XR1000 High Bufferbloat

[Billz]

Recently I have been getting terrible bufferbloat results with my XR1000. This has especially been an issue when playing a particular game. Any advice on router settings to mitigate this issue?

What is the model of the modem/router the XR is connected to and how have you set that to ensure all traffic flows to the XR? E.g XR in its DMZ, modem/bridge mode

Are ALL devices connected to the XR?

What are the speeds you pay for/receive? 

Have you entered those speeds into the router?

How have you setup Congestion Control?

I have a Spectrum ES2251 Modem, with my XR1000 connected to it. My PC is wired to the XR1000, and I use a few other devices over WIFI, all of which are connected. I have never messed with modem settings.

I pay for 600/20. Download is usually a little higher (say 630), and upload is in that range. I have manually entered and  alsoused NETDUMA tools to detect these speeds.

I have played around with congestion control but it doesnt seem to have solved the issue.
