I'm a new customer, and my line speeds seem fine, but I'm getting a lot of latency, and it appears to be at/beyond my cabinet:
the best case pings look great (12ms or so), but I often get hit with 500-1200ms!
this really makes working from home difficult.
any chance this could be looked into?
some example MTRs:

I believe this is bufferbloat. If I upload anything, the latency gets terrible.

related, I currently have an Airport Extreme attached to the Sagemcom F@ST2704N modem/router.
I would prefer to have just a single router, but the sagemcom doesn't seem to be able to be put into modem-only mode 😕

If you have a "previous ISP modem/router", use that in bridge mode instead.

an update, I'm now using PPPoE/PPPoA via a DrayTek modem in bridged mode, so that should reduce the confusion of having two routers in a row.
That said, I still see bufferbloat on uploads:

bufferbloat on uploads will happen without QoS at your end.
