So i've checked my distance: 1.01km
My phone line is clear.
Master socket: No difference.
SY1 2DL to SHREWSBURY exchange.
I've checked my modems stats:
Quote Uptime: 0 days, 6:19:59

I'm really disappointed with the down-rate I am receiving?..
Plusnet site statistic:
Quote Postcode:
Phone exchange:
SHREWSBURY
Estimated line speed:
8Mb (This may vary between 6.5Mb and 14Mb) - Checked on 2013-06-07 18:03:05
Current line speed:
21 Mb
No, my current line speed is not 21mb, it should be up between 10-15.

57 thousand in 6 hours? - ugh
Your attenuation is also high for a 1 Km line
I'm 2.2Km from the exchange and that is an accurate "as the cable runs" figure and my D/S attenuation is 35
I'd agree though for a 38 attenuation line around 10 to 12 would sound about right for a 'normal' line - dependent on quality as usual.
Something is seriously wrong with your line
Are you running from the master test socket?

Quote from: x47c It's the errors on the line I'd suspect.

It is quite high, it also should of been running longer than that, as I've had it on since Friday, but haven't been present at the computer until yesterday.
I am indeed running from the Master Socket, and also tested with the test-socket by opening the panel. Still same issue.
Think my profile is not updating as it should, or, my line is faulty.
However, phone line seems clear.

If you run the BT speedtest then further diagnostics what is the IP profile

Your sync speed is 4058 which is way too low
If you think it should have been on for longer than 6 hours that points to disconnections happening on the line requiring multiple re-sync's
On 21CN Exchange equipment it should work as follows:
Sync speed *0.883 = BT IP profile
This is set automatically at re-sync time
Plusnet profile then aligns itself with the BT setting rounded down after a bit (usually a day or so)
So for example a BT profile of 14.39 would become a plusnet one of 14.3.
Your problem is that your sync is only 4058, but as to why...............
Maybe the line has become banded (restricted) due to previous or still ongoing instabilities
Do you have any stored data from when it was known to be working properely. Sadly it is always difficult what with the variability of phone lines to know where one should be starting from when trying to get a handle on what is happening now.
Over to Plusnet methinks - they will probably advise running the faults checker now that you have been using the master socket.

Quote from: x47c No idea why your plusnet line speed is saying 21Mbps
Because that is the default at start-up and it hasn't managed to drop yet? We have not heard from Lightning1 since 2010 prior to this thread. I presume there has been some change in circumstances and he/she is now in the 10-day training period.

We'd be happy to chase this for you if you could post up a ticket ID? Unfortunately your forum login is linked to an old destroyed account and we'd need to look at the current one

Will do this once I am back from work..

Couldn't create a new account - it's using the same e-mail as last time. It refuses to let me create a new forum account link with the new account , as this profile is still active and related.

Quote from: Matt I understand that, I was asking because it's not possible for us to find your broadband account at the moment - if you could post a ticket ID we'll be able to find it and offer more help that way.

Can you describe what you have and, if possible, provide a picture of the wires attached to the removable part of the test socket
