[Make-wifi-fast] Make-wifi-fast Digest, Vol 26, Issue 2 - Thanks and question on whether the Make-wifi-fast code is in the Ubiquiti wireless implementation.

Rich, I'd like to thank and acknowledge the excellent work done by yourself and all the technical contributors.

I've been using and benefiting from the good work done on my routers using fq-codel and cake as well, mostly on a TP-Link Archer C7 with OpenWRT and LEDE builds, and that has worked well to control latency on my internet connection.

I've also been a fan of the Ubiquiti Unifi wireless products and have used them at home and for many small business customers.  I have noted that they have implemented Airtime fairness and that is great.

Per your note below stating some of the results, in particular I am unclear on "- A few commercial products - notably IQrouter and Ubiquiti - are shipping a good SQM implementation in their products"  I do know that Ubiquiti has implemented SQM in their routers, but I have not used their routers, but I am very interested if the Unifi AP's have implemented any Make-wifi-fast code, because I have not seen any references to that in their release notes or in other sources.  Also, there do not appear to be any settings in their management interface to enable or configure any SQM, fq-codel, or Cake configuration settings, so I would think there is no Make-wifi-fast code in their current or beta wireless implementations.   They do have "Airtime Fairness" and that has been great, but I do not know if that is due to using Make-wifi-fast code, or their own implementation.

I am interested in any insights you can provide on this, and also in general whether any commercial products have or are planning to implement Make-wifi-fast.    It would be great to see this be implemented in many commercial products so that this ultimately benefits all end-users and becomes a marketing advantage for manufacturers to help spur implementation.

There have been so many improvements in so many ways...

- Cake is the acknowledged winner in SQM

- Make Wi-Fi Fast has removed a couple orders of magnitude of latency in the Wi-Fi stack, and Airtime Fairness has eliminated the Wi-Fi Paradox.

- All this is Implemented in LEDE, so it's available as a (somewhat) straightforward install on hundreds of different kinds of routers. As a side note, LEDE and OpenWrt are working toward a merger, with a unification of the development efforts.

- A few commercial products - notably IQrouter and Ubiquiti - are shipping a good SQM implementation in their products. 

Let's all take a moment and revel in solving some of the major annoyances in networking.

Best regards,

Not only did that firmware reduce bufferbloat, but it showed that DNSSEC and IPv6 could be implemented in "normal" home routers without any kind of jiggery-pokery. Field reports at the end of 2014 showed that build was very stable - we had lots of reports of 80 day uptimes, and a high of ~140 days.
