Speed loss after fault repaired

[odds]

Hi all,
Could someone with a bit of knowledge please shed some light as to how this can occur, I'll give some details now to help.

Earlier this year I was able to sync at anything between 6.5 and 7.1, I then lost both phone and BB connections, engineer called, fault at the cabinet, repaired that and lost half meg connection speed.
Then in August, same thing happened, only this time the fault was at the exchange, apparently someone had disconnected the wires and left them, that was sorted and once again half a meg lost in download speed.
I have tried explaining this to Sky ops but they just say "that is all your line is capable of" ........ but it wasn't before Openreach 'repaired' it on two occasions.
They have even manually configured it allegedly, and managed to get a little back, but surely it should just be exactly the same as before, after all they only connected a couple of wires back.
So my question is, what the hell do they do that keeps making the line characteristics change everytime they touch it ?

Thanks.

It might help to see a little more information before going into too much detail.

Could you take a look at the link below and post your connection stats please?

How to get your router statistics

Also can you describe how you are connecting your Sky router to the telephone line (i.e. on an extension, in the master socket, with the grey ADSL cable supplied with the router, with a Sky supplied microfilter or filtered faceplate)?

The router is connected to the test socket via a filter, internal wiring was checked on both visits and the fault was found to be external, so all I was wondering was how come the line never returns to it's original state after being 'repaired/reconnected' ?
Don't forget that they have said that my line will only work at this speed, when I know for a fact it has never been this low for the past 2 years at least, and when they suggest it may be because of more new customers at the exchange been connected then I think you know you are pretty much banging your head against a brick wall

My Stats are as below : Using a Netgear DGN1000

System Up Time 00:03:28
Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time

WLAN 11M/54M/150M 354 95 0 524 78 00:03:12


ADSL Link Downstream Upstream
Connection Speed 5469 Kbps 509 Kbps
Line Attenuation 39.6 dB 16.8 dB
Noise Margin 7.3 dB 16.8 dB

Thanks for looking.

I think you still have a fault in your external wiring. Getting it fixed properly will not be easy, although you should have about double the sync you have, it is not easy to get Sky's so called help to believe this.

I don't think the number on your exchange has anything to do with it. The number on the exchange would not effect the sync, only the actual throughput. Sky's slots are limited anyway, once they are filled, they are filled, they can't push any more on as BT could.

Could you download and install RouterStats Lite please?

I am wondering if your Noise Margins are changing a lot. If you could run this program and log the data then you could prove this to the people at Sky as the symptom of your problems.

As to the cause, it may help to use it to spot a pattern.

For the record you should expect a small change in the noise margin levels, but in some cases this can become quite pronounced and become an issue.

Since you are using the Test Socket, has anyone suggest a filtered faceplate? It won't cure the current line issues, but it would IMHO be a better option that your current set up.

Also has anyone checked your wiring between your home and the Green Street box to which you are connected? Take a look from the master socket and see if there are any Junction Boxes. As some idea, the following link shows some of the many designs which you might see:

I'll have a look into that.

I have a filtered faceplate, but got fed up of removing the front plate so now just have it in the test socket permanently.

I pressume they did that the first time, as the fault was found to be in the cabinet.

Take a look from the master socket and see if there are any Junction Boxes. As some idea, the following link shows some of the many designs which you might see:

There is a small junction box where the wire comes into the house, the outside line comes into that and then the wires are joined in there and go to the Master socket, but that was all checked on both occassions. There are no components in that junction box, just connectors.

However none of the above would suggest why the line /connection I had previously suddenly deteriorates simply by reconnecting/replacing a couple of wires, either at the cabinet or the exchange.

Thanks for the suggestions

[Scubbie]

Could you post a photograph of the inside of the junction box so that we can see the wiring and which type it is please?

[odds]

Well, I opened the junction box and was quite surprised actually. The last engineer had obviously removed the old push-in type connectors and replaced them with these :
The black one is the line in, then the other goes to the Master Socket.

[Scubbie]

They will make a good connection and shouldn't be the cause of any issues.

It will be interesting to see what RouterStats Lits shows.

I've not asked about performing a quiet line test. Could you do this please?

How? Using a corded telephone, plugged into the Test Socket, dial '1' and listen carefully for any noise (particularly clicking or hissing). It should be totally silent.

Installed Routerstats-Lite and this is the Log file, router.txt

I don't have a corded phone at the moment to try, but I'll get on to that next

Thanks.
