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.

Thanks Furry,
I will lookup where this is coming from. And yes, I do have a default 192.168 address on the router.
I read on another post on the forums that Netgear tends to have issues with false positives, so as I read all the log I didnt worry much.

That IP was from Vodafone, do you play with anyone in the UK/talk to anyone there and if so was it while the issue was happening?
- Yeah Furry, youre right. Inma keep an eye on it. I really dont understand how I am getting DoS attacks. Or why lol.
And no Fraser, we do not have a Vodaphone, but one of my roommates has a phone that was made in Europe. Thats about it. We use our cellphones for most phone calls, and the ocassional discord. We dont really talk to anyone from the UK... so...
UHMMM... now im getting concerned!
Last Friday i got a technician scheduled, he's visiting tomorrow, so I will ask about every single thing you guys have helped me find out. Unfortunately right now I am out of state for work, but as soon as I return this evening I will continue surveilling my network.
Oh yeah!
I have also replaced my CAT5 to a good brand CAT6, as I tested my network on Friday I noticed less jitter. I still get a disconnects but its improved. Hopefully tomorrow is the day of reckoning for this issues. - Vodafone is an ISP/Phone Network not a physical device, it could be absolutely nothing but if the disconnects occurred during the logs you provided then it would point to that. I'd recommend you unplug the XR completely and don't let the tech see it so they completely focus on the connection and modem rather than third party equipment.
- Oh. Hm. No we dont have Vodaphone. I dont know how that can end up on our router.
Okay Fraser, I will disconnect the XR tomorrow and plug my desktop directly to my modem. This way they can worry about the modem, since the issue seems to be with the modem and not wifi strength.
But. Does this mean I might still get issues once i replug the XR? Or do I just leave it disconnected? - It's probably a connection you're making/is being made to you and they use Vodafone as their ISP. If the issue is something to do with the modem/line hopefully they can resolve it, if it's all fine we'll have to rethink what it could be on the XR. Perhaps they can put a block on that IP for you.
- Well, I've been troubleshooting this for so long that I truly get the feeling that its my lines and/or signal from ISP.
That said, tomorrow when I get the tech to actually assist me I will inform you guys of the progress.
I cant thank you enough for all your assistance, it's been more worth than the past whole few months of troubleshooting Have the tech be sure to check everything I posted about in regards to the CM2000 modem first.
- Will do.

The tech came by, and did a quick check, noticed a bunch of corroded cables outside. I told him about the things we talked about and he said he also noticed our signal was insanely low and it was a miracle that the modems of our whole condo complex were even connected.
The cable box for our system was all messed up. [Which means I'm only one of the 9-12 families you guys have helped] He has scheduled an actual team to service our system all around the complex, changed our cables to new ones [in/out the walls] and hopefully by Wednesday we'll have stable service. Apparently having choppy connections due to high bandwidth usage around the houses is an old myth from 20 years ago that I still believed to be true, so I guess I should've reported this a long time ago.
Thank you. We've been having choppy service for 2+ years. We've had 4 techs in that time. This is the first time we get a chief tech to come over so maybe that's why he actually found out all the issues, which of course I wouldn't have known without yall's help.
Now if only I could find out what that Vodaphone connection is...
Thanks for letting us know.
Might change the SSID name or the SSID password to something else on the router temporarily and see if that one device is still seen. Don't tell anyone of the change. Disconnect all wired devices as well accept for the one wired PC connected that your using to make changes.
Should see this device disappear.
- That's brilliant to hear, sounds most likely to be the problem! The Vodafone is probably just a connection you're making to someone in the UK when gaming and likely not a concern.

Yesterday night was the due date for the service, and impressively that same morning a team of like 12 CoxCable vans showed up to the area, and fixed it up to perfection. I haven't had a single disconnect ever since. Tech sent me a message saying they fixed the feeder cable for the whole condominium and replaced a lot of the hardware for the area.
I have changed the SSID name and Password but the device doesn't disappear, but that's for another post, so I think that's it!
Thank you all for your help!
Edit for info:
I did check the cable connection and logs in the CM2000, the critical errors are gone, but the correctables and un_correctables remain. That said, my connection is running smoothly at the moment.
The connection benchmarks show no packet loss anymore, and a pathping to servers showed me a difference in packet loss from 25% to 2%. So I think we're doing MUCH better.
- That is absolutely brilliant to hear, I bet you're very happy with that, as will your neighbors! Thanks for providing an update!
Glad it's working better. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
