Ping stability issues

[cocobutttah]

There's an issue were I get unstable ping later in the day after a restart on the router.

Attached are screenshots of Pingplotter 5 when i have only the modem plugged in vs when i plug in and turn on the XR500 router.

Now at first couple of hours after a restart it runs perfect. its only after a couple of hours this happens (5-6 hrs in)

When in game Modernwarefare it also becomes apparent.

But yeah need some help on this. any would help

Hey, welcome to the forum!

This indicates to me that there may be an issue with the ethernet cable connecting the router to the modem, if you replace this with a new cable do you see the same issue?

[cocobutttah]

No that wont work since it works well when its plugged into the modem same cable. Is there a specific CAT type i should use. i did get two CAT8 cables a couple months ago. But still, that shouldn't be an issue since, a restart will cause it to work again. could it be that my device is defective?

 

[Netduma Fraser]

Those cables will be fine. Well how were these tests done? Were people using the internet at the time? Was QoS used - if so what settings are you using?

[cocobutttah]

Tests were done after restart on PC with no apps running just with ping plotter 5 open. No one was on network just my PC via Ethernet cable. I disabled WiFi features to make sure streams weren't the issue, all was working fine. Turned WiFi back on, worked perfectly fine, QOS was doing its job with 4 streams running in background including discord running. My settings are based of the guides (DumaOS Optimal Settings Guide: Using Ping Assist as a Ping Filter)  (DumaOS Optimal Settings Guide: QoS)  and (How to add your Gaming PC to the DumaOS Geo-filter) Im using Windows 10 1909,  I do use this TCP Optimizer for windows (see attached) and my internet adapter is configured.

Could you change back to Windows Default on TCP Optimizer please and see if there is any difference after that please as it may be interfering with QoS.

[cocobutttah]

Just changed it back to default. 

[Netduma Fraser]

Well it is definitely better! Could you trying using different targets such as a local website or a news website in your state/country please and see what the results are then.

[cocobutttah]

heres a local site ping test. looks good so far

[Netduma Fraser]

I'm thinking it must be related to the target you're pinging then as they're all different but seems like the TCP optimizer was interfering. Try some other sites as well as a little packet loss and some spikes there.

[cocobutttah]

Just ran these tests

[Netduma Fraser]

Does look like there is some jitter there. When you see this behaviour using the XR could you immediately try doing one from the ISP modem please and see if it is consistent?

I am running gbit internet 1000/1000 dont know if it would influence 

[Netduma Fraser]

That shouldn't make a difference, I notice that some new sites were used and the tests were done at different times of the day could you try to keep the tests using the same variables so we can see if there is a noticeable pattern please?
