Just once. I'd figured when vint cerf and jim and van and nick weaver all got on this root cause back in 2011 that somehow the concept and problem would have ended up in the public vernacular, and then all the solutions now deploying.... There's a lot of good advice here, actually: https://www.washingtonpost.com/technology/2020/05/06/wifi-problems-question= s/ bufferbloat so easy to fix nowadays[1], and still so badly misunderstood. When you ISP has seconds of buffering, or your wifi, your network goes to hell, but much of the time, the problem is at the isp, and it doesn't help to sit on top of the AP. I like to think that cable is going to get a lot better with deployment of the docsis-pie aqm.... best I can do I guess is point folk at the reddit threads on bufferbloat and sqm for various routers, keep giving talks, pointing at references like https://lwn.net/Articles/705884/ and the more recent: https://gettys.wordpress.com/ pieces... and just hope that more folk actually isolate the true causes of why is the internet slow today, especially on cable access! and dsl and shaped fiber. Bufferbloat (and the related jitter), really messes up videoconferencing.
