Dramatically slow broadband. Possible congestion issues?

Hi,

I am a recent (11 day) customer on BT Superfast Fibre. For the first few days, I didn't notice any issues with our broadband connection (download speeds anywhere from 32-50mbps, as advertised). Mid-way through last week, I noticed dramatically low download speeds of less than 1mbps during peak times. This seemed to resolve overnight/in the morning, but returns around 7pm during the week. Noticed it again at the weekend, variably.

 

I spoke with BT support, who thought it may be a loose wire somewhere. However, that doesn't really seem to fit, as power-cycling the router improves things temporarily, and then speeds drop again after about 10 minutes. Same is true for factory reset, or if I use a VPN. I wonder if this could be due to congestion at peak times.

 

An engineer visit is booked for Friday, however I am reading a few similar stories on these forums stating that the engineer couldn't help.

 

This is my BT wholesale speedtest from this evening - download speed 0.16mbps and ping latency over 6000ms. 12 08 19 at 1924.png

 

This is my exchange/cabinet information.

For all ADSL and WBC Fibre to the Cabinet (VDSL or G.fast) services, the stable line rate will be determined during the first 10 days of service usage.
This line is on a Market B Exchange.
For VDSL or G.fast Ranges A and B, the term "Clean" relates to a line which is free from any wiring issues (e.g. Bridge Taps) and/or Copper line conditions, and the term "Impacted" relates to a line which may have wiring issues (e.g. Bridge Taps) and/or Copper line conditions.
In order to be eligible for handback, downstream speed should be less than Downstream Handback Threshold values.
Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises.
The Stop Sale date for Datastream is from 30-Jun-2012; the Formal Retirement date for Datastream is from 30-Jun-2014. The Stop Sale date for IPstream is from 30-Nov-2012; the Formal Retirement date for IPstream is from 30-Jun-2014.
If the End User wishes to migrate from their current Broadband supplier they will need to contact the Broadband supplier they want to take service from to arrange for the service to be migrated.
Please note that postcode and address check results are indicative only. Most accurate results can be obtained from a telephone number, NAD, UPRN or Access Line ID (ALID) check.
Note: If you decide to place an order for a WBC fibre product, an appointment may be required for an engineer to visit the end user's premises to supply the service.
Thank you for your interest.

 

Wonder if anything can be done to help?

 

Thanks,

Johan

Re: Dramatically slow broadband. Possible congestion issues?

That looks more like a line problem rather than congestion 

Have you checked for line noise  dial 17070 option 2  should be silent and best with corded phone 

Have you tried using test socket with filter to see if that helps

Post hub stats advanced setting then technical log information

Re: Dramatically slow broadband. Possible congestion issues?

Hi,

 

Thanks for the reply. I don't have a phone to test for line noise, unfortunately!

 

I have tried the test socket with the filter, and I didn't get a broadband connection through there? I had asked the first engineer (who installed the line) to move our wall box to where I wanted devices with a wired connection (TV, media box), so maybe the first box is disconnected?

 

Below is the log information. It seemed that I lost just before 19.00.

Re: Dramatically slow broadband. Possible congestion issues?

I should note that connection seems to be working fine again, for now! It's just so dramatically variable.

Re: Dramatically slow broadband. Possible congestion issues?

Sorry that is the logs it is the heading information that provides the stats 

The most basic tool to test your broadband is a phone to  check you have a dial tone and if so is there any noise  this should be done from test socket  this test can save you the engineer call out fee of £85

Re: Dramatically slow broadband. Possible congestion issues?

The one place where your broadband should work is the test socket so if no internet there then there is something wrong with your wiring and needs investigated

again testing line for noise is needed

Thanks for the advice, will get a phone to test the line and see what things are like the next time speeds drop.

Re: Dramatically slow broadband. Possible congestion issues?

Hi,

 

Update today, connection down again at the same time (just after 7pm).

 

Did a line test with a corded phone while the connection is down, there is a dial tone, and no sound on the quiet line test. This was on the secondary box that was placed during the initial install.

 

Definitely no dial tone at all from the test line on the primary box at any time - when things are working or not.

Below is the log from the router (taken while connection was down):

I'd disconnected my router briefly when checking the test line at the primary box, and again, on re-connect, everything works for a few minutes, before a switch seems to flip and the download speed drops to 1mpbs and ping latency is 1000ms.

 

Thanks,

Johan
