Lag Spikes on Wired Connection with CAT-6 Cable and Cisco DPC3828

[Vulturees]

Hi there, I've been having an issue with my connection on my pc.
here is the picture of the ping on cmd

here is the picture when I use netstat -n

here is the speedtest.net result

here is the test from testmy.net

and some of the details if it is needed

Sometimes it will show Request Timed Out, and sometimes really high ping (>1000)

and here is my specs
Cisco DPC3828
Connected with CAT-6 Cable.

If you need anything else just let me know, I'll provide it. It's been 5 months since I'm having this issue and still can't resolve it no matter what. I've tested from another pc and the results is almost the same the ping will sometimes spike/request timed out.

The stuff you posted shows you have no issues. If it is intermittent you are going to have to get somewhat lucky to find it.

Pretty much you need to leave ping run all the time in the background. The first is a ping to your router IP. If that fails then you have issues with your router.

You can run tracert to some address like 8.8.8.8. You would then run continous ping to some of those ip in the trace. In general the most common point of failure is in hop 2 which represents the ISP first router. If ping to your router (ie hop1) is fine but hop 2 has issues the ISP should be able to fix the cabling or something. Issues past hop2 are hard to say because it internal to your ISP or other ISP networks and only the ISP can really troubleshoot it.

Thank you for responding. Well I tried pinging to router IP before and it sometimes results in value larger than 1.
Just like the image.

And here is the tracert to 8.8.8.8 resulted. I never use tracert before so I really don't know how can I troubleshoot from this data. How does my tracert looks?

That is really strange there really is nothing that can delay you on a ethernet cable. Either the router has some issue or your pc does.

If your pc has any of those so called gamer network things you need to disable it. killer stuff is one but intel has them too now. For killer chips you can get a driver that has all the killer features removed from their web site.

With problems in hop 1 it is going to be harder to trouble shoot. Still all you do is ping the ip in the trace. Try the 10.76.96.1 to start. This is strange that this is a private ip address but your ISP may not give out public IP addresses. If that ones does not respond try the next one in the list.

I don't use any Gamer Network stuff actually, and how can I find/check the one from intel?
Is there anyway I can check my pc for any network related problems?

I tried tracert on 10.76.96.1 and here is the result for that.

Your issue still appears to be between your router and the PC. If you have a intel chipset and you did not install the so called "gamer" stuff you likely have no issues.

This is just guessing. It is extremely hard to find issues that are random. If it did it 100% it would be much simpler.

Just more guessing would be to ensure you have the latest firmware on your router. You could try a different ethernet cable, it is unlikely but it is fairly cheap to try. Maybe there are different drivers for your ethernet/motherboard.

If you had a different PC you could I suppose try the ethernet cable on that one. If the other PC has no issues it means the problem is not your router or cable.

Well, I just recently changed to CAT-6 cable from I believe an older cable the fat one CAT-3 I think. The reason why I change it basically is this, I thought the problem is my cable but unfortunately it is not.

And I have tried ping command on other PC and it have the same problem. I tried opening my router and I don't see any clue to upgrade the firmware and when I search it on google for my specific firmware update it show up nothing related to mine actually.

Maybe time to ask the ISP to help especially if this modem/router is owned by them. Since it does it from 2 different devices it almost has to be some issue with the router.

I tried asking them twice and to be honest they even don't know what's the problem is. I guess I just have to live with it.
Thank you for your response . Have a great day.
