Disruptive disconnections, speed dropping

[Pale91]

Hi there, I'd like to open this up to the community cause you guys have been amazing with help in the past!

I don't have fibre broadband yet, it's still ADSL. Every year there are new faults, new problems, and I pretty much have to trial and error stuff to remedy it.

Starting a couple months ago, broadband disconnects, struggles to reconnect (sits flashing purple for 5 mins) and then struggles to regain speed. Overnight, it dropped 10mbps. I'm aware that speed tests are not affirmation of a fault, however, they are a fairly reliable indicator that something has changed.

It then began disconnecting every single day, with the same symptoms afterwards. This issue is replicated on 2 different routers. It's wifi AND ethernet wired.

Two engineers have been out. Firstly a Cube engineer who said he can see disruptions, but no issues with home set up. Then an Openreach engineer, who moved a branch off the line and said 'try that.' Of course, the issues persist!

I was hoping that someone could please take a look at the last disconnection, and see if there's anything odd in the event log? https://imgur.com/a/y5ExJed

I work from home, so as you can imagine these unpredictable and random disconnections are very annoying during calls and work.

Thanks so much for any help. Below are the hub stats:

@Pale91 

you are on fibre to the street cab and copper to your home so FTTC not ADSL

is there any noise on your line  assuming you dont have digital voice can you dial 17070 option 2  should be silent and best with corded phone

your noise margin at 2.6db is very low and probably not helping maintain connection

[Keith_Beddoe]

You are on FTTC not ADSL. ADSL comes from the exchange with speeds of below 20mbs and upload speeds about 1mbs.

[Pale91]

Okay, thank you for the correction. I get confused with the copper wires part! I just know it's not fibre or whatever.

Noise test sounds about the same as it always has, nothing obvious standing out there! Cube engineer checked it too.

Thank you!

[Pale91]

Does anything look odd about the disconnection? I can find others if necessary!

Thanks for your time. Getting desperate!

@imjolly 

Does everything else look normal?

What can I do about the noise margin being too low? Noise test sounds same as usual I think, cube engineer checked that too. 

Thanks for the info! 

[imjolly]

when you say noise sounds 'same as always' there should be no sounds on quiet line test it should as the name suggests 'quiet'  any noise is a problem for your connection

has your connection dropped since yesterday?

[Pale91]

Yes, it has disconnected twice since then. The latest one a couple minutes ago. It disconnected when the house phone rang, the exact same time. A quick disconnect and the Data Rate on the homehub Information has once again changed. It's very inconsistent, it changes every time there's a disconnect. Fluctuating between 38mbps and 55mpbs. That's the Data Rate, not a speed test. Speed test varies wildly.

Noise margin has also changed. It's all very inconsistent, fluctuating per disconnect. Please have a look at the changes:

I'm tearing my hair out over this, it's very frustrating. My line has issues every year, and every year BT and the support tries to convince me it's anything BUT a fault on the line. They tell me it's probably ''radio interference'', or my heating coming on (it's off) or wireless interference (I'm wired) or a busy line (in a village). Anything and everything but a fault.

The Openreach engineer suggested there's probably corrosion on the line - but there's nothing I personally can do with that information. I can pass it on, but won't be believed. What is my next step here? What does ''DSL Link Down: duration was 325503 seconds'' mean? Does that not suggest the problem is elsewhere, rather than in my home? Is there anything within the event log that points to a cause? 😓

If anyone has the time, patience and kindness.. my profile has info dating back years, from previous desperate attempts at a reliable connection! This current problem has been happening for months:

Huge thanks for your time.

If an Openreach engineer suggested what the fault was then he should have resolved it. That's his job!

Report the fault again.

[Pale91]

I hear you on that...

That'll be the third day off work for an engineer. I simply can't afford to keep doing it. Especially since it's entirely hit or miss, and I'll get the same script that it's caused by me. Or by the router (I've tried two as previously mentioned). Or aliens even. Anything but a fault! I guess I just have to keep trying until I get an engineer that's competent?!

Assuming that nothing stands out to you on the event log? Just looks like a ''normal'' disconnect? I'm not sure how to read it. Trying to pinpoint ANYTHING.

Thanks so much for replying.
