XR1000+CM2000 Latency issues/Rubberbanding several times a day. Everyday.
Models: AX5400 WiFi Gaming Router (XR1000) v. 1.0.0.64_1.0.49 & DOCSIS 3.1 Cable Modem (CM2000) I have been suffering from a weird issue with latency which has shown sporadic packet loss of 100...

Ok so couple of items on the CM2000 modem that you need to get the ISP to correct:
1. Power levels are WAY TOO LOW and all over the place:
https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router
2. The ISP needs to review the Event log and resolve any Critical, Errors seen here.
3. The modems Correctables and Un_Correctables should be all zero on all channels. There is a boat load.
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do. Should help with the correct and un-correctables.
Be sure to power OFF the modem for 1 minute then back ON.

Good advice above!
In addition to this, would you mind letting us know a bit more information about how the issue manifests? For example, when this disconnection occurs, do you still have access to the XR1000s interface the entire time? That will tell us if the XR is seemingly rebooting, or if it's purely an issue of the connection dropping.
Do ALL devices, both wired and wireless, experience this issue? Or does it appear unique to wireless devices?
On the Cox modem's settings page, are you able to put the XR1000 into it's DMZ? If so, do you still experience the same problem after this?

FYI, the CM2000 would not have a DMZ. Its a modem only. đ

Of course Liam,
The issue manifests on both wireless and wired, with cables that were bough a couple months ago.
We do have access to the XR1000's interface. When I am at the dashboard as the problem happens, I will see the bandwidth drop to nothing. If I am doing a benchmark test and the problem arises, yellow lines will appear in the ping benchmark test, saying "packet loss". The XR is not rebooting, its the connection dropping for sure.
And uhm, I will figure out how to put the XR1000 into its DMZ.
