ADSL24 is my ISP, I did raise this as an issue with them a couple of weeks back, they told me to contact BT as its a line fault, and BT came back with the line being fine, and that an engineer had to come to check it out and I would be charged £99 if it was my own equipment, which I had a hunch it was so, so I did not call him.

I know, but if their testing cannot pick up such simple mistakes as that, then it does not give confidence about the rest of their testing regime.

1. Is the telephone fine on its own?

2. If the problem is only broadband, then its down to ADSL24 to raise the fault with its supplier, who in turn will talk to the Openreach engineers. At a guess you have a High Resistance (HR) fault.

If you mean like the phone line working fine etc and not disconnecting the internet, yeah that's fine now. It wasn't about a week ago until I changed the ADSL cable and filter, but after changing them two it's fine, it works and the internet doesn't disconnect anymore.

The HR fault, it isn't my own equipment? I thought it was my equipment causing this, but if it is something else then I guess I will need the engineer I guess?

I'd not be so certain that the disconnects have stopped because of the cabling changes, with the 22dB noise margin you currently have it would take a lot to force a disconnect.

In short it looks like your ISP has slowed down your service to cope with some noise issue, get them to put the service back to the defualt 6dB or 9dB target noise margin (which should give you your speed back) and see if it stays reliable.

If the phone causes the broadband to disconnect then, then you need to report a HR fault via your ISP - not via BT yourself.

Alright, thanks! I'll do that. Hopefully it will just work with restoring my speeds. :X
