Hi, Since yesterday evening I've started getting lots of dropped connections - if I'm lucky a connection will stay up for maybe an hour, if not less than a minute. I guess about 10 mins is typical at the moment. I spoke to the support line and they said my line was fine, though the phone line sounds crackly to me. I notice that in my router stats, noise margin is all over the place fluctuating between 0db and about 10db (downstream). Line attenuation is fairly constant around 21db, though I have seen spikes up to 47db (downstream again). Connection speed varies a lot too, between about 4kbps and 9kbps downstream. Previously I would have expected around 11kbps. Why might these figures be shining about so much and might they explain the frequent dropped connections? Noise Margin seems lower than usual, that may have an effect? I noticed today that the line from the telegraph pole to our house looks a bit frayed (edit: see attachment), could that be causing a problem? Thanks, Steve

Hi there,
I've just been running tests on your line and they also pass too, however if you're still hearing noise on the line it might be a good idea to see if you can borrow another phone handset just to rule out if its the phone causing that to happen.
With regards to speeds it will be affected due to the disconnections so we'll need to focus on that, broadband diagnostics don't reveal anything obvious but I'd try following the advice here next https://goo.gl/tu2WWu do keep us posted.

Thanks for the reply.
I have replaced the microfilter and the cable that connects it to the modem. The connection seems stabler now, and noise margin is now up to around 20-25db, though upstream it is still only 7db (why the mismatch?). Connection speed is well down still, though, 2.2k.
Line attenuation is 20-30db down, 6.5db up - again is it odd that there is a big difference?
I will keep an eye on things!

If you're still hearing noise on the line, it's so much easier to raise a voice fault, which should resolve the underlying issue. Joints can go bad, trees can damage wires, etc.
Most phone lines were never designed to carry anything other than voice, so xDSL speed is on a "reasonable efforts" basis. But get the metallic path working right for voice and you'll generally get the best result for xDSL.

Hi there.
I'm just following up here. Your connection doesn't look too good over the past few days.
I'm testing your line and I'll reply over to the ticket on your account shortly.

Thanks, I hope so too
Connection has been a bit more stable the last 12 hours or so... snail's pace though. I'm not entirely convinced that the rain doesn't make it worse.

It's been my experience that several engineer visits might be required to resolve audible noise -- especially if intermittent

Hello @sca1
We can see that the connection is still dropping and are monitoring it until after the next engineer visit.

Damaged drop wire from pole to house replaced, line sounds much better now, noise stats looking healthier too, so fingers crossed speed will pick up soon

Awesome. It might be worth asking PN to force a DLM reset

Glad to hear that @sca1
And a DLM reset has now been done. You should see improved speeds within 5-10 minutes.

Brilliant, 16M down now, and that's before FTTC is switched on
