High Packet Loss Issues: Arris TG2492S Router, 30Mb/s Coaxial Cable, Ping Spikes up to 10,000ms

Hello, I recently connected the internet to multimedia. I sometimes play one game online and unfortunately there are large ping jumps up to 5000-10000 ms, I assume that it is the fault of losing a lot of packets but I am not a specialist for this, so I decided to ask for help to determine the actual cause of the problem .

What I know about the network:
30Mb / s, coaxial cable splitter for tv and internet.
Arris tg2492s multimedia router

here are screenshots from the winmtr program and pingplotter, in addition, I decided to do tracert on 1 multimedia server on the way,






I did more tests but saved them to a text file but most of it looks like this,
router 30% loss,
10.141.0.1 ~ 90%
and another mm server also about 90%

I will be grateful for your help, I hope that the information provided is sufficient.

Regards Grzegorz.

Edition:
I will add that the router is 50cm from the laptop, and connecting it with an Ethernet cable does not change anything in the graphs.
8.1 64bit win computer system

At the moment of the cuts, despite the fact that the game stops connecting, I hear normally on teamspeak.

192.168.0.1 is your router?
router model?

The router as I wrote in the first post is

Arris TG2492S
it is owned by multimedia and I cannot log in to it, all I can use ebok is to set the WiFi password and the channel, but changing the channels does not change the situation.

Yes 192.168.0.1 is rather my router because what else? As I wrote, I can't log in to it.

here is a photo of working on the cable about 10 minutes

Run cmd.exe, type

ping -t 192.168.0.1

Does this ping also lose packets like in ping plotter?

Added after 33 [seconds]:

Boot into Safe Mode + Networking, does that change anything?

Ping -t on the router shows no ping loss on average 1-6ms maximum 20ms, it took me a while to start in safe mode but I finally managed and unfortunately it does not change anything, I think a short test shows what is needed.

Apparently trace packets from the plotter's ping are blocked / ignored.

Try multiple cmd.exe "ping -t xxx" windows where xxx are consecutive traceroute routers until you find the bottleneck.

ok i did, from the second laptop i hope it's not a problem.
I will throw in a photo but I will describe it first.

1 after the router, I do not know what it will be, a box on the cage or something I do not know. Request time out.
on each subsequent one from time to time there are losses from 2 starting, although I think it wasn't until I started pinging around server 9 but it may seem to me, I will try in the afternoon to do it better on my laptop with a mouse because the touchpad is for me divine punishment. I will also put in a comparison with 2 computers that could also rule out computer fault.

What is a bottleneck? And am I able to use a ping plotter or something else to tell which server is not responding at the moment? Since not every packet loss corresponds to in-game freez, but I am able to locate which by playing.




I throw symmetrically made ping, here is laptop No. 2, for WiFi


Here is the laptop No. 1, connected with a cable,

Do "ping -t" without playing (eg to the first 5 routers from the traceroue list), interrupts on some router? ie what% losses are on a given router, you save the results.

then you test the ping while playing, and look at where it stops and compare it to the results without playing.

I see ping first on x.193 router, so that's the bottleneck.

Use wireshark to determine packets per second PPS while playing

The photos I uploaded are with the game turned off, in general, testing while playing is a difficult topic because I don't have much time to play but I managed to establish that even if I have packet losses on the first servers, it did not result in lag, i.e. they were not synchronous, And so, while searching, I tried to ping the last visible address (because later there are 5 invisible and the recipient) and it matches perfectly, 1 address before there is no loss in moments of lag. Could it be this router to blame? It is definitely outside the multimedia backbone network in such a case whether it is possible to bypass such a point either alone or by asking multimedia for help.

Generally speaking, the pingplotter does not show such losses anymore and the initial servers stopped having red stripes, maybe they improved something because I already reported it in multimedia.

Only by redirecting packets through your VPN server (e.g. vpnonline en), but this does not guarantee success.

And if ping -t shows lag loss here, and 1 before not, can I take it for granted that this router is the culprit or is it not certain?

Certain - no, but it makes the suspicion more probable,
the role of the router is to route the packets further, not to respond to pings.

Similarly with traceroute, routers don't have to send TTL expiration notices in the packet, most do, but it's not the router's responsibility.

I managed to solve the problem, it was not actually multimedia, but one of the routers on the route. I used OpenVPN and the mydevil.net servers and everything works as it should.
