Speed Issues

[#1]

@Dan_the_Van I would concur wholeheartedly with your attenuation comment - unless the line length is physically changed, those values should remain fairly constant.

[#2]

@jab1 

I was going to add there is like a high resistant joint somewhere, if not already I would connect the Hub directly to the master socket as internal wiring can also cause issue with the line attenuation. 

[#3]

Good call on the MS, @Dan_the_Van , although looking at the DSL  figures in the logs, I'm still inclined to be suspecting the OR external network. I could be wrong.

[#4]

Thanks - hub is on the only socket in the house - same one Sky router was plugged into for years

[#5]

@IJJ I suspect @Dan_the_Van  actually meant the test socket behind the master socket faceplate. Is your MS a single or dual-socket one?

[#6]

@jab1 single socket

[#7]

OK. I  would still suggest you tried the test socket, via a filter.

[#8]

@jab1 so I think it's an NTE5 type. Are you saying remove front plate and plug the filter into the socket behind the faceplate?

[#9]

@IJJ The NTE5 is the dual-socket type, can't remember the single socket designation. Yes, I am saying plug the filter into the test socket.

[#10]

@jab1 I think the dual is NTE5c but could be wrong - telecoms not my field. Further improvement when direct to the socket

[#11]

Interesting stuff can be found from event log files, the first DSL Link Up message is, this will be 2023

08:24:34, 22 Dec. DSL Link Up: Down Rate=32400kbps, Up Rate=10271kbps; SNR Margin Down=9.2dB, Up=6.4dB

The was the last time your connection synced to 40000kbps, this will be 2024

18:58:11, 28 Jan. DSL Link Up: Down Rate=40000kbps, Up Rate=12461kbps; SNR Margin Down=8.9dB, Up=6.1dB

The speed dropped 

10:14:46, 19 Feb. DSL Link Up: Down Rate=20388kbps, Up Rate=1127kbps; SNR Margin Down=6.2dB, Up=6.0dB

The fastest from that date was 

06:23:44, 13 Apr. DSL Link Up: Down Rate=32599kbps, Up Rate=864kbps; SNR Margin Down=2.7dB, Up=6.0dB

Now it is

15:18:05, 12 Jul. DSL Link Up: Down Rate=55898kbps, Up Rate=12092kbps; SNR Margin Down=3.3dB, Up=6.3dB

For DSL Link DOWN there has been 17 since first switch on - the previous to today's DSL link down as a result of the test was

05:23:01, 02 Jun. DSL Link Down: duration was 550370 seconds 

There have been a number of power off over the period which distorts the DSL connection time.

[#12]

@IJJ 
Are there any phone extension connected to the master socket, if unused suggest removing them

[#13]

@Dan_the_Van Not to the master that I can see. One line into the house that terminates at the master. There's a black box that runs from outside the house to the summer house but that is connected where the overhead cable meets the house. I think the previous owners had a second line for business.

[#14]

There is another improvement using the test socket,  if it is hidden out of sight I would leave the DSL filter connected to the test socket.

@jab1 

You are thinking of master socket 5c with a MK4 faceplate having the two ports.

[#15]

Yeah, there's a great big bookshelf in front of it....nearly gave myself a hernia shifting it 🤣

Thanks for all your help @jab1 @Marsh and @Dan_the_Van . I'll leave the filter in the master and keep an eye on it.
