Slow broadband speed after noisy line repaired

Go to solution

I've recently had a noisy line which eventually got repaired (dirty connection on block at local poll). Since then Broadband has remained connected (good) but download speed has been none existant >250Kbps ASDL line details are as below:

 

I'm not getting any progress on the fault I've registered with BT on Dec 12 (says more testing is required), I keep chasing with the online support chat but keep getting the same response "we need to do some checks on the line we will get back to you in a hour or so, an then nothing". Any tips on how to get resolution of the issue speeded up?

Thats a bad downstream connection speed.

 

Please can you connect things up as shown on this link.

Testing from "test" socket

 

and show the ADSL stats again.

Easiersaid than done as the test socket is handly located in the back corner of the loft a far distance from a power extension, but after a bit os swearing and some bruised knees here are the results

Well the noise margin has gone up from 9.2bB to 15.4dB, which is much better, and leaves lots of room for a speed improvement.

 

You must be losing a lot of signal between the master socket and wherever you plug your home hub into.

 

Your estimated final speed should be about 7552Kbs, but you are stuck in a banded profile due to the line fault.

 

You are not going to get the full speed with a margin of 9.2db, but if its not practical to use the master socket, it would be worth disconnecting the bellwire while you are up in the loft, as that may help reduce any problems on your extension.

 

See here for instructions.

Bellwire fix.

 

This could help quite a bit.

Keith, thanks for the information, I'll take a look at disconnecting the bell wire, but I have one of those BT Accelerators face plate things that I think is ment to do much the same thing. I guess I'll just have to keep waiting and leave the router connected until the banded profile is removed (is it usual to be banded to such a low download speed?)

The BT Accelerator can help, but disconnecting wires 3 and 4 is better.

They cause inbalance on any extension wiring, causing interference pickup, which reduces the noise margin.

 

And yes, its not unusualy to be stuck on the lowest banded profile, but leave everything undisturbed, and it should recover after about five days.

 

If it does not, then

 

If you would like to contact one of the UK based BT Care Team who moderate this forum, they should be able to arrange a reset.

 

They can be contacted using this link BT Care Team

 

They normally respond by phone or e-mail, within three working days, however you should get an immediate confirmation, with a tracking number.

Thanks, I'll just leave the router running then.

 

BTW Bell wires were already disconnected so no improvement there.

That is the best option, as the DLM (Dynamic Line Management) will soon realise that the fault is fixed.
