No master socket in the loft, the incoming drop wire goes into a small white connector approx. 2" by 2", the phone cable comes from this to the first socket in the upstairs front bedroom, this is where the router is connected now. It is a different router and filter.
There doesn't seem to be the amount of errors as before but the sync rate is even lower and the attenuation has jumped up to 80. Had to reboot a few times which wont have helped matters.

Time to do the Fault Checker now i think. I had a look inside this socket and there are so many wires connected i wouldn't know where to start checking.
The incoming one and two hard wired extensions with what looks like every wire connected.

Blue+white trace on 2, White+blue trace on 5, Orange+white trace on 3, White +orange trace on 4, and if a 3rd pair is present Green+white trace & White+green trace on 1&6.
If you have cable with solid colours Orange, Blue, Green and Brown that will need to be replaced in due course. There's also the "bell wire" issue to deal with.
I don't think your wiring has caused this fault, this is looking like an exchange fault but you'll have to run the Fault Checker and get a fault moving. Two modem/routers reporting similar stupid figures is confirmation of a fault.
Can you hear any crackling or other noises on the phone line?
Have you had any thunder and lightning recently?

No noise on phone line, 17070 quiet line test, line silent. no thunder and lighting recently. This seemed to start when i plugged in this external HDD that i think had a faulty power supply. I've completed the Faults Checker so will see what this shows up.
@ejs Telephone seems OK, has a dial tone and a clear line.
Thanks again
Ron

If it's the wiring that's faulty i have sort of resigned myself to having to pay to get this sorted.
Thanks to both of you for your help and advice. Will update the thread when i get it sorted.

After over 30 years it's done rather well really, he reconnected the one extension socket that was required and all is back to normal. I must say he was very helpful and obliging. Stats are better now than they were before.

This is after approx: 4hrs uptime.
Plusnet profile is still at 0.03 Mb. will this update automatically or can plusnet manually fix this?
Once again thanks for all help and advice

Did he replace the cable to the NTE5 or have you still got the old junk there? Is the extension just for phone - and so is filtered if he fitted a vDSL plate?

Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps
Cable not replaced to the NTE5, the extension is just for cordless phone downstairs and the base unit is fitted with a filter to the phone socket.
He tested phone before he left and all seems to be working ok.

Did he fit one of these or one of these ? I guess the box in the loft looks like this
Is it a difficult cable run from the loft to the Master?

The box in the loft looks exactly like that one. I don't think it would be that difficult to run, it's about 5mtrs of cable from the small box in the loft, down through the ceiling , down the edge of the door facing into the Master Socket. Would this improve the connection as it seems ok now? I thought that anything up to the Master Socket was BT's responsibility and should not be altered.

It really depends on how your connection performs.
The old standard of wiring will pick up interference, how much depends on your locale, I wouldn't be able to predict. This could result in slower speeds (after a few drops in connection). As the master socket hasn't got the vDSL plate, the extension wiring may contribute something as well and would be best replaced - that bit is your responsibility not BT.
If you wanted to have a go after you see what things are like I can suggest where to get the CW1308 cable (39 p/m P&P £1 and a small tool to push the cable into the IDC terminals 99p), and give you connection instructions.
Alternatively, if you see a local BT man working, you could try asking him if he'd do it all for you for a tenner or so, tea and biscuits, cake etc!
