Very poor line performance (again)

cjedonline — Fri, 18 Oct 2024 18:57:18 GMT

Hi, could you reset my line back to a reasonable speed please. Over the last few months (since July) it's been getting slower and slower. It's now way below my "Guaranteed" Speed.

Here's the current DSL status from my router :

Line Statistics

Downstream Upstream

Actual Rate 30000 Kbps 11999 Kbps

Attainable Rate 57916 Kbps 22708 Kbps

Path Mode Fast Fast

Interleave Depth 1 1

Actual PSD 7. 7 dB 11. 2 dB

Near End Far End

Trellis ON ON

Bitswap ON OFF

ReTx 0 1

SNR Margin 13 dB 16 dB

Attenuation 19 dB 26 dB

Here's the corresponding figures from July :

Line Statistics

Downstream Upstream

Actual Rate 53430 Kbps 19269 Kbps

Attainable Rate 59426 Kbps 19270 Kbps

Path Mode Fast Fast

It looks like noise on the line has increased and DLM has adjusted your connection downwards accordingly. Have you noticed any issues with your voice service? Have you tried switching the router off for a full 30 minutes to reset the session? And tried connecting at the test socket?

Subject to that, the support team will pick this up when they are back online from Monday.

No, there's no noticeable noise on the voice line (although it doesn't get much use) . I'll try switching off the router for 30 minutes, but in my experience, line training only works in one direction, a reduction of speed.

Hi @cjedonline

Apologies for the delay.

How's the connection been since the 30 minute power down of the router?

Hi Debbie, I turned the router off for 4 hours or so on Saturday. It made no difference.

However, this morning things are even worse!

Downstream Upstream
Actual Rate 20690 Kbps 11999 Kbps
Attainable Rate 43325 Kbps 19519 Kbps

Hi @cjedonline

Thanks for your reply.

I've completed a line test and this is detecting a potential fault.

Is the router currently connected at test socket? Once I've confirmed this then I can raise this over to Openreach to be investigated.

Thanks

Debbie

Yup, connected to test socket - improved slightly :

Line Statistics

	Downstream	Upstream
Actual Rate	30000	Kbps	11999	Kbps
Attainable Rate	57979	Kbps	19977	Kbps

Hi @cjedonline

Have you just moved to the test socket? (today)

Re: Very poor line performance (again)

cjedonline — Mon, 21 Oct 2024 11:35:25 GMT

Yes, that's correct. I have tried it previously (with no change in connection speed), but it's quite inconvenient to have the router connected there (it's on an outside wall), so normally it's on an Openreach installed socket the other side of the room.

One of our line tests is failing and showing a possible issue with the copper section of the line.

I've logged this out to Openreach to take a look.

Thanks

Karl.

Thanks, any idea when that might be ?

As this is a non appointed engineer, should be within the next 24hrs.

Thanks

Karl.

OK, following Openreach doing something this afternoon, the line is back to "Normal" performance :

Line Statistics

	Downstream	Upstream
Actual Rate	53998	Kbps	19985	Kbps
Attainable Rate	59232	Kbps	19985	Kbps

Thanks for sorting this out.
