Thanks for pointing that out, I did look rather quickly, just picking on the words proto parser! But as it's another failed connection attempt you can't deny that it makes it look like there's something wrong, nor can you ignore what mushroommrs is saying.
As I said earlier, you could make your posts a little more constructive, or are you in one of those moods today where you are just looking through my posts to find something you can pick holes in. I'm not perfect, I get the odd thing wrong, you make it sound as though everything else I've said is catastrophically wrong. But then you never make mistakes.
@mushroonmrs
Try those ping tests again when his iPad is switched off, in fact make sure everything is off except the computer you are running the test on. Apple stuff is well know for constantly connecting and updating and this might be hogging the modem/router and connection.

OK. I don't think we are going to glean anything further that's going to be useful, so a modem/router and filter swap would be a good idea.
Now one thing I didn't mention in my previous post about swapping things, is because you are on a very long line, it will be subject to quite a bit of interference after dark due to AM/MW propagation. This will reduce the SNRM and any resync will then be at a slower speed. So change it and the filter if you have a spare, in daylight, a good hour after sunrise and a good hour before sunset.
Then post the new modem/router stats and some ping results
Edit: Is that Belkin a v1, v2 or v3?
I will try and do it tomorrow pm. Too busy in the morning unless by some miracle I am up at six. Have a funeral to attend on Friday, so won't post anything until Saturday probably. Don't need a filter. Not sure which version it is, that info is not on the box but I have had it about four years so maybe a v1. Re after dark interference - perhaps there are vampires about.....

Can you hear any crackling or other strange noises when you use the phone? Use the Quiet Line Test 17070 option 2 if need be.
Hopefully one the CRT can run a Copper Line Test for you to see if there is any obvious fault showing at the moment.
The line will go down for about 3 minutes if they do, any you speeds will be slightly different afterwards. So if it changes, post some new stats.

The estimates are 0.75 to 2.5
With a 63.5db attenuation that's pretty much the highest that a lot of routers will report.

Quiet line test just sounds like an open line.
I know the estimate is 0.75 to 2.5 but until recently I have always had around 1.16 unless there has been a problem.

Now, although I take Chris's point on board, I was going by a previously achieved sync speed from the Delta reports that Chris provided which suggested that your line might/did achieve a sync (Data rate on your
However, it would help significantly to know if that was the case, then we can stop being concerned about something still being wrong.
As far as the recent speed tests go, that last one being a bit slower, might just be normal variability, such results can vary from test to test and a one off value cannot be relied upon. TBH, you want to forget speed throughput results for now, as it's the sync speed and profile that are the important things. Throughput speed will follow the profile (usually just below it).
Now, if you are not tweaking the SNRM, it could be that the
Bearing in mind you are on a 20CN connection, this unfortunately means that if you have a lower sync speed which drops your profile to the next band down, it does so immediately and even if you then achieve a slightly faster sync speed that would put you into the next profile band up,. it's only a small change and can take 5 days for DLM to up the profile (and then your Plusnet Current Line speed (Login required) has to catch up which may also not happen immediately. So stability at a sensible speed is imperative. A sync speed of 1440 or just above would give you a 1.25Mbps profile after a of stable connection with no drops.
So really we need to know the following 1) Are you tweaking the SNRM? 2) Is the SNRM changing somewhat during daylight hours? - it will drop some between dusk and dawn. 3) Is the sync speed (data rate) remaining stable or is the connection dropping?
Edit: correct modem/router brand to that which OP referred

The SNRM should be fairly steady during daylight, but would be expected to go up and down as dusk approaches, after dark and until after dawn.
Post back if you see the data rate change and what the SNRM is doing in daylight (an hour after sunrise upto an hour before sunset).
Do a few random Quiet Line Tests to see if you can hear any crackly noises at any time, but also make a point of checking it if you see significant changes to the SNRM in daylight hours.

noise margin started at 4.5 around 09.30am - it has changed up and down all day, starting at 3.4 at midday 3.3 at 1.00pm 3.5 at 1.30, 3.1 at 2.00, down to 2.8 at 15.09pm.
found an old set of stats from the same Belkin modem (2011) 1728/448 5.2/13 16.7/12.3 63.3/31.5

Don't forget to keep trying Quiet Line Tests.
Failing that, now your initial results with the TG582n suggests it has a problem, but I'm not going to simply give up on that as being faulty hardware. The symptoms could just as easily be caused by Firmware corruption, so if nothing else, I'm thinking maybe on Monday (when the right staff are in), to put the 582n back on and ask Plusnet to push the upgraded firmware 10.2.2.B to it, and then we can see if it performs any better.
I'll try and get back to you later on monitoring with the Belkin, unless anyone else comes back sooner.
Edit: Just to double check - did you ever try changing the filter? (Don't do it now btw)
