When we first got fibre broadband about 2 years ago the download speed was about 34 Mbps. It was this speed for at least the first year, but over the last six months or so I have noticed the speed has gradually been reducing. It's now less than 24 Mbps. (I am using an ethernet connection to the router, not wifi.)
Although this is not critical, it is still a lot less than it was initially and disappointingly not much faster than the non-fibre broadband we had before.
I have tried resetting the router by leaving it off for 20 minutes and then restarting (as advised previously by a TalkTalk representative) but this has had no effect.
Please can you advise what may be causing this.

Done. The download speed is now 36 Mbps - so back up to what it should be again. I think that has solved it. Many thanks for your assistance. I shall know where to come should we have the same kind of problem in the future.

Apologies, sometimes the line engineer will attend at the property once they have completed testing on the line.
Please can you power down the router for a full 30 minutes to see if the throughput speed increases following this?

Thanks for the updates. The Openreach engineers were here at 9am this morning!
They reset the DLM and the router sync speed is now back up to 38 Mbps. However, the download speed at the computers is only 19 Mbps (using ethernet) so they said that there is a further issue for you to investigate, possibly a problem with the router?

Our Network Team have now advised that a BT Openreach line engineer is already investigating this fault and we should receive further updates within the next 24hrs.

Thanks for the Private Message.
I've passed your availability for an engineer visit over to our Network Team and I will post back on this thread as soon as I receive further information.

I've sent you a Personal Message to confirm some details in order to arrange an engineer visit.
Please do not post any personal information on the Community, reply via Personal Message (PM) only.

This line test can be completed straight away once I know the router is at the test socket.
If you would like to go ahead and arrange the engineer visit then please can you reply to my Personal Message.

That was the configuration over the weekend, the router and both phones were connected through one filter into the test socket.
When you say run another line test, is that an instantaneous test or does the router need to be left at the test socket for another 48 hours?
I have disconnected the upstairs phone to see if that makes any difference, but assuming in 2 days there is no change to the sync speed I will then be happy to go ahead with an engineer visit.

Thanks for your reply.
If the router was connected at the test socket then this would rule out anything connected to any extension sockets.
Would it be possible to connect the phone, router and filter at the test socket so we can run another line test in this set up?

You asked in a previous post if there was any other equipment connected to the line. There are two telephones, one cordless and another old phone on an upstairs extension. Do you think one of them is likely to be causing a problem? Is it worth ensuring that they aren't the problem before we get an engineer to visit? It is difficult to do without a home phone because we use it all the time, but I could disconnect the upstairs phone, and/or possibly change the cordless for another model.

I've checked the connection stats and I can see that the sync speed hasn't increased, apologies for this.
I've escalated this fault over to our Network Team for investigation and I will post back on this thread as soon as I receive further information.

"Is the fact that the router has been turned off and turned on later a few times (moving the router to the test socket and back, there was also a power cut this week) affecting it because DLM thinks these are errors and reduces the sync speed?"
Yes this can affect the sync speed as DLM will change the profile to help stabilise the connection.
I've checked the connection stats and I can see that the line is in sync at 20mb. Please can you leave the router at the master socket for 48hrs (over the weekend) without rebooting the router? We can then check the connection stats again on Monday. If the speed hasn't increased then we can raise this over to our Network Team for further investigation.

I notice that the router restarted at 6.30am this morning. Is this DLM operating? The sync speed is now 20 Mbps, the slowest it's ever been. Is the fact that the router has been turned off and turned on later a few times (moving the router to the test socket and back, there was also a power cut this week) affecting it because DLM thinks these are errors and reduces the sync speed?
The router is no longer connected at the test socket, I can't leave it there unfortunately. But I have proved that at its current position makes no difference to the connection speed.
Can DLM be reset or restarted for my line?
on 18-01-2019 09:02 AM
Thanks for the update. It can take between 24-48hrs for DLM to make changes to the sync speed if the connection remains stable. Is the router still connected at the test socket at the moment?

I have now connected the router to the test socket, but this has made no difference to the connection speed. I have not used an extension cable in this set up and have disconnected all other equipment on the line. The sync speed is showing just 22 Mbps. This is even slower than it was six months ago.
I can probably leave it like this for a few hours, but will need to revert to the normal configuration where this router is on an extension socket, as I have a computer that only has ethernet. If you need it left in the test socket for 48 hours (as Debbie mentioned in a previous post) I will have to work out a time to do this.

Unfortunately we're not here at the weekend. Did you notice any increase in sync speed whilst the router was connected at the test socket? Is the router usually located on an extension socket? Do you have any other equipment connected to the line?
