Ping!

Recommended Posts

Well because I am not very tech minded I have'nt managed to post my PP graph!

But I have run PP the last couple of nights, and have a fairly stable line running at around 40ms but around every couple of minutes I get a ping spike up from 350-480 ms!

 

Anyone have any idea what could be causing this.

I tried bbc and Google uk as the targets and the ping spikes were the same.

There was no packet loss, and as I said it was a fairly stable graph except for those damn spikes

go to start, run and type cmd in the command prompt type    ping bbc.co.uk -n 25 that will ping bbc 25 times. change the number higher or lower to increase ping count.

just run it on wifi and there were less ping spikes, and not as frequent!

 

Just wondering if its the powerline adapters, they are about 5yrs old, could be the cables.

 

I will try it just connected to the Duma, via ethernet and not through the PL adapters

yeah. i did that a few times and the lowest was 15ms highest was 66ms average 17! and that was via wi-fi on the duma

If the spikes were a bit smaller then I would assume that it was the ISP hub causing it (it was for me), but 400ms is a pretty big spike.

 

When you're testing on PP, are you testing over ethernet?

If not, then do so.

Give it 10 mins and see if it spikes, if it does then disable the wifi on the Netduma and test for another 10mins and see...

 

That'll help determine if something connected to the wifi is causing it (if wifi is off then it can't obviously).

 

Also, you should try disconnecting your Netduma from your ISP hub/modem (so they can't communicate at all), then plug your ethernet straight into your ISP hub and run the test from there. If you still get the spikes on your hub/modem then you know that it's your line.

 

And it's worth running a continuous Ping from Command Prompt (Terminal on Mac), like BigDog said but without the 25 limit, just in case there is a bug with PP. I haven't seen this bug myself though.

Hi CB,

I have tested it on both, Ethernet and wi-fi, when it was on Ethernet that is when I had the very high spike,

Changed to wi-fi and the highest was around 70

Pinged bbc on cmd and it was 66 highest.

Currently running on Ethernet on PP

 

Will try the process of elimination!

Sorry, I didn't notice you say powerline adaptors either. *

Rule them out first, as Z and BD said, by direct ethernet cable from laptop to modem/hub.

What interval are you using on PP? Make sure it's the 2.5 second interval, 1 second makes mine spaz out sometimes.

 

* Maybe that's what my ex was saying about not listening to her, I can't be sure what she said though - it as boring so I wasn't listening.

just been testing on ethernet direct into the ISP hub, seem to be very little jitter, if I am reading it correctly

 

Are the spikes on the destination or on the trace in between.

 

Only the destination matters.

Thanks for all the advice guys... The Duma Army comes to the rescue again.

 

Just an after thought one of those plots was done via wi-fi so that would exclude the PLA as being FUBAR, or is the wi-fi unstable?

Yeah even if you have to snake a long cable around the home, it's definitely preferable to WiFi or PLAs. I liked the idea of PLAs and picked some up as they're really handy, and used a pair for around a year or so, but switching to a 15m run of Ethernet made the world of difference for stability.

 

Tldr: Zennon knows best lmao

Try testing through the ethernet going into your powerline adapter. To me it looks like it could be a bad adapter or a bad ethernet cable. Since you've tested directly to the ISP modem and it's fine that eliminates any ISP issues completely. The problem is somewhere in your setup.
