Was this ever solved or even looked at by Spectrum?
I'm seeing the same problem. Tech says signal is OK, speedtest will show pretty close to my contracted speed.. but jitter kills my gaming/streaming activities.
I've used an application called PingPlotter (basically pingpath but graphs over time). No matter where I try the test theres always a hop that will spike constantly..
Here's a screenshot of the issue. https://www.screencast.com/t/HIsbdMPM
Spectrum support doesn't even understand what I'm trying to explain.. seems like their script only tells them to restart the modem and send a technician.. Techs will come and tell me signal levels are Ok, but that's not the problem.
Is there any way to get Spectrum to listen? Really frustrating situation ehn they don't even try to understand you.
