In reply to a post by Cycle194:

I'm considering calling out BT again to remove the connection to the second box (only the cost puts me off, which is why I'm hoping to get as much a guide as possible if it'll help or not).

How/where is teh second socket connected?

If it is done correctly then your should be able to do it your self.

Can you link to images of your master - front plate, what is connected to the back of the plate and wires inside the back box.

Hang on!

We seem to have established you have star wiring, (a split before the master socket). Assuming the router is plugged into the master socket, (the one with the split faceplate), is anything plugged into the other? Which you seem to be saying doesn't have a filter.

Have you got any more phone sockets around the house? If yes, is anything plugged into one or more?

There seems to be a black box high up, just under the roof. I assume the BT line goes in there and there are two lines coming off which go into two different parts of the house. One is to what I thought was the master socket, the other goes though a window to another socket which is unused (but appears to work).

Only the master socket has anything plugged into it, the second box is unused. To my knowledge, there are no other boxes.

My connection has been fairly reliable for the past day oddly enough, but there was a disconnection today. It seems as suspected by some, the SNR margin rapidly dropped and the connection failed. It took three minutes for the SNR to recover. The connection speed is now at a lower, but still reasonable rate (3232), and the SNR margin is higher than it was before (7.6 to 9.3). I wasn't in the house at the time so there was nothing obvious that caused it.

Can anybody recommend a good temporary image sharing site? I can then show some graphs to illustrate things as they happen.

Thanks

The location of the source of the extra cabling ,means it could be a problem - the length of it will be a significant factor in how it interferes swell as being an antenna for noise. Even though not used, try a filter on it, it may improve performance and is easy to add and remove.

Getting the line removed is not easy and needs a BT visit.

Thanks for the Photobucket suggestion, but it seems to need registration, so I found another site that avoids that.

Here are a couple of graphs that show disconnections (SNR):-

What do you all think?

Thanks

A further interesting sequence of results from roughly 3am to 7am on the 9th:-

Don't like those links. They want to download something to my PC. We just wanna see them.

There is nothing wrong with photobucket - registration is easy and free. It would also allow you to put a set of images in a sub-directory and then with a single link a viewer can scroll across them rather than going for individual ones.

My PC complains about your links - they push CPU time right up.

Thise two massive dips in SNR suggest that a large noise source is starting up somewhere and that could be a cause. The small 1dB increase are something changing or being switch off - a minor problem which may not be as easy to resolve.

Minimise the connections to the line - no extraneous wiring or phones and leave it running again tonight. Do they happen at the same time?

If I click "Open" I get a list of things to choose from to open them, including IE which works fine. So does Chrome.

But as MHC has just said, to be able to scroll through them would make things a lot easier.

Strange, they just just display an image for me.

I'm using Pale Moon 25.1.0
