    Awesome to hear that you are turning this on both upstream and downstream. Do you know if the wifi stacks in your home routers also have AQM?

The talk links to a just-published paper at https://urldefense.com/v3/__https://arxiv.org/abs/2107.13968__;!!CQl3mcHX2A!XLFMYPw-gnJgHzz_1nF-N7dNeIeT4QD-5wQny8vdAfYE6bzHtVQD3-lqiQI9YwCePfNyng$  (click PDF link in upper right of page) that will likely be of interest to these two lists.
