Something wrong
I'm afraid I didn't get a new corded phone.
The filters are just the standard ones supplied by Plusnet with the TG582n router. I also have two old TalkTalk ones.
I have a standard NTE5 main socket, router is connected to a single extension socket. Apart from corded phone there is no other connected equipment. Usually use laptop connected by wireless. This always seems reliable even with router wireless on low power.
About this switching off - I know the usual claim about keeping router switched on, but I am never really happy leaving equipment on overnight. I always switched my router off overnight and this was so in the past even when everything worked perfectly with speeds over 16Mbps. I have tried leaving it on continuously for some days but I never noticed it made it run faster. Could it not be equally argued that leaving it on all the time increases the probability of it picking up a noisy episode and so slowing down?
I have only needed to do several restarts recently due to much reduced speed at start up or several disconnections. When things are going OK, normal switching on/off does not seem to cause any problem.
What has been happening recently is the SN margin diving all over the place from +14dB to -2dB! In the past the SN margin on Plusnet used to start at 6.0dB at switch on and was a straight line for the whole day, that is when I got +16Mbps. It is currently 15,836kbps, 5.9dB. It has been fairly stable today.
I am keeping an eye (and an ear) on a very slight noise at the phone connector plug when mechanically disturbed. The sockets do not seem to be noisy.

How do you know? Also, the point you miss is that this is a highly intermittent problem.
<i>I dont know a lot about this stuff and this may sound harsh but you appear to be doing everything wrong.</i>
But like you said you "dont know a lot about this stuff".
<i>You appear to have a poor phone on which calls you receive are noisy?
You say "
Noise: There is a problem with a noisy hook switch on my phone, this would only be apparent on incoming calls or checks for messages, it wouldn't be a cause of problems when phone was on hook. I have experienced intermittent noise on incoming calls and cannot be entirely sure whether this is on the line or from the hook switch, but some noises lately have been fizzing noises which don't sound like the sort of thing that would be caused by the switch."</i>
So how do you know the origin of the noise? Let us all in on your 'secret powers'. The latest disconnection has occurred while my landline phone was deliberately disconnected.
<i>You are using wifi instead of a wired connection. </i>
Yep! It's legal where I live.
<i>You have the router on an Extension?
Is that a proper BT extension or a cheap flat wire plugin telephone extension cable.</i>
It is a normally installed wired extension. It comes with the property.
<i>When you take the front off the Master socket are there any wires attached to it? (on the inside)</i>
Well, I'd be in trouble if there weren't! Do I need to ask for my last years Plusnet subscription to be returned?
<i>If it is a BT extension what wires are connected (colours)
You keep switching the router off despite all indications that it will be better left on.</i>
I keep HAVING TO either switch it off to hard reboot it, or soft reboot it over my wireless(!) connection from my PC.
<i>"I have tried leaving it on continuously for some days but I never noticed it made it run faster."
Leaving it on is not a quick fix - it is agradual improvement in line quality as "seen" by the system.</i>
Oh really? So what do we do while we are waiting?
Contrary to what you say, my experience is if it starts up with a low speed rebooting it DOES achieve a more normal speed.
<i>" Could it not be equally argued that leaving it on all the time increases the probability of it picking up a noisy episode and so slowing down? "
Not really if there is external line noise from a skybox/TV/ railway /electric fence/ intruder alarm/ street lights (list is endless) it will be picked up whether the router is switched on or not.</i>
Really? You mean like my TV receives BBC programmes when it is switched off? Also - if it makes "no diference" then switching it off doesn't actually matter, does it?
<i>You seem to be running Router Stats but you dont post the stats as requested so we cant build up a picture of what is going on.

I am not currently running "Routerstats".
All useful information gratefully received. I'm afraid, cedlor, that appears to exclude you.

Very often with Broadband problems, there can be one (perhaps small) issue that only occurs very intermittently and it's only when another problem arises, or maybe even a 3rd that a user complains about a problem. It's then, that one has to go through a process of elimination to get problems resolved.
Reading through the thread to try and see what potential issues have either been addressed or eliminated, reply #35 is fairly typical of responses in this thread, I ask for some information and my question in the previous post is completely ignored and that post a couple of weeks later just goes on about how your connection has dropped. reply #44 is another where you didn't make one single response to any of the points mentioned in my previous post and you come up with some pie in the sky idea that your wifi is affected by some exchange issue!
Right, I'll eliminate some of the points raised.
With your relatively short line, switching off at night and considering the time of day when you tend to switch on (based on the VR graph) would in normal circumstances have little effect on performance of your connection. However, when you have a dropping connection it can sometimes make a difference, I wouldn't have thought it would have at present, but can't be certain.
Rebooting repeatedly (last Thursday as an example) without doing it gracefully as previously mentioned, especially if errors are high and the connection is dropping, will sooner or later cause DLM to act which it appears to have done. Earlier this year it banded your speed.
Graceful disconnects you have admitted you stopped doing.
Your most recent problems appear to have got worse around the same time you bought a new TV, so there has to be a suspicion that there maybe an issue with it causing interference. You don't seem to appreciate that any number of electrical and electronic devices can cause interference when they are either faulty or badly designed. A dealer may not be able to adequately test whether or not your TV is causing an issue in your setup up (with whatever else you have connected as well). Looking what's happening to the SNRM and errors whilst running RouterStats is the only way of checking this out, and any device being checked must be unplugged from the mains, not just put into standby to be sure.
Edit: Deleted remark due to confusion with another user
Using a "wired" connection eliminates any potential interference to a wifi signal as well as helping to demonstrate consistency with some of the test results which may help eliminate or point a finger at any potential modem/router problems. A users interpretation of logs or stats does not provide adequate assurances about anything. Trying to get real data and facts from you is like trying to get blood from a stone!
Those remarks and your total lack of response to some of my posts shows that you do not understand the complexities that can be involved.
I tell you what, you certainly have a phone line fault, albeit intermittent, and that could be difficult to resolve, but I suggest you concentrate on that first as that seems to be the predominant problem and has been going on since January at least.. I have other commitments next week so I won't be wasting my time on what appears to be a fruitless exercise trying to help you. I have written many posts on this forum that will explain to you how to go about checking your internal wiring and that the extension is wired to the correct standard for broadband, and how to deal with potentially dirty connections with plugs, sockets and filters. It could be any of those causing your problem. Just because "it came with the property" means nothing. I suggest you go and have a long read.
Once you are certain that any noise is in fact on the external line, then Report a phone line fault using the Phone Troubleshooter (login needed). You need to do all the checks ultimately at the test socket to protect yourself from any potential charges.
If you are lucky that a line test reveals a fault at the time, or an engineer visit locates one, then should you have any remaining problem that maybe related to interference, you could read my many posts about those problems as well.
I'll briefly comment on the stats you've just posted, in a minute.
