I'm having the same problem as before. That is the every time the DLM kicks in it raises the s/n ratio and drops the sync speed.
Engineers have been out twice and got the speed back up to 36Mb. The last engineer left his mobile number and said to give him ring if it happened again.
I rang him and he checked the data for the last couple of weeks since he was here. He informed me that Talk Talk have capped my line at 25Mb. I was surprised on hearing this.
He said if I can arrange to get him out again he may be able to do a proper fix by getting extra help and thoroughly checking out the D-side of the line and if necessary changing the pair. A different engineer would just do a reset which would not get to the cause of problem.
Like I said, I was surprised on hearing Talk Talk had capped my line without notifying me. I can see how they would think this was a poor workaround for a bad line, but I'd rather have it fixed properly.
DLM changed your profile in the early hours of this morning - sync speed is now 33.1Mbps. I'm not sure what the engineer means when he says that we've capped the line, the line is managed by BT Openreach's line management system (DLM), this makes any changes to your profile, that's why the 25Mbps cap is removed when the engineer resets DLM
I saw the change, but I don't beleieve it will stay there. I think it will just keep recurring as it has been.
Before the sync change it was 24.9Mb and the s/n ratio was 11 with high interleaving. The engineer said yesterday that there had been few errors for the last two days.
I'd still like to take up the engineers offer to cure the problem.
I'm sorry but we would really need the speed to drop again before logging over to our network team. If you let us know if the speed drops again we can log it over for investigation and potential engineer visit
Thanks for the update. If the sync speed improves, however there is no increase in throughput speed then we usually advise switching the router off for a full 30 minutes as this will reset the current session. If their is no improvement following this then we can look into this further for you.
I switched off the router on Friday, but it didn't make any difference, download speed was still 25Mb. Sync was 36Mb.
Did the same on Sunday and it worked. Sync is 32Mb and download speed is 30Mb.
So that appears to be okay at the moment. I will continue to monitor.
I'm sorry to hear this and I'll take a look now. I've run a test on the line which has detected a potential fault towards the property and the connection also looks unstable.
Are you experiencing any issues with the voice service at the moment? Is the router still connected to the test socket? As soon as we've confirmed this then we can pass this straight over to our Network Team.
If you can verify as soon as you can, that would be great. We can then log the fault correctly.
Either way, it will require an engineer, so as soon as you have tested, also reply to the PM I'm going to send you so we can get the usual engineer booking red tape out of the way.
