Wow. I think this is the first post ever to cerowrt-users. I note
cerowrt-devel is where most of the action is, and I'd advise posting
over there (for now).

The point here is that by setting qos on and doing rate limiting
you've moved the core bottleneck from the gateway device or other main
router to cero, which can then manage the problem.

(but only for devices that are behind it. And, yes, if you have
competing traffic on the main router, it will mess up qos)

I generally advise people to FIRST make sure their environment still
works - like printing, samba, dlna, and other services - before making
a version of cerowrt into their main router. Particularly if they have
spouses/kids/work dependent on the network always working.

and then certain releases of cerowrt can certainly be used (after that
testing) as your main router (-17 is looking good, but there is a
patch outstanding on the cerowrt-devel mailing list for openwrt's qos
to lower it's buffering somewhat). See the archives for details.

but if your intent is to help fix the internet, please! do follow
along with our development of cero by using it as a secondary router,
too....

The wiki always needs love, in particular.

Noob questions welcomed, the effort of writing emails in explanation
generally results in stuff getting wikied...
