The question I struggle with is how to get ISPs to care and put pressure on CPE
manufacturers to fix bufferbloat in their products.
I performed some tests on my Zyxel router, and the WiFi link was terribly
bloated when there were a few walls between my laptop and the router. The
latency almost reached 10 seconds under load! My ISPs response was that some
buffering is normal (some = 10 seconds??) and that artificially saturating the
link doesn't represent a normal use case. Keep in mind that this was at the
edge of the WiFi coverage with a maximum data rate of 15 Mbps, a speed that's
relatively easy to reach. I followed up with an email about how there are
solutions to this issue and that they should put pressure on Zyxel to implement
them, but alas, there has been no response and it has probably fallen on deaf
ears.
