Network Round Trip Time Spikes ever few Seconds on Orbi ax4200 RBR750

[Zipsy]

When pinging google on command prompt the ping rises occasionally, but when playing games like valorant the network round trip time or ping spikes up every like 2 seconds.

Just finished troubleshooting and experimenting with everything I could. The thing that was causing it was actually the power extenders! When changing the router plug into an actual outlet in the wall the wifi was great. It was lightning fast. At least I know now.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

What are the ping results if you connect a wired PC to the ISP modem/ONT and use the free trial ping plotter program from pingplotter.com with out the RBR? 

[Zipsy]

When connecting to the modem everything is fine. No ping spikes or anything and I have also contacted my internet provider to see if anything was wrong on their end. Nothing. V3.2.16.6_1.4.4 is the firmware

I am Also having this same behavior while playing wow, with firmware 3.2.16.6

I also talked over the phone with someone at netgear and they didn't seem to have an answer for it.

I would probably return the 7 series and try a 8 series to see if the problem follows.

It's best if I can just fix it on the router itself since returning it will be hard with everything that is happening right now.

[Zipsy]

how do I find that

[FURRYe38]

Is there another box unit that the RBRs WAN port is connected too or is this to wall jack? If there is another unit, then look at the units stick, in back or under, to see a mfr and model# of the modem or ONT unit. 

[Zipsy]

If the mfr is manufacturer then it's netgear and the model is CM400. I also have have access to the settings of my motem but not sure if I should change anything in there.

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.

I did that just yesterday and everything was fine on their end.

Can you attached a screen shot of ping plot and a capture of the ping command ran from a wired PC thats connected to the RBR. I would disconnect ALL other devices from the RBR temporarily. Change the SSID name temporarily so that wireless devices won't connect. Then run these two tests with you PC connected to the RBR. Test with and with out the game running. 

[Zipsy]

Sorry I am not able to provide a screenshot anytime too soon. But I ahve tried this before and the ping still spikes. Its just that overall ping compared to the wireless is like 2 ms faster.

[Zipsy]

Here is the chart but in game the network round trip time spikes in sort of a pyramid shape. It seems that the real effects of this are apparent in game when it spikes. The first one is an image of the ping when connected to the router.

This is an image of the ping when connected to a satellite
The ping on the satellite is better than when the router is. The satellite is right next to my laptop so distance shouldn't be an issue.

Here is my ping to Google using a wired PC connected to a ASUS wireless bridge connected to my Orbi AX system:

[Zipsy]

Yours looks fine. Mine is weird.

[FURRYe38]

Are ping times the same if you ping the routers LAN IP address?

[Zipsy]

The ping spikes are still there it's just the overall ping is lower.

[FURRYe38]

Do same test with RBS disabled and if you can with the RBR disconnected from the modem and all other devices disconnected from the RBR. IF you still see some spikes, I would presume there maybe some thin in 7 series FW that differs from 8 series FW and something that NG should look into.

Still spiking

[Zipsy]

When connected only to the router the spikes are even worse and last longer.
