Slow internet speed

I have been having slow download speeds over the last week or so.

 

Previously it was around 7Mbps, now it is at less than 1Mbps. I have swapped over the microfilter and changed the DSL cable to see if the speed improves. It did not improve.

 

Upload speed is normal at around 1Mbps.

 

Can you assist?

Re: Slow internet speed

@abc123  If you would like help from the community, a good starting point is to have a look at This post and supply as much detail from it as possible.Sight of the HelpDesk page, under the Troubleshooting tab on your router homepage - with personal information redacted - is very useful.


It would also be a good idea to carry out a 'Quiet Line Test' - dial 17070 from a (preferably corded) phone and select option 2 - there should be no discernable noise. If there is, report a phone fault first, as without a clear phone connection, your broadband will not perform correctly.

It may be an idea to also report your lines capabilities - please post your results from THIS site, but ensure your phone number is obscured/hidden.

If you reply to this topic with as much detail as possible, there are plenty of experienced members who can advise on possible remedies.

If you decide to also post on the Twitter/Facebook accounts and get a response from there, please come back here and say so.

Hello @abc123

Thanks a lot for providing me with the details, just seen your PM.

Anyway, tests on your line appear to show that there's a loop fault on the phone side of things. Please contact your phone line provider and ask them to run some checks on the line, they should be able to identify it. Smiley

Re: Slow internet speed

@adam945 

 

As suggested, I contacted BT with the informaiton you provided below regarding the loop fault.

The OPENREACH engineer visited and advised that a cable in the box outside my property had corroded. This caused a DLM cap on the line (to 1Mbps max) and it is the reason for the recent slow download speeds.

The corroded cable has now been replaced the download speeds has been restored.

The DLM cap is normal for this type of issue.

 

Thank you for your assistance with this.
