Jitter


BENORMOUS

Recommended Posts

Thought I would re-post here as it seemed more appropriate.


 


Apologies for the delay  - I only managed to run the ping plotter pro last night.


 


Can someone have a look at the attachments and please advise?


 


Attachment 1 - tested to 8.8.8.8.the jitter reads 0.43 which looks good but at hops 3 and 4 it shoots up in red.


Attachment 2 - tested to twitter - jitter is showing 0ms (Great) but hops 2,3 and 4 again large spikes.


Attachment 3 - tested to pingplotter - ping is 120 ms! Hope this was a one off as other ping results have been low. 


 


My question is: Should I be concerned with the jitter spikes in pics 1&2 & the ping increase in pic 3 and if so should I report it to my ISP, or just pay attention to the round trip results which look ok?


 


Thanks Guys

Only worry about the destination ping and jitter if its 18 at the destination (there and back) so the last reading then all is good and it is just the hop not responding to ping for a moment this is normal as servers are set to do this under stress.

Hi guys, 
 
I have a similar problem. Often times I have bad spikes and bad jitter via the Netduma internet diagnosis tool. When I get bad values the pingplotter recordings stay the same. My jitter is also not good on the pingplotter program. 
I called my ISP and they said everything is fine. They did some testing and finetuning and that's all. 
 
I know jitter should be very low. In general it is on 5-10 ms. 

The pingplotter test stats on a different Laptop connected to the ISP modem via ethernet cable are the same as via the Netduma R1. 
 
One year ago I got a new line through the wall from my ISP because of other problems. 
 
What can I do about it?

Do you mean I can confront them with my stats that show I have bad jitter? 

 

This image was taken 15 min ago. At peak times the R1 says that jitter and spikes are bad (red color). 

 

Yes if you get enough conclusive proof of the jitter on your line you can take it to them - they may not do anything but are more likely when confronted with proof.

 

Do some tests over peak and non peak times, if its like that during peak times then as Zennon said it's ISP congestion

You may need to tell them to 'escalate' the issue because sometimes the first contact does not really have a technical background.  Or atleast it is this way with Comcast.

Yes by all means keep a folder of your results.I did it 3 times a day for 2 weeks and it showed I had severe node overload on certain nodes.

 

Then I called my ISP and got them out here to look at my findings,which in my case did no good as you need a tier 1 tech or a line supervisor.But what you will get is a tier 3 guy that only knows from pole to house and if your getting 80% of the speeds your promised,then he'll say everything looks fine on their end.

 

But don't let that be the end of the story,be persistent and ask to speak to a tier 1 or line super and show them your results,weather it be node overload or what ever is causing your issue and hopefully it will get addressed.

  • 3 weeks later...

Hi again guys,

 

I did some testing for the past 3 weeks and also a tech-guy from the isp came to my flat to check everything. With my netduma I got consistant lag spikes to 500 ms and higher. Without it using just the isp modem with upnp I got an avarage of 25 ms. A hard reset of my netduma didnt work. Did it 6 times in total. The last 5 days without the netduma where really nice without any bad ping spikes using the pingplotter program on pc and mobile phone. When I plug in the R1 the problems start again. I put the R1 allready in the box back. So my question is what should I do now? I got a product that cant perform the general purpose of a simple router. Bevore somebody suggest that i read the manual ... Lets skip this.

Tried it in bridge mode and in normal isp router/modem mode. With the r1 the spikes and jitter get real.

 

Did you experience simple problems? Do I have a faulty R1? What advice can a tech guy from the forum give me?

 

Cheers and I hope to get some help here.

Can you double check this http://wiki.netduma.com/doku.php?id=why_do_i_have_insanely_high_pingsas it can cause high pings and is a very simple issue. Are these game pings or just general pinging? 

 

Are you using congestion control when this occurs?

Hi Fraser, 

 

thx for the reply. This was the first thing I did. The cables are fine and I have 6-7 different cables at home. They are connected properly. I did my tests with them. 

I used CC and this occured in games and also the pinggraph is really bad when I use pingplotter. At first I thought that it's the ISP modems fault (UBEE evw3226) but I did my tests with it also. The pinggraphs get bad when the R1 is connected to the Ubee modem in bridge mode and in normal mode of the modem. In both cases my connection drops very much. The netduma internet test show also very bad spikes and jitter (terrible). 

 

When the modem works alone, not connected to the R1, then my pings and spikes are very good. I don't have such high pings or spikes ingame (Evolve 500+ ms) or via pingplotter as with the R1. I really don't understand what the problem is. 

 

I'll buy a TP link router and connect it to my isp's modem to see if I'll get such high pings. If not, then it's definitely the R1 fault. 

 

During the peak-hours, only using the isp modem, the spikes get from 20ms to +/- 40ms. Using the R1 during the peak-hours the spikes get to over 400-500 ms!

 

As I mentioned I did a hard reset about 6-7 times in total. 

 

I have some gameplays WITHOUT the netduma in the first few days of the release of BO3: 

 

They were better than ever :(

Okay can you PM me please and we can set up a 1 on 1

 

Thx Fraser but I think I'm gonna send my R1 back to you guys. 

 

I did a hard reset again and made some tests with and without the R1.

It might not actually by the Netduma cause in those results, the modem test and Netduma test were taken an hour apart from each other (I think as that is what the times show). This is easily enough time to be on/off peak time and be caught in ISP connection. I think what would be best is if once you've seen the bad results on the Netduma, connect to your modem and see if you get the same thing. Also remember to stop other devices using the internet on the Netduma when doing the tests as you did for the tests on the modem.

Crossy I can show you the last 2 weeks of my recordings. On some days I did 12hour+ recordings in all kinds of combos. With R1 without and so on. The ISP modem does not have this kind of peak time spikes in any recording what so ever. Only the R1 does. It's normal that the ping slighly go up on peak times but not to 400 or 1900 ms as the R1 does. 

 

Every test I do is via lan cable and I plug of other devices so only the laptop is connected! I also did tests directly to the modem via lan cable. That are my bests results yet. And I think I can recite the Netduma Wiki now. 

Anyway I'll print out every recording I have and send it with the R1 to the warranty department. There is no doubt on my side that the R1 is faulty because since May 2015 I use the R1 and the ISP modem together. And now the R1 does not work right. 

 

I also think advices like "Have you tried turning it off and on again?" are needless because I did this easy stuff 100 times. I have reached a point where I feel that I am not taken seriously. 

 

Hmmm...
