Still, I'm not getting very big speed problems on mine, even with those latencies.
Sorry for the basic question, but what are your power levels like?
All I know about the upstream upgrades is they're increasing capacity by 6x (in the first phase) and individual speeds by just under 3x. So it should help things. I don't know if your modem config gets updated as soon as the upgrades are done or some time after though.
