Huge packet loss - Copper Broadband issues

I have been experiencing massive issues with packet loss over the past month and have reported my issue but been told that everything is fine. 

I have performed all the trouble shooting steps imagineble but after doing a ping test I can see hugh packet losses (attachement). This is really affecting everything that is using the network and making it hard to work from home and play any kind of online game.

 

An engineer did vist some months ago and confirmed that the speeds were slow and unsual but wasn't able to fix anything, pretty fruitful to be honest. 

 

What can I do to resolve this issue, or is it even my issue.

 

Cheers

Re: Huge packet loss - Copper Broadband issues

You're screenshot of the ping doesn't seem to be showing any issues as far as I can see.  Not all devices will respond to pings, and those that do will usually prioritise other workload over responding to pings.  The final hop, hop 9 isn't showing any packet loss, and the ping time to it isn't too bad.

What issues are you actually experiencing with your connection?

Edit: Just to reword that last sentence as it could be interpreted differently than how I meant it.  What I am meaning, is what issues are you seeing when using your connection that make you believe that there is an issue with it?

Re: Huge packet loss - Copper Broadband issues

I'm not seeing packet loss in your screenshot.

 

When you do a ping like that with a trace of all the intermediate hops, each ping request and reply packet has to pass through every hop in the chain.  Your image shows ZERO packet loss all the way and back for www.google.com, so the fact that the pings have reached their most distant destination without error shows that you don't have a problem.

 

Where your chart is showing packet loss in some of the intermediate hops, is just an indication that those servers don't treat ping requests to that specific device with any priority and are randomly discarded in favour of passing through actual important traffic - and is NOT an indication of dropping your traffic.

 

If one of the intermediate hops was causing real packet loss, then all the more distant hops would be showing accumulating loss figures because the faulty hop would be losing the ping requests/replies beyond it - so in your case the loss at google would be at least as big as the faulty hop.

 

To prove my point, you could setup a ThinkBroadband Broadband Quality Monitor to chart your connection packet loss 24/7.

In your Plusnet Hub2 you will need to enable ping requests/replies on the WAN connection.

Ideally if you want to use the BQM long term, then you should get a Plusnet static address, but if you just want to chart your connection over the short term then any chart you create will work until your router re-syncs and potentially changing your dynamic address - at which point the BQM will show 100% packet loss (all red).

Assuming you have a Plusnet Hub2, the problems you are experiencing are MUCH more likely to be associated with bufferbloat.

You can test your setup for bufferbloat using this test - https://www.waveform.com/tools/bufferbloat 

Checking your "Bufferbloat Grade", you'll want an "A" for gaming, a "B" for work video calls, or "C" for general use.

If you're getting worse than a "C" or need to achieve a better grade (for work or gaming), then the only real solution is to get a different router with anti-bufferbloat capabilities as explained in the "Frequently Asked Question" section under the test results.

 

Hope that helps

Re: Huge packet loss - Copper Broadband issues

Thanks for the replied and advice. 

 

I did the bufferbloat test and it came in at an F. The strange thing is that no new devices have been added to the network in months. I will go through the process of elimination and see what might be causing the issue.

Yikes ! - that indicates some ping responses > 400ms,  that would mess up your gaming etc !

 

Consider checking whether there is anything you can improve regarding your landline and DSL wiring, an "F" grade might indicate that your UPLOAD sync rate is being impacted by low frequency interference (associated with analogue phones).

  • Use a filtered faceplate on the BT Master Socket
  • Use the shortest possible DSL cable between the BT Master Socket and your modem/router
  • Is there any internal phone extension wiring that can be removed ?
  • Does the modem's upload sync speed improve if you unplug any phones ?
  • Are there any electronic devices along the route of the landline cable that might cause interference ?
  • Check whether your upload speed is 'banded' at an artificially low speed (as a result of a burst of noise or power cut)

Re: Huge packet loss - Copper Broadband issues

I performed more tests and I'm still getting an F. To be clear, I've only started to experience these issues in the last few weeks and nothing new has been introduced into the house or any new devices.

 

What I did before running the test:

  • Removed all electircal devices from around the Hub 
  • Singualr short cable was used to connect the hub to the master socket
  • Disconnected all devices connected to the hub

https://www.waveform.com/tools/bufferbloat?test-id=3a210c72-7e57-4618-9a76-ff04586ee908

 

I'm not sure what more I can do now. I need Plusnet to come out and check it but they won't send an engineer.

Re: Huge packet loss - Copper Broadband issues

Can you post a screenshot of your Hub's DSL stats, showing actual and attainable line rates, SNR margin, etc - BUT hiding your username.

 

Can you also post a screenshot from the BT Broadband Availability Checker  showing the two lines "VDSL Range A (Clean)" and "VDSL Range B (Impacted)", but being careful not to show your phone number or address.

Re: Huge packet loss - Copper Broadband issues

BT test attached.

I searched through the HUB settings and I think I've found the stats you asked for.

Re: Huge packet loss - Copper Broadband issues

It would be useful to have visibility of what BT Openreach thinks your up and down "IP Profile" numbers are.

 

First find the BBEU number for your connection,

    it should be displayed in your Plusnet 'Member Centre' > "Manage Account"

 

Go to - BT Wholesale Broadband Performance Test , and hit the "GO" button

when the test completes, hit the <Additional Diagnostic>

click on <Broadband Service ID (BBEU)>

enter your BBEU number in the box below

then hit <Run Diagnostic> and wait ... .... ...... ........

 

IF that completes successfully (for some people it doesn't) ,  can you post a screenshot of the results.
