When I first switched over to VDSL from ADSL2 I was supplied a HG633 this was working well except I was never happy with the WIFI performance on 5GHz.
Recently the HG633 started to make a high pitch audible noise I believe this was coil whine and started to really become a problem as it is located in the living room.
Internet speeds were stable and largly on the higher end of what what was expected and hardly dropped.
However more recently it did start around the same time as the whine it was getting after the recent contract renewal when we upgraded between 56-63MBps however lately it is strugling to get past 53MBps even after switching of for 30 minutes this didn't get better. I think this has caused the DLM to drop.
A while back we were also supplied a DSL-3782 which was only used when the HG633 had firmware problems before I was enrolled into the testing phase of the HG633 firmware before that was rolled out to all customers. I've started using this again two days ago however I woke up this morning to the biggest drop in some time down to 45MBps after a quick reboot this increased to 50MBps. The WIFI on the DSL-3782 is a huge improvement over the HG633 on 5GHz is much stronger and maintains a somewhat better max speed expected for the network bandwitch for dual band wifi, not perfect but a better result.
I know where to look for speeds which is always on the modem settings pages which is where I base all this knowledge from for speeds of the hardware.
So why at first was it at the maximum advertised and beyond expectations and more recently this has landed on the much lower end of advertised speeds? Fortunatly this is only £2.50 a month on the deal we were offered but when this goes up to £5 I can't justify the benefit of 5MBps for £5 a month so unless this is resolved when the time comes I will return to the old package at only a marginal speed difference.
This is what I always look for and not speedtest results.
I fully understand what I'm looking for with speeds, and because I can not change the DNS for this I can not get speedtest results that come close to what the link rate is showing it falls short by 4MBps down and 2MBps up.
I've now plugged this into the test socket ready for any testing that is required following what seems to be required when support is provided. I do hope this returns to the higher speeds that I had when we first enrolled to the extra fiber speed boost package.

Would you like me to pass this back over to our Network Team and request an engineer visit?
Have you recently tested with 2 different routers, cables and filters?

Apologies for this.
Just to confirm, has the connection remained stable?
An engineer would check/test the line for any faults. They would also test at the master socket and check the set up.

DLM will be monitoring the connection with this router connected.
Please can you post back on this thread in 48hrs and we can check the connection stats again.

Thanks for sending the update, I can now see the Noise Margin for Downstream. Will this noise margin improve further over the next 48 hours?

Thanks for the update. Our Network Team have advised that the next step would be to arrange an engineer visit. Would you prefer to test with the new router first before we arrange an engineer visit?

I've now ordered the WIFI Hub from the loyalty team, this should fix the WIFI problems mentioned. Got it for £30 after they credit the account back with £30 from the £60 that is initially charged from the loyalty team. Perhaps this might also get a more stable result which will also improve speeds. I'm thinking of also trying new cables inside the house to see if this helps.

Please see what can be done, I would like to understand what caused the speed to drop as drastically as it has in the last four months.
Downstream noise safety coefficient (dB) has increased drasitcally to since then.

Please see what they can do if anything, I would like to figure out / understand why the speed has dropped and the Downstream noise safety coefficient (dB) has increased from the low 3.6 it was four months ago.

Thanks for the update. I can ask our network team to take a look at this for you but your sync speed is within the predicted range for your line and above the guaranteed minimum so unfortunately there's probably little they can do
