But our ISP base is mostly smaller, rural ISPs with the usual challenges using legacy copper or older DOCSIS deployments. But I have also seen benefits on many a higher-capacity, modern infrastructure. Not sure how they allow bloat on some of the setups, but they do, and a CPE with a decent AQM (like Cake) makes a measurable difference.

Also nice that tests like the DSLreports.com speedtest, who grade packet-loss (the usual congestion signaling) as ‘Quality’ now consistently grade lines as an A in that metric with ECN signaling. 

Indeed, I brought my IQrouter along to Montreal, so Pete, Rodney and I are using it in our AirBNB as a substitute for the rather decrepit D-Link router we found already installed.  The latter was using 2.4GHz only with 40MHz channels, in a dense urban area, with predictable effect.  The ISP appears to be Comcast…

…and the IQrouter works very well, even though I haven't bothered changing it from the 10M/4M settings I use at home.
