High Latency / Timeout packets

Hi all,

been having some issues with my line over the last week. Have left it in the hope that it would resolve itself but that doesn't seem to be the case.

I'm having issues whereby the latency on my PC will spike and/or drop a packet which makes online gaming almost impossible. The spikes are happening every few minutes or so.

Here is an output from running a Ping test from the HUB itself.

And here is an output from CMD

Really struggling to find what the issue is here. I've already:

- Verified it is not just the PC and multiple devices are being affected

- Tried a different cable to ensure that is not the issue (PC side running through a powerline adapter)

- Run a test on the line itself where no faults were found

- Tested ping from the HUB itself which also returns high ping

 

If there's no faults on the line, is it possible it is the hub?

Any ideas appreciated

Re: High Latency / Timeout packets

The only accurate way to test is to use a  direct connection using a Cat 5E/6 cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook and no other items connected.

Firstly set up a BQM at thinkbroadband.com - this will give you an insight into what is happening with the signal coming into the property, it will take a few hours to get any kind of trend showing.

Post a link to your BQM on here.

then

Type 192.168.0.1 into your browser URL bar and press enter.  When the page appears DO NOT LOG IN but click ‘Check Router Status’. Copy and paste the contents of each tab onto here, a Guru will be along soon to decipher the info.

Re: High Latency / Timeout packets

Appreciate the response. Tests are below.

So the BQM seems to be fine but I guess that depends how this polls the data. Is it a 1 minute poll interval or is it realtime? issue if it's 1 minute is these spikes only last 5-10 seconds and therefore it's possible they are missed.

Re: High Latency / Timeout packets

PLEASE NOTE: The red on the BQM is where I took the internet down in the hope a off and on again would fix it but still no luck

It pings every second 1000ms and plots the graph every 100 pings.

Re: High Latency / Timeout packets

Thank you for your post Harrybaker and sorry to hear of you current broadband issues.

 

Could we please ask that you run a speed test on the PC and post it in your response so that we can see the results? 

 

Can we please also confirm that you've tried an alternative ethernet port on the back of the Hub? 

Have you also put through a pin hole reset on the Hub?

 

Let us know, Emily.
