Broadband speed absolutely dire

[#1]

Oh I see what you mean, nothing that Im aware of.The only thing that happened about 1 week ago that was very unusual was that cable thieves stole copper cable from outside the telephone exchange a left thousands of us without phone and broadband but that was fixed last Monday.

Hi,
Yes that are the stats required - thank you, keep that link handy as we are likely to need to return to it from time to time.
Jelv's theory has verified that your current experience is indeed the same as last time and merging the threads ensures that anyone (especially CRT) do not see this event in isolation.  You can expect your internet to function reasonably well until the next cause is encountered and you are likely to get back here again.  Your line should be capable of doing better than it is now.  You stated previously that you are not overly technical - no not worry too much about that there is a great deal of help to be found here.
What I suspect is happening here is that something is happening on your service which causes a very slow connection to be established, that gets reported by BT to PlusNET (delta report) and applied to your line.  Your line improves, but the delta report might not...
- get sent to PlusNET by BT
- get applied correctly by PlusNET
- get picked up by your service via a PPP drop and re-establishment
The symptom of the last event was open of the first two above, today's was the last.  The real question to be explored / resolved is the reason for the slow speeds in the first place.
The SNRM is higher than expected, thereby reducing the potential synch speed.  The error counts look high.  The cause of these needs to be identified, the usual culprits are internal wiring, filters and the phone line itself.  There are out hers, but let's rule out the simple ones first.
Is there noise on the line?  Dial 17070 option 2 and recheck it from time to time.
How / where is the router connected to the phone line?
How many phones are there on the  line?  Do they all have micro filters?

When did you first notice the dire speeds - I ask because the actual cause of the low resync may have been BT sorting out the missing cable

[#4]

@Jim,
But your line is simply BAD!  It is though some comfort to lindap that theirs is better!  
The error counts could be distracting - I can never be sure which ones get cleared only by a power down.  The ones reported are not nice.
MAC is bad news, I was thinking that RouterStats might be an option.

Yesterday was the 1st time I noticed the poor speed and only because I wanted to watch something on iplayerand it wouldn't play at all. I don't tend to use the main computer which is a MAC unless we have to help with grandsons homework so mostly use an iPad instead and then only for email etc. Connection could have been poor for sometime without noticing.

[#6]

Not just my line but virtually all the lines from my cab to the exchange and there is no chance of them being replaced.
My point is that the low speeds may be a distraction from what causes the low sync event and that is what needs to be sorting

[#7]

I rather suspected that you had not really noticed periods of slow speed.
Can you provide answers as requested in reply #31 and may be we should ask CRT for a SNRM reset.

I have checked for noise doing 17070 - all ok
there are 3 phones Im going to unplug one of them, all have micro filters.
Router is connected in office at the rear of bungalow.
OK this is my plan
1. I’m going to regularly check for noise on the line doing the 17070 line test.
2. I’m going to change all the micro filters for new ones and check all connections.
3. There are 3 phones plugged into the phone line I am gong to remove one of them to see if that makes any difference.

Lindap,
Ah an interesting start point - is the the master socket or an extension?
If not the master socket are you able to try the router in the master socket?  Please post stats afterwards.
How comfortable are you about unscrewing the face plates and looking at the wires connected to the face plates?  There should only be two wires connected to pins 2 & 5.  Depending on the age of the installation, you might have a third wire connected to pin 3 - this is the bell wire and is unhelpful.  You can pull that one off and twist it out of the way.  This needs to be done at all of the sockets.
I like your plan (it is always good to have one of them  ::)) though dropping a phone off is not likely to have any impact unless the synch is dropping on inbound / outbound calls.  Being able to run router stats would have been very useful!

Hi Kevin
It is on an extension of the master socket, professionally installed by BT about 7 years ago.
I have no issues checking the wiring but will have to check it out later this afternoon.
I have a MAC .this is a download for Windows"......... "Can I suggest installing Routerstats (I assume you have a Windows Computer) http://www.vwlowen.co.uk/internet/files.htm ............I do have an old windows computer that I could connect and get some stats ........ will give that a go. 

[#11]

BRILLIANT!
Thought you said you were not very technical - this would really help.  Please post back on this thread when you need more help.
As for "professional" 7 years ago, engineers did not have in mind what is best for ADSL.  Sometimes what is adequate for phones is diabolical for ADSL.

@Townman
Can I suggest that we ask Plusnet for the following information as it could be very informative
Connection log
Date and time of the last few delta reports

[#13]

Jim,
That would certainly help profile the problem and indeed shine light into why the profile updates might not be being processed properly.
Detailed DLM history would also be useful too in looking at historic periods of slow synch.
Given that this issue has been intermittent and possibly on going for a while, it seems sensible to eliminate as much end user stuff as possible ready for a fault report, which might be inevitable.

Morning all,
After having a good review of the connection, it looks as though we have some pretty regular disconnections which I would presume are shifting the speeds around. The DLM doesn't seem to be changing much although the archive we have of these only cover the drop around the 25/09/14 which doesn't show an increase in errors so I would presume that this was a reaction to the drop on the connection around 17:30 on that day.
The SNR margins are currently set to 9.1 down and 6.1 up and Errored Seconds seem relatively clear. Can these disconnections be attributed to anything manual or is there something in the home which either turns on automatically or is activated manually that would tie in with the times of the drops we can see?
Here are connection logs for the last month to date in order to give a good view.

As for the Delta Reports, here is a view to match up roughly with the same month.

Adam,
Thank you for the detailed stuff.  Would you know what the date / time is on the delta data please, as generally they do not tie in with the radius plot.  Do they relate to...
The resynch which caused the change
The time BT sent them
The time PlusNET applied them - BUT did not drop PPP?
This user's history has the finger print of updates to the PN profile not generating a new PPP session.

Lindap,
The two events where you had sub 1k profiles needs closer examination.  It looks as though on the 5th at 10:00 there were multiple connection failures, resulting in a very low synch speed.
The 5 day period when there was no connection, where you away with the router powered off?
We really would benefit from being able to run router stats here!
Kevin
