Discussion Massive range on RTT / unstable behavior with ethernet cont.

[tucker000]

Im having the exact same connection issues as another poster on this forum., from 2 years ago. His post is as follows.

>In short, my download and upload speeds are normal at 400 downloads 20 upload. When I do speed tests/ pingplotter / play games, my average ping is generally at 'normal levels' 10-40. But very often it'll spike and have a large variance to it - which affects my gameplay as I teleport around corners/rubberband when I see these spikes on the graph in-game. Shots don't register cleanly and it feels as if I'm at a disadvantage where people see me first or hit me first.

I'm not sure if this is jitter or what the technical term for it would be, but when I look at other peoples' graphs they have generally stable numbers and a tight range on their latency, meanwhile mine goes anywhere from 10ms to 90-200.

>Conclusion:
Issue happens only on my network (no one with same isp near me has this problem in game, and neither do people with other isps but ofc that doesn't matter - not a fair comparison).
It's not based on my router, even direct modem connection has it.
Not based on my computer, other computer has same issue even with a different ethernet cord.
No abnormal pingtest/tracerts.
Down/Up speeds optimal.
No software / hardware errors to cause instability as far as I'm aware.
No QoS/Gaming apps.



I have done many of the same trouble shooting he has. Uninstalled antivirus, disabled firewall, port forward, clear DNS cache, upgrade drivers, got new coax lines installed, new modem, new PC, new ethernet cable, no QoS software, tried upgrading my speeds from 300down 10 up to 500 & 20, still the exact same issue. I have one device my PC hardwired to the computer, and am recieving this issue of "rubberbanding" "teleporting" "skipping". The game that shows the graph i posted with the RTT information is Valorant. This ping spiking occurs in every single online multiplayer game i play. i can feel its effect even when just walking around. The speeds seem to be fine, downloading games rather quickly but there is an obvious issue with latency/RTT. I have tried going through the games support system for troubleshooting to no avail.

The end of the thread that i will link here https://forums.tomshardware.com/thr...behavior-with-ethernet.3720541/#post-22432328 Came to no solutions only conclusions. what can i do on my end to change this problem, and or prove to the ISP to fix it.

So that thread has a lot of information. It also has a lot of information on things that people think are the problem but are not.

The bottom line will be the ISP does not in any way guarantee any kind of latency.
If you call the isp they will just say 8.8.8.8 is a google server and you need to call them

You have replaced all your equipment which means you are not very likely to get this fixed unless it happens to be some setting in the games.

Have you actually tested on someone that lives near you when you say it does not affect other people on the same ISP. Different groups of houses on the same ISP share different wires going to the ISP.


Latency generally not caused by defective equipment it is caused by overloaded connections.

Ping 8.8.8.8 just shows there is some kind of issue between you and google you need to narrow it down.

Run tracert 8.8.8.8.

Now leave pings run to hop 1 (your router) and hop 2 ( the first ISP router).

You almost never see issues to hop 1 but if you do it mostly means there is some software issue on your pc.

Issues to hop 2 represent the line between your house and the ISP. There is the rare chance it is the modem but you have replaced that. What this then means is there is a capacity problem between you and the ISP. You share the total capacity of the connection between your house and the first ISP router with a large number of your neighbors around you. Together you may exceed the bandwidth. The ISP can't really fix this unless they dig up the street to run more wires.

If both these test show no issues then you could continue to ping hops trying to find it. In rare cases some kinds of VPN can help but it depends exactly where the issue is. It will not fix issue in say hop 2 because the vpn travels over the same wires between your house and the ISP.

I have not tried someone elses internet in this same apt building of 6 units. Called spectrum customer support again they suggested trying to add a wifi router to my modem to "help" with uploading so when gaming data doesnt get stuck in some type of limbo. ( i cant remember the exact terminology). Plugged it in, im still hard wired mind you. Still having the same issue in my variety of games. But here are your Tracert tests with some inconsistencies on hop 5, these were done within seconds of each other

That is a bunch of garbage wifi always makes things worse.
Hooking directly to a modem is always best but very few people can do that.

A couple tracert command that you run will not show anything useful. The trace you provide is one random point of data it can be testing error rather than real issues.

You must use a constant ping since it runs for a longer time.

Since you are plugged directly to a modem you can just run the ping to hop1 to start with.

Again your testing shows no real problem with your internet connection.

The problem is either a issue with some software on your machine or you need to collect network data for a longer period of time while the game is running.

So what im understanding is, you do not think random latency spikes on hop 2 from 40ms to 150-250+ is a problem? it happens consistently every 10 seconds! I dont see a need to gather more data. Watching the mtr test over 5-7 minuets, i see hop 2 constantly having latency spikes which is exactly what im experiencing, a delay between servers. When playing any online multiplayer game I can feel the impact from this.

So lets say you are right and there is some issue in hop2. There is nothing you can do about it yourself. The ISP barely promises some bandwidth rate they give no promise on latency.

BUT if you show them these results they will tell you the same thing I am. It does not show a problem you are misreading the data. This does not mean you do not have a problem this test just does not show it.

Part of the reason for this is routers in the path are designed to favor using their CPU power to pass actual user data rather than responding to test messages. They will delay responses to testing to pass other real traffic. In addition many have limit on how much they will respond to to prevent using ping/trace as denial of service attacks against a router.

Real problem will start in some hop and then affect every hop past there including the final hop.

A example I tend to use is say these hops were intersections on your way to work. Lets say one had a big hole and 50% of the cars fall in and were destroyed. You would then not see the final destination report that all cars had arrived to work on time.

In addition the level 1 techs you deal with at a ISP are barely going to know what ping and trace commands are. When you start using fancy tools they will blame the tool rather than try to learn what the report means.

You really need very clear data with very simple commands so you can show the ISP where the problem really is. The low level techs can't fix a design issue they can only fix something that is broken. The level 1 tech though likely can not fix anything that is not related to the connection to your house.
