@Anotherone It has been a long time for myself, as an engineer in the merchant navy I used to do vibration monitoring/analysis on motors/pumps etc so I have a few ideas on what might be causing the problem. At the moment though this is all moot as I have had a reply from PN fault team and they have washed their hands of the problem

We have tested your line and have been unable to identify issues outside of normal parameters on the line. I do note that your records are showing some errors on the line, but as these are not exhibiting on the exchange equipment. This makes me believe that the errors on your logs are showing error rates pre-correction. If these minor errors seen are able to be corrected by the equipment, then they will not be having any effect on your service. I note that you are asking for a REIN engineer to investigate further, however we need for the line to be exhibiting line errors and/or significant drops on the line for our suppliers to be able to investigate, and we are seeing "green" parameters on your line across the board.

I'm not surprised their equipment isn't showing anything, my SNRM is set high to suppress these errors and interleaving is on. As to these errors not affecting my service, I'd consider a 20-25% reduction in speed a considerable effect.
I'm really annoyed that a REIN engineer will not be called out. At the moment PN are quite happy to give me sub standard service while allowing the law to be broken.

Can you post the current DSL stats and I've give a more detailed reply and suggestions later on.

New adsl filtered faceplate for the NTE5 box arrived yesterday so that is fitted, plus the firmware has been updated to 10.2.2.B

Leaving the Plusnet agent's response aside for a moment, BTw's specs are wide enough  to drive a bus through sideways and even when they've accepted a fault, it can take several SFI engineer & Boost engineer visits, even when the evidence is fairly obvious, before BTw might even consider a REIN engineer - there aren't exactly too many of them.
Which Filtered Faceplate did you get in the end?
Have the fans been running during those 5 hours of uptime on the stats?

I'm not exactly impressed with the Openreach attitude to such issues:

[#7]

@w23 thanks for the info but as usual openreach are full of bs, on that link you put up :

Quote

Unfortunately there is no current legislation that allows us or the telecommunications regulator (OFCOM) to take action against such faulty equipment.

and yet on this link :http://www.conformance.co.uk/adirectives/doku.php?id=emc

Quote

In the UK the Directive is enforced by the Trading Standards Service and Ofcom. Penalties for non-compliance can include three months imprisonment and a £5000 fine but generally involves a recall and replacement of the affected product.

So how can they claim there's no legislation when a £5000 fine or 3 months imprisonment seems like an enforceable legislation to me

[#8]

Yes, something doesn't really seem to add up.

[#9]

This is typical Openreach prevarication to try and avoid having to send out REIN engineers which can be a costly business for them.
@gtowen
When the fans aren't running (ie when your SNRM in not being reduced by the Interference) during the day, can you do a PPP Disconnect and power down for 10 minutes. Power up and don't forget to login and click Connect.
This will give us a completely clean slate of stats so we can see exactly what beneficial effects the filtered plate is having - limited evidence from the modem/router so far suggests it's helping rather. I wouldn't place too much significance on those average stats you posted for the time being, as I indicated previously the figures can vary somewhat, depending on how and when certain errors occurred and I've also found the  figures don't always seem to relate directly to the actual errors.

[#10]

ok, one fan is running atm, but I'm not getting any FEC errors, so I disconnected the PPP for 10 mins and then took these stats.

With just the one fan running, maybe I've narrowed the problem even further, but only a REIN engineer can prove it.
I'm also wondering if I should request an SRNM reset, at the moment its fixed at 12db

[#11]

Yes you may have narrowed it if things change when the other fan starts up.
However, just dropping the PPP sessions doesn't reset any of the stats figures. The point of dropping PPP first, is that with no active session when you power off the modem/router, DLM sees it as user action, not a random drop of sync. I would not recommend doing it whilst any fans are running, if there is noise being generated and picked up at present, it will result in reduced achievable sync speed (nor anywhere near dawn or dusk or after dark - noise levels will be higher).
An SNRM reset is something to go for WHEN you are sure you have more stable conditions which you certainly can't be at present. You can't get a fault raised to BTw whilst a line is in training, this will limit your options, especially if things got worse.

[#12]

How close can you actually get to either of these extract fans?  You might be able to pick up interference directly with the AM radio, also the AM radio is 'directional', if you turn it so that the ferrite rod inside is pointing towards the source the noise should disappear, at right-angles it should be maximum, do this from a couple of different positions and you might be able to 'pinpoint' the source (though this method may be rather 'hit and miss' depending on what else the radio picks up).

[#13]

@w23 In Reply#65 I posted photos of the fans, fan2.jpg shows the positiom of both fans. The one on the right I can stand underneath and is off atm, the other due to property restrictions I can get to about 7m away. That one is running but I'm getting no FEC errors so I'm assuming the one on the right is the problem. Then again I'm confused myself atm, last few days I've had errors starting from lunch time, today I'm getting nothing, so not sure if it is the fans or something else. I'll just have to watch the FEC errors and when they start check to see if the other fan has started.

[#14]

Totally confused.com this morning . All last night I monitored the FEC errors and apart from a few spikes the graph was steady at zero. Even weirder when I went outside BOTH fans were running. The only thing I could see on my stats was that SNRM was as high as 14db.
This morning I disconnected the PPP @ 09:45 hrs. Switched off the router @ 10:00hrs and then went out for the sunday papers. Switched the router back on 10:25hrs and took these stats ;

From these stats you can see SNRM has dropped back to 12db, my sync speed has gone up to just under 13Mb/s and my BTw ip profile has gone up to 11.39 Mb/s.
So got no idea what is going on :(. Maybe if I'm lucky the mysterious noise offender has blown itself up and won't cause anymore problems....... shouldn't have watched the new Oz film last night.... no ruby slippers here.

[#15]

Oh well, so much for wishful thinking   Whatever is causing the interference was switched on again about 17:30hrs.  FEC errors gone thru the roof again and SNRM dropped and I can't blame the fans this time It really needs a REIN engineer with specialized equipment to track this down.
