Re: download speed halved.

Thought I would give a mini update, Mods managed to reset the noise margin/banding last Thursday (21st), Speed was alright for the first day or two then started dropping, obviously still in the 10 day period so waiting on that to settle itself down. Had a good few drops since the reset but I guess that is the line finding the correct profile? not too sure if DLM drops the line to make its changes or not.

Line has also got back to interleaved.

This is the speeds at the time of each re-connection.:

 

I take it this is DLM finding the correct speed????

Re: download speed halved.

So woke up this morning to a tear inducing download speed of 576Kbps . Which is brilliant on my day off. Please tell me this is just DLM messing around to find the correct profile, just seems to be getting lower and lower!

Re: download speed halved.

you appear to have a line problem and this is nothing to do with 10 day settling period

as mods reset your noise margin and in so short a time you are back in fact worse than before suggests a problem with your line

check your line for any noise   dial 17070 option 2  should be silent and best with corded phone

are you currently using the test socket with a filter to see if that helps your stability  also check any extension socket to make sure there is no dial tone when you are connected to test socket

there is no point in resetting noise margin again until the underlying fault is fixed and you can get a stable connection

Re: download speed halved.

I only have a cordless phone, light hum but also seems to be some rustling almost like someone scrunching tissue paper. connected into an openreach MK4 filtered faceplate (only a few months old, was put in by engineer after lightning damage), unfortunately I gave away my filter to a friend to use so I can't use the test socket but I know there are no internal wires at all as the line just comes straight into the house.

There are a few new houses being built and a business next door, not sure if that has anything to do with the problems.

Should I call BT and log a fault? Looks like I need another engineer vist.

Re: download speed halved.

it would be better to try test socket with a corded phone even when you have a filtered master socket  any noise on cordless apart from dull hum is a problem but better with test socket confirmation.  this helps avoid the engineer call out charge of £85 if problem in your home

Re: download speed halved.

Just off the phone to BT, got an Irish call centre which was really good, she understood everything I was saying and was really quick in sorting everything, didn't even got put on hold once! Apparently it is an external fault and they are sending an engineer out to fix it, been told it should be fixed by Monday so I will keep my fingers crossed and will struggle along with it as is. Then I imagine I will need another reset to get things back to normal.

Thanks for your help imjolly I will post back once fixed to update.

Re: download speed halved.

assuming you actually do get engineer to fix a fault then hopefully your line will stabilise on it's own and then speed increase without any assistance

Re: download speed halved.

So engineer came around yesterday and found a ground earth fault, he fixed it there and then and the line showed no errors on his test, he tried to get a DLM reset done to get the line back to normal but the lines were too busy. 

 

I phoned BT and they said they would get a full reset done, few hours later it went down and came back but no change in speed, phones them about 20mins ago and they have stated they have done a full refresh that will happen in 1-2hours, is this the same as a noise margin reset??

 

speed currently is like dial up, horrendous to try and use especially on a day off from work...
