Täht: The state of fq_codel and sch_cake worldwide

About 18 months ago, when our home fibre link was just not working for video calls (frequent drops in audio), I figured (thanks to years of reading LWN) that this may be the problem. The wifi router was from early 2010s. I configured a raspberry pi 4 that we had lying around with openwrt and set it up as the wifi router, and it was fantastic. Subsequently we got another router (TPLink Archer C7) as well as another service provider but keep the old provider and the pi as a backup and it's still chugging along 24/7. There's little measurable bufferbloat on the Archer, stock firmware; I'm not sure what queue algorithm it uses but it's "good enough" that I haven't tried to install openwrt on it (though I bought that model specifically because it's openwrt-compatible).

Anyway, thanks all the bufferbloat fixing folks, the openwrt project, and LWN for spreading the awareness!
