Issues with connection

Hi, last month i upgraded from ADSL to FTTC, and my connection has been dropping daily until it seems to be settled at the following:

Data Rate
45858 kbps

MAX Rate
86460 kbps

SNR Margin
7.3 dB
6.0 dB

Line Attenuation
13.9 dB
0.1 dB

Path Mode
Interleaved

Interleave Depth
1713
227

The checker says i should be able to get 80meg and i'm about 600m from the cabinet, following the road, so i was wondering if anyone knows if i could have an issue with my line, and if so, what to do about it? My connection used to drop a fair bit on ADSL too, but i never lost speed due to it.

Thanks for any advice.

Is the router connected to the master socket? If so, remove the front plate (if it has one) and connect directly to the test socket via a microfilter (this is located behind the front plate). See if the issue stops, if it does, then it's a problem with your wiring. If it still continues, contact your ISP.

Hi, thanks William. I did connect it to the master socket behind the plate, and also did a quiet line test from the phone, and noticed a slight hiss in the background, so i phoned the ISP and he ran a test.
Apparently there is a fault.. something to do with copper joints.. not sure what that means, but he's raised an issue with engineer.

One joint is displaying either HR (high resistance) or semi-conductive tendencies.

Ah right. There's a very old GPO junction box in the house where the line comes in, could it be that, and if so, would the engineer be able to tell / come in and fix it ?

A HR (or semi-conductive) joint can form where two dissimilar metals are joined in the presence of moisture. It would, most likely, be found somewhere in the outside plant . . . either in a jointing chamber or an aerial joint.

Just because there is an "old" junction box within your premises does not necessarily make it the prime suspect. A competent technician would be able to trace the fault, given enough time. If s/he needs to enter your premises, I'm sure that the junction box will be inspected.

Appreciate the responses - very informative.

You are welcome.

Hi, my line was sorted apparently, got the DLM reset and all was good for a couple of days, but today i've noticed Interleaving has been turned on and dropped sync speed again. I didn't have any disconnects either.
I'd like to replace the box joining the drop wire to the internal phone line wire - What would you recommend i swap it with?

Can you post a picture of the box please?

You'll have to upload an image to a photo sharing website, e.g. https://imgur.com and post a link to it here

. . . both externally and internally.

Of course.

Well its clean and dry at least .

Not really 'yours' to play with though.

I'd replace with gel crimps in an empty BT80 myself.

Unless you are worried about aesthetics, I would just leave the box where it is but take out the screws and use a couple of jelly crimps to join the wires.

Alright.

How come the incoming wires that are in use look silver, but the ones in the yellow skin look copper?

They're all copper but the ones that look silver are "tinned"

tinned

adjective
adjective: tinned

1.
British
(of food) preserved in a can.
"tinned fruit"
2.
covered or coated in tin or a tin alloy.
"a pair of tinned copper conductors"

Trouble is, the lid won�t go back on if you crimp it ....

I see no problem. And please note the words of Zarjaz.

Replaced. Made no difference. But it looks nicer which helps with OCD i spose ;P

Over this weekend i've been having SNR going all over the place and my attenuation and errors have skyrocketed.. see pic:

Router Stats

4meg Sync ...

What could cause this?

Short of suggesting to try another modem, as the DSL-AC68U with its default offered settings is relatively unstable without G.INP it seems, those stats look very odd. For example, the U0 attenuation is very wrong. Some kind of line or wiring fault I feel would be the cause.
