Issues with latency and jitter
A few months ago we noticed a lot of issues with latency, particularly while using VoIP. Ran some tests with pics below. This is using ethernet directly to the AT&T provided Arris NVG589, with the network otherwise clear. IPv6 is disabled, though I don't notice a difference with it on/off. Pings to my own gateway and my public IP show <1ms so no problems there. In these pics its average about 350ms but it fluctuates all the time between 150-600ms - it is very rare for it to be low or consistent.
I'm suspecting an issue with the junction box as neighbors have also reported problems. AT&T chat is unavailable through the website and can't get through to anyone on the phones. Please let me know what I can do.
