MOD Help Needed: Changing NGA Profile to Speed

ReeceHands — Tue, 30 Jun 2020 20:11:33 GMT

Hi all,

I've been having problems with high ping spikes over the past year and I'd like to get my NGA profile changed from standard to speed.

This is the an example of the ping jumps I have encountered in the past;

The connection varies, with mornings being more stable and then the connection jumping constantly. We've had a line test and there was negligible noise on the line. Everything is wired, nothing is wireless. I've contacted BT in the past and we've had resets, master socket replaced but we still have these ping issues. I'm hoping someone on the forums knows of a way to fix these?

I'm thinking it has something to do with interleaving?

Hi @ReeceHands welcome to the forum and thanks for posting. Sorry that you are experiencing ping spikes.

Interleaving can only be changed on ADSL broadband connections.
Are you using the BT Hub?
Can you run and post a ping plotter when you are gaming only with no other devices connected?

Cheers

John

Hi John,

That ping plotter was when I was the only person using a device in the house.

This has been happening on and off for quite some time, I am on a BT Hub

As you are on fibre connection the latency is controlled automatically by the DLM there is no manual intervention as you can with adsl

Hi Jolly,

Is there anything that could be done about the dlm?

I keep having these horrible spikes of 100ms or more.

As I said the DLM is automatic and no manual intervention unlike adsl

probably look at your setup and see if you can improve connection from hub to devices

We've changed the cabling, master socket has been replaced - I'm not sure what else to do

This is a ping test ran 04/07 - 00:12

It's not really an acceptable level of ping jumps. Could someone advise if there is a problem with my line?

Hi @ReeceHands,

Thank you for posting back. To get an idea of how your connection is performing please can you post your router stats? Please can you run a Ping Plotter as well, this will help to give us an indication of where the latency is occurring?

In your first post, you said there is "negligible noise on the line. Any noise on the line no matter how small has the potential to affect the broadband connection.

Can you try the quiet line test? You can do this by dialing 17070. You will reach BT's line test facility. Choose option 2. The line should be silent.

Thanks

PaddyB

Hi Paddy,

Sorry, I should have been more clear. There was no noise on the line when last tested, however I'm getting these spikes at random. I've just come back from being away for two days and this is my current stats as of 20:20

I'm having no problems with upload or download speed I have been having ping issues since the start of this year.

Just to add, I cannot do a test on my end as we do not have a BT phone package, just the line.

if you have a BT Broadband package then you need a phone line to get the broadband and that is part of your package. So you should be able to dial 17070 and check quiet line and run tests

You've linked to a screenshot of the wrong page from the hub. You need to go to advanced settings/technical log/information.

Can you upload the screenshot here instead of linking to another site. Just use the camera icon.

Hi Pippin,

Please see my information log,
I'm still getting similar jumps in ping.

Re: MOD Help Needed: Changing NGA Profile to Speed

I'll also send one around lunchtime tomorrow to check line noise.

Re: MOD Help Needed: Changing NGA Profile to Speed

ReeceHands — Fri, 10 Jul 2020 13:09:35 GMT

Checked this afternoon and line attenuation is still the same.

I've done some research and we're only around 0.7 - 0.8 of a mile from the exchange, and from what I understand line attenuation of 42 db is quite high considering?

have you done the quiet line test? just because it was fine last time it was done does not mean it is ok now

enter your phone number and post results remember delete number see if estimated speed range is what you would expect from your estimated 0.7/8 of mile

Hi Jolly,

BT sent out a new hub which has changed the line attenuation stats. Connection was stable for a day before high ping spikes began again.

Ping test from today (Apologies, the file was too big to upload) https://puu.sh/G6lf7/a938d07550.png

Pictures below;

Test as requestedBT sent a new hub out and these are the stats

Connection speed is within your expected range and noise margin is about normal 6db

looks like older firmware so probably get a reset in next couple of days as hub gets a firmware update

Re: MOD Help Needed: Changing NGA Profile to SpeeD

ReeceHands — Tue, 14 Jul 2020 16:09:19 GMT

Hi Jolly,

Will this firmware update happen automatically?

I'll keep the thread updated
