Strange Interaction Between XR500 and SB8200


Recommended Posts

I recently upgraded my internet and had to upgrade my modem from an SB6141 to an SB8200. The SB6141 and XR500 worked fine together, but with the SB8200 there are strange issues like people on Discord being impossible to understand, spikes in games, and excessive jitter like shown in this test:

These problems go away entirely when I connect my computer directly to the SB8200. I've tried turning off the QoS on the XR500 and the problems persist. Does anyone have any suggestions?

Hey, welcome to the forum!

If you're getting spikes and jitter then it sounds like you need to fine tune your QoS settings. What are your bandwidth speeds? I'd suggest you saturate your connection with streams/downloads etc while following this guide and changing your Anti-Bufferbloat percentage until you find what lowers your ping/keeps it stable. http://support.netduma.com/en/support/solutions/articles/16000074717-how-to-test-your-internet-ping

I've tried messing around with the anti-bufferbloat and QoS settings to no avail. I'm having these issues at way below network saturation. I think I figured some things out about my problem though. Both of these tests were done around network-idle, with the important exception of connecting to discord around 11:03.

So what's interesting here is that Discord seems to be causing massive amounts of packet loss when it never had for me before switching modems, and it only causes this packet loss when I'm connected through the XR500.

While it's better connected directly to my modem, it's still not great. I'll contact my ISP and see if they can do anything there. Any ideas why Discord could be causing packet loss while connected to the XR500? Edit: Tech support at my ISP doesn't know what jitter or pingplotter are.

I'd try the same test again but using an IP instead of a URL as the routing was different in both cases, it would just rule out a bad route. Disappointing they don't know what jitter is. If you get it regardless of QoS and only when connected to the XR I would suggest you replace the ethernet cable connecting the XR to the modem as it may be faulty.
