) and once

again observed serious interference between the download

and upload side of my connection to the Net.  While running

the system monitor program on the Linux box, I can see the

inbound traffic drop from 100 kbs to about 5 kbs during an

upload (scp of a large file).  If I stop the upload the inbound

recovers after a few seconds and goes back to its former

level.  It's almost as if I were on an old-time half-duplex

link.

It is turned off, you have it like that.

 

#2 Do you run any peer to peer programs?

 

For example uTorrent.

 

#3 Ok.

 

To use SCP better over the net, for forward the port that SCP uses to your computer.

 

#4 Does Netflix, require that you forward any ports?

I've run one of the torrent programs from the Linux box.  (It's called

"Transmission" which seems a bit generic.)  However, it seems to

use up a lot of bandwidth and I leave it off unless someone

advertises a specific file they are publishing that way.  I have run

gtk-gnutella, also from the Linux, but it doesn't seem to affect

transmission rates from other processes or machines.  I don't

run any other P2P programs, and I do not run any P2P progams

on the non-Linux machines, partly because of obvious security

issues, especially with respect to the Windows machine.

 

In regard to scp, since I use it to copy locally (between the

different machines on my home network) and via the

Net, I am not sure how I would want to set up the

ports.  Right now it is working pretty well (I think).

 

The Netflix movie viewer, which I run only on the Windows

machine, goes through a considerable procedure of testing

the line when it starts up.  However, I don't have to forward

ports for it.  Whatever it does, it does without my help.

 

I am going to do some more testing to see if I can isolate

the specific circumstances under which uploads interfere

with downloads.  I might even go so far as to look at the

Westell manual.

My problem is not solved, but I think I have to gather more evidence on it

before I can ask the right questions.  It appears that the download choking

during uploads occurs under some circumstances and not others.  I'd like

to isolate those circumstances.  That will take a while.
