Another customer with ping/latency spikes - Time Warner Internet

#1
This question is about "Another customer with ping/latency spikes", with Time Warner Cable internet and apps.
  1. Killeen TX, 76542. Single family
  2. Internet only. Subbed to 400mbps.
  3. Netgear CM600
  4. Asus RT-AC3200
  5. V1.01.14
  6. 400Mbps. 198.3, 23.3, 18ms
  7. At times speedtests show OK and other times (most of them) I won't even get past 200Mbps. Even connecting the computer directly to the modem. When I do see correct speeds on the speed test there's always lag spikes, I've noticed one specific router for my route that has higher latency than all the rest and would periodically spike. I've seen over 700ms spikes from it.

  9. From the backyard connection to a female/female coupler, to a wall jack, to modem. Technician was here yesterday and tested all the way from the backyard and said there was no issue there.
  10. Cat5e from modem to router. Same cable used for testing directly from the computer by disconnecting the router. Most devices here connect wirelessly so they are taken out of the equation when testing directly from the computer. I've also tried 2 or three more network cables between modem and laptop for testing purposes. Makes no difference.
  11. Upgraded modem. Switched the flawed Arris (PUMA issue) for my own Netgear CM600. Things improved a bit with the new modem. Less buffering while streaming or high network utilization but latency spikes keep happening (obviusly since they are not caused by anything on my end). Had problem with Arris modem and stil have it with Netgear modem.
  12. Using PingPlotter to log latency data. Here's a good example of what constantly happens with this router. It's always the same router, ( tge0-0-4.kllntxcr01h.texas.rr.com / 66.68.7.105).
  13. New modem corrected most streaming issues. Before modem Netflix started low res and gradually changed to HD. Now even 4k/Dolby Vision content shows faster, but gaming is a whole another story. Gaming depends on latency and not so much on bandwidth, which is where my main problem lies. The constant latency spikes kills my gaming. As a test I set the router ot send all traffic from the PS4 via my VPN provider and I was able to play without the latency spikes, but obviously bandwidth is greatly reduced going trough that vpn tunnel, besides I shouldn't have to go trough vpn tunnels, that's why I pay Spectrum, the least I can expect is for them to do proper maintennace on their equipment.
  14. There's a couple IoT devices always connected but I've tested with laptop directly connected to the modem thus eliminating that possibility. Same results wither way.



All I wish is for a higher tier or someone from the NOC to take a look at that router. Chat/Phone support is useless as the only thing they'll do is reset the modem and send another technician ad nauseum. If I report the problem 10 times, 10 times theyll handle it the same way. This is really furstrating, I know they won't care a bit but I'm close to cancelling since I feel too much time will be spent trying to get them to even listen.

Another customer with ping/latency spikes?

You're really overthinking this. Either the router is going bad, there's interference, or someone connected to it is using something on a device that is a bandwidth hog. That's the explanation 99% of the time for lag spikes like what your speedtests are showing, so I suggest you look into that instead of creating a massive post with your downstream numbers.
