Constant latency spike in online video games?

Hello, we recently replaced our old router (Linksys WRT54GL Wireless-G Wireless Router) with a new one (Linksys EA6100 AC1200 Dualband Wireless Smart Wi-Fi Router) and also received a new modem. The internet works perfectly except for one thing: the latency in online video games. The latency stays at a good, low number, usually 30-40s, sometimes into the higher ones but mostly below 80. However, every 10-15 seconds it spikes up into the 100's and even higher for about 3 seconds or so, sometimes longer. This did not happen with the other router, and so to test it out we switched back to the old one with the new modem and it did not occur. We switched back to the new one, and it occurred again, making us believe that it is the router that is causing it. Everything else about the internet (the download/upload speed, connection, etc.) is perfectly fine, it is just the latency that is messing up. We called customer support and the representative guided us to the router settings and he set up the channel and switched it around, however that did not help. So we are wondering if it is a router issue, or if it is something else? 

 

Also, when looking into this problem we did a traceroute through the cmd, and in certain cases, the ms was in the 100's and more and in other cases, the packet was not acknowledged,  which was apparently displayed as an asterisk. I'm unsure if this is relevant or helpful, but I thought I would provide it. 

 

It is a wireless connection, not ethernet.

 

Thank you for any help.

Re: Constant latency spike in online video games?

use a wired connection, recheck.

 The older router may be more stable.. Why did you get a new modem? Speed upgrade? What model is it and can you copy and paste it's signal level pages?

 Copy and paste a tracert to google.com as well

Are you sure all other wireless and wired devices are off and the computer you're testing with has all cloud, sync, onedrive  programs off? Alll eill eat bandwidth and extend ping times.

Re: Constant latency spike in online video games?

For both an upgrade and because the older modem had a problem where it disconnected constantly. The PC and the router are too far to do a test on them. However, I tried a wireless connection on my laptop while playing games and it seems to not be a problem, only when the PC in the basement is involved. It is the Arris Touchstone TM1602a modem. And I apologize I'm not too tech savvy, where would I go to copy the signal level pages?

And I have checked and all the other programs are off.

Re: Constant latency spike in online video games?

I see two separate issues to investigate:

 

1)  You may have ingress (signal leakage) interference on downstream channel DS12 from  a local TV broadcast TV station transmitting on channel 47 at 627 MHz.  Make sure all of the coaxial cable connectors are clean and tight.  You'll need a 7/16" wrench, plus a screwdriver to remove any wall cover plates so you can check the connector on the back side. 

 

2)  Your troubleshooting confirms there is a problem with that new Netgear router.  Set your router to NOT allow IPv6 addressing, just IPv4.  An iPv6 address has six alphanumeric segments separated by colons, while IPv4 uses just four numbers separated by periods.  IPv6 is not compatible with the VOIP in your EMTA gateway modem, even though you don't have a real telephone instrument connected to the phone jack on the modem.  Your antique WRT54 only knows about IPv4, so problem goes away when you swap it in to test.

Re: Constant latency spike in online video games?

I have checked the cables and they're all in fine, and I've disabled IPv6 with only IPv4 running, and the problem is still there. Could it perhaps be a proximity issue; would I have to bring my PC upstairs? Or might it be a Wi-Fi adapter issue I have on my PC?

Re: Constant latency spike in online video games?

Go through your router setup very carefully.  Make sure you don't have any speed limiting feature turned on. and you are using the TWC DNS addresses 209.18.47.61 and 62. 

If that doesn't turn upanything strange, try running your PC through an ethernet cable connection.  WiFi always adds slight delays and can contributes to instability.

Last, run the TWC Speedtest tool and post your results compared to the speeds you are being billed for.  Speed is a measurable quantity that Spectrum stands behind; minimal ping times are not part of their service committment.

Re: Constant latency spike in online video games?

I decided to bring my PC upstairs and it was worse with the wireless connection, but as soon as I plugged in the Ethernet it worked perfectly. So it seems like maybe a WiFi adapter and router compatibility issue. Either way, I'll find a way to plug in the Ethernet rather than use a WiFi connection. Thank you for the assistance however!

Re: Constant latency spike in online video games?

In case anyone has a similar problem; I switched the wifi adapters, everything works fine now.
