Dave's work is vital, and your support appreciated....
 
https://www.gofundme.com/savewifi - I am one of the people that made wifi what it is - open, free, for anyone to use, any way they wanted - and it seems today  like every government agency and carrier - and even those making the chips - wants to kill it.

I spent the last 2 years of my life designing algorithms to make wifi a lot better than it is today, only to find out a few months back that both the FCC and the European commission, planned to make the results of my life's work, illegal for ordinary people, to install.

The CeroWrt project's letter to the FCC on how to better manage the
software on wifi and home routers vs some proposed regulations is now in last call for signatures. The final draft of our FCC submittal is
here:

https://docs.google.com/document/d/15QhugvMlIOjH7iCxFdqJFhhwT6_nmYT2j8xAscCImX0/edit?usp=sharing

And in PDF format: http://huchra.bufferbloat.net/~d/fcc_saner_software_practices.pdf

The principal signers (Dave Taht and Vint Cerf), are joined by many
network researchers, open source developers, and dozens of developers of aftermarket firmware projects like OpenWrt.

Prominent signers currently include:

Jonathan Corbet, David P. Reed, Dan Geer, Jim Gettys, Phil Karn, Felix
Fietkau, Corinna "Elektra" Aichele, Randell Jesup, Bruce Schneier, Eric S. Raymond, Simon Kelly, Andreas Petlund, Sascha Meinrath, Joe Touch, Dave Farber, Nick Feamster, Paul Vixie, Bob Frankston, Eric Schultz, Brahm Cohen, Jeff Osborn, Harald Alvestrand, and James Woodyatt.

If you would like to join our call for substituting sane software
engineering practices over misguided regulations, the window for
adding your signature to the letter closes at 11:59AM ET, today,

Grrr.... Telemarketers no longer even do us the courtesy of a "live person"....

Phone rings.  I answer: "Hello".
Phone replies, with clearly an automated voice: "Hello, this is Ray".
I don't say anything.
Phone says: "Are you there?"
I don't say anything for a couple seconds.
Phone hangs up.

Unfortunately, browser only based tools can't tell you where the #bufferbloat  is, but at least it will tell you which direction, and how much you are suffering at any given moment.

Note that dslreports tool can be used on any kind of Internet service.

I had forgotten how wonderful the RITE project's video was and had forgotten to send kudo's in public. (I remembered to do so in private).
So those of you (which is most of you) suffering from #bufferbloat  and other bad performance who need to educate the general public about it should watch their wonderful video.  And then go do your part to fix the problems!
  RITE has, since its start nearly two years ago, worked to reduce the delay experienced when using the Internet. The approach is to make small, smart, changes to the mechanisms that makes Int...

I like Vint's quote best: “We can't afford to let any part of the Internet's infrastructure rot in place." For the sake of a secure end to end Internet without bufferbloat, it is essential that systems be maintained and upgraded over the life of a device. They cannot be allowed to "rot in place", or innovation will die.

I love frequent security updates too. However, I want to keep my Personal Computer. The one where I the person is in charge when updates are applied.

Lets separate the security necessary updates from the frills and feature additions, that serve the company more then the user. This constant changing software landscape of the web and mobile based apps (incl. Chrome, Firefox, etc.) with auto updates that are not security relevant are a menace.

Stock firmware on almost all home routers is insecure, buggy, bufferbloated and obsolete at shipment and has no secure update stream. Tell me again, FCC why I should tolerate this in my house????
 
Such a rule is potentially disastrous from so many angles -- security, privacy, bug fixing, new applications -- on and on. This one must be stopped.
An anonymous reader writes: Hackaday reports that the FCC is introducing new rules which ban firmware modifications for the radio systems in WiFi routers and other wireless devices operating in the 5 GHz range. The vast majority of routers are manufactured as System on Chip devices, with the radio m...

+Brian Fitzgerald it is the opinion of many that the number one threat to the Internet is stale code.  The number one thing keeping the stale code in place are rules like the FCC one.  It therefore follows that the FCC is the number one threat to the Internet.  If the FCC were a foreign power, we'd be carpet bombing them.

This is so true, though I believe there are other solutions. Once I was a window system expert; now, my answer is I'm not and others are experts. Once I was an HTTP expert; now, don't ask me for my opinion of where it is, and so on. Experts should reinvent themselves periodically, and never stay the expert for too long.... Life is more fun that way, anyway.
 
Food for thought, especially for all us who are experts in their field...

Yup, on Windows PingPlotter is a good tool; but as I don't run Windows, I had mostly forgotten about it.  As I remember, it has a decent graphical display, rather than mtr's text only tables of numbers you have to interpret.

And this is something you can do today on your Ubuntu system; add a one line long file to your system.  Please do so... You'll like it.

+Philipp Kern The best bufferbloat tool is netperf_wrapper.

In short, anything that saturates the link will do, however.  I did most of my early testing just using scp and ping (at the same time) to a machine I have at MIT.  You can even see the problem by running speedtest.net, and running ping at the same time as the test.
The big problem with speedtest.net is just that it doesn't run ping at the same time as it saturates the link.
