When I first received fibre broadband (March 2017), I was receiving download speeds up to approx 28-30mb. A wireless speed test I did in November came back at 26.2 down/7.95 up.
Last week, having attempted to download the BO4 beta coming in at 30+gb I noticed my speed was not as I expected and that I was only connected approx 20mb download.
I have since powered off the router (left for over a min), then also powered off and left for over 30mins. Currently, as per the router admin page, these are my connection stats:
The support team here will gladly look into this for you. It will help if you can check and confirm that these speeds are the same when connected at the test socket. And whether you have an alternative router to test with. Finally, as a precaution, if you can also test for any background noise on the landline.
1) Another router > I don't have another I can test. Just the HG633 provided when I joined.
2) Test socket results (not really much different). I don't have anything else connected to the socket, extensions etc and it's quite a new socket:
I'm sorry to hear this and I'll take a look into this for you now. I've run a test on the line which hasn't detected a fault. Just to confirm, how long has the router been connected at the test socket for as it can take between 24-48hrs for DLM to make changes to the speed if the connection remains stable?
Ok thanks for confirming this. Could you bump your thread (request an update) tomorrow and we can re-check the connection stats to see if DLM has started to increase the sync speed?
Connection is just as it was in my last post when I reconnected it to the master socket. DSL Connection up for 2 days 42 mins.
What next? Can DLM be reset? Understand you might be able to do that remotely these days?
Thanks for the update. I've re-checked the connection stats and I can see that DLM has increased the sync speed since my last post. How have you found the connection? Have you noticed any improvements?
We had a power cut on Saturday at 11pm and it then reconnected at 25.6mb.
So did that have anything to do with DLM or just the fact the connection reset itself after the power cut?
I did also make a call on Sat morning and the line was crackling a bit. I don't use the phone that often, so will try keep an eye on that.
If the speed increased straight after this then it may have been due to the power cut. Noise/crackling on the line can affect the broadband connection.
Is the noise permanent or intermittent?
As we hardly use the phone, it's not easy to say but we're going to keep an eye on it.
Still connected at the same speed since the power cut Sat at 11pm, stats as below:
But we need your help to fix it. Let’s talk about it via Live Chat.
Between 'Our Network' and 'Your home'.
So what test is it doing that's bringing back that result.
At the moment, every time I've reset the router, speed has gone up slightly, rather than DLM seemingly doing anything by itself, why is that happening?
We hardly use the phone, so hard to say, but we'll keep an eye on it and feed back.
Line connected the same as it was on Saturday at 11pm after the power cut:
I've completed a line test which hasn't detected any faults but I can see re connections on the line. Your line is also in sync at 25.6mb.
Are you experiencing any drops in connection? Is the router at the test socket?
I've re-checked the connection stats and the connection looks stable for almost 4 days and the sync speed is within the predicted speed range. How have you found the connection over the last few days?
The connection seems pretty stable. I've tried a couple of different micro filters just to see that made a difference and not really.
So the only disconnections have been me swapping those over.
Current connection stats in the test socket still:
DLM can lower the line rate and copper section of lines can degrade over time, but DLM will choose the best profile to balance speed with stability. As long as the speed remains within the predicted range for the line then the system is behaving as it should.

Beware of being fobbed off by TalkTalk technical department on the Chat line. My problem is a speed reduction caused by a noisy line. This was explained to me by a BT Openreach engineer when I had the same problem a while ago.
This is how it goes: Noise on the line causes a drop in speed as it is trying to compensate for the interference. When the noise disappears or is cleared up the speed remains slow as it will not automatically reset. It has to be reset to its optimum value by (probably) BT Openreach.
The TalkTalk "technical" department only have a limited knowledge of this problem and will go through their standard procedure of sending a new router (unnecessary).
When I try to explain this to the technical department they do not listen. Neither do they refer back to historical data. I don't blame them really. They have limited knowledge and limited resources. They just have written procedures and the ability to keep on sending out new routers.
You're relatively lucky. My download speed has been consistently 27-29 Mbps for about a year until it dropped to 9 Mbps about a week ago.
I know what the problem is and how it can be rectified but TT won't listen to what I have to say. All their "technical" team have is written procedures which they have to rigidly follow.
I had the same problem about a year ago.
The cause of the problem is noise on the line from dirty contacts on the BT master socket. This manifested itself by hearing crackling on the telephone. The noise causes the speed to drop to compensate.
The noise was removed by sliding the plug in and out of the socket. However the drop in speed remains and has to be reset back to its optimum value.
I'm not sure if the reset has to be done by TalkTalk or BT but I'm guessing it's BT as TT are reluctant to reset the speed (as it would cost them to call a BT Openreach engineer).
The above cause and solution was explained to me by a BT Openreach engineer.
The bad news is that TT will not listen to me and their solution (as always) is to send out another router. I now refuse to accept another router as it is a waste of time.
