XR500 Causing Latency & Packet Loss
Here are the PingPlotter results with my PC ethernet-connected directly to Arris cable modem (with no other devices connected to it) in bridge mode:
Here are the results with my PC ethernet-connected directly to the XR500, which is in turn connected to the Arris cable modem (with no other devices connected to it) in bridge mode:
As you can see, consistently getting deep lag spikes and packet loss in the latter case. I have Anti-Bufferbloat selected to Never and Traffic Prioritization disabled. My standard bandwidth is 400 Mbps down and 23 Mbps up. The cable modem is in bridge mode. The XR500 is set to use my PC's MAC address as its identifier.
Any idea what's causing this issue?

Often, the connection literally goes nuts:
- Well for a start your base connection is spiking on its own anyway so that is an issue, the XR500 will not be able to prevent that. The reason that its worse on the XR500 is because you're not utilising the QoS feature at all. Recommend setting Anti-Bufferbloat to 'Always' and put the download & upload sliders on 70%.
I did as you said. At first everything was much better. Now I'm getting massive lag spikes and packet loss:
Could using my PC's MAC address as the router's MAC address be causing some sort of issue with my ISP? Should I reset the router, so that it's showing it's own MAC address, and then call my ISP to tell them recognize the router as THE device connected to the Arris cable modem?
