High ping spikes/packetloss

Hello all,

I am experiencing high ping spikes and packetloss while using our internet, and am unable to figure out a solution. I play games online, and constantly experience issues with ping going from 40 to 120, back and forth, for the entire duration I am playing. It happens in every game I play. Using pingplotter, I can also see fairly significant instances of packetloss going on at all times. Download/upload speeds work just fine, but for instances requiring consistent, stable connection like online gaming I am finding most games completely unplayable. I have gone through numerous restarts of all devices, moving the router, wired connection (though very unfeasible anyways for long term use due to layout of apartment and where we can put the router/modem), and a complete replacement of the router/modem. I am at a complete loss of what to do next. Truly, I could do with halving or even quartering our speed, as long as it was actually stable at whatever speed it was.

Hi @SpyA I'm experiencing the same exact issue in Central New Jersey with no hope either,.

I've tried the following steps of escalating remediation: 

* Restart desktop PC, Modem, Router

* I've tested different times of day, early morning, mid-day, middle of the night, no difference in performance 

* I am only using a direct CAT-5 cable connected to the router, tried replacing this cable, no other devices connected

* Confirmed Windows is up-to-date, no pending updates, all drivers current

* Vanilla BIOS config, no overclocking, unusual configurations
* I am not running ANY secondary or tertiary services on my desktop PC, Windows starts with no other applications running (nor third party anti-virus/etc)

* I attempted replacing my Modem and Router (Both Netgear devices) to brand new devices (Motorola and Linksys)

* I struggled to get ahold of support but eventually they told me "nothing is wrong and there is no noise in your line" 

I, too, notice this in gaming but more importantly for work. I frequently get frozen in video conference calls or intermittently dropped from remote desktop sessions at work.

I also used PingPlotter and I see the one hop that frequently spikes is be-98-ar03.plainfield.nj.panjde.comcast.net (68.85.35.37) and I stay steady around 2-4% loss the entire way outside of the first hop of my router. I don't know if this is the route cause, but it is the one that frequently sticks out during testing.

@racerxow​ I am sorry to hear you are having the same issue. I have a tech coming out on Monday (though I am not optimistic about getting the issue fixed seeing other posts without resolution) at this point, so I will pass on what I find out unless someone responds today and we can get some solutions before then

Hello @SpyA. I am sad to hear about the issues you are having, Did you have your tech visit? If so, how did that go?

I'm having a similar issue in Chicago after work being done in the area. Another poster was complaining of the same thing in Colorado. It seems like Xfinity is sabotaging their network stability countrywide.

Same issue outside of Denver. Ever since replacing the router two weeks ago. Looking for options to replace xfinity internet service, as it's too unstable for me to rely on for work.

Hey @SpyA and other folks - I found a workaround solution for this. I noticed IPv6 was recently rolled out in my area, so I assume it is also been rolled out in other markets too. On a hunch, I wanted to see if it had any influence.

I disabled IPv6 on both my router and my device, all spikes and intermittent issues are gone. The difference is night/day and not even comparable. I'm not knowledgeable enough to know the root cause or if its coincidental. For me, my only concern is it works now. Maybe IPv4 gets deprecated or impacted sometime way down the line, but for now IPv6 does not offer me any benefits and is negatively impacting me (at least the current rollout/implementation).

Most Router admin panels will have separate sections for "IPv4" and "IPv6" settings, so I disabled IPv6 there. Additionally I went into my 'Network Adapter Properties' and removed the checkbox to enable IPv6 and restarted my PC. All clear now, I hope this helps you guys too - fingers crossed.

@racerxow​ interesting...

ipv6 has been rolled out here for almost 10 years...so I doubt that's it, but worth a try I suppose.

@hawke_114​ understood, maybe its a fluke or coincidental. For giggles I tried re-enabling IPv6 and the issue returned for me. At least in my instance its occasional spikes or dips. Not catastrophic or disruptive for average web browsing but hell for anything requiring a stable connection.

@racerxow​ Re-reading your response, that is interesting, but does not apply to me. My edge firewall does not support dynamic IPv6 and therefore the IPv6 functionality is disabled. For a sanity check I tried to disable IPv6 at the modem, but the Xfinity modems do not have an option.
