Actually I feel that at speeds greater than *50*Mbits, most of the bloat
moves to the wifi, but perhaps I should qualify it more, Modern wifi can do
almost 2gbits a few feet from the AP, but still has a dynamic range of
5Mbit to 2gbit. Interference, contention, range, all factor into when you
hit a FIFO "cliff", and stay there.

I wish I knew how many commercial APs outside of eero, cisco meraki,
gfiber, and starlink have adopted fq_codel. Certainly I am pleased as punch
at openwrt's adoption. And seeing at least a few fiber folk shipping better
wifi.

Moreso, if only more vendors did a RvRvlatency test like:
http://flent-newark.bufferbloat.net/~d/Airtime%20based%20queue%20limit%20for%20FQ_CoDel%20in%20wireless%20interface.pdf

A hugely mitigating factor is people self adapting to move closer to the AP
(or mesh), another is most traffic never cracks 20 mbit for very long.

I am sad that every coffee shop I frequent save one, has horrible
bufferbloat, but it  usually only shows up when you try to do s
videoconference.
