Variable BB Speed for no apparent reason

Hello All

 

Please forgive the ignorance of a newbie here, I have been trying to search the forum for likely answers to my query. I would be grateful for the advice of others.

 

My query is, following noticing a BT Openworld engineer working down a manhole just across the road from me, I discovered that my broadband seemed to get very slow- 3.1Mps. Now the BT engineer may have just been a coincidence, but the combination of that and the significantly slower speed prompted me to start looking at my hub information.  Which I have pasted below. It doesn't really mean much to me but from what I have read on these forums, it seems to me that my phone line maybe unstable and that it is currently stabilizing ?  There seem to be disconnections, but I have not done any resetting of the hub (having read this is a bad thng to do un these cirucmstances ?), so is this just the line playing up ?  I suspect that the answer to my query will be - you have to wait for things to settle down and then your speed will improve, but I'd be more patient if I knew that was actually the case ! Any comments much appreciaated.

Re: Variable BB Speed for no apparent reason

in general your noise margin is high at 18 as normal about 6 and the disconnections also suggest there is a noise problem on your line.

 

are you connected to the master or test socket or somewhere else?

 

have yu tried the quiet line test - dial 17070 option 2  should hear nothing and best done with corded phone

Re: Variable BB Speed for no apparent reason

Hello - that was a quick response !

The hub is plugged into what I believe is the master socket, where the phone line comes into the house. I do have a phone plugged in there too.

I just tried that quiet line test on my corded phone in the kitchen and I couldn't hear anything...

Re: Variable BB Speed for no apparent reason

as you obviously have extension sockets in your home does the master socket have a detachable bottom half?  if so there is a test socket behind and that is your direct connection to the exchange and it will eliminate any noise cause by your internal wiring. the downside is that your extension sockets will not work and you would nned to connect a phone to the filter in the test socket.

 

also if you remove the bellwire on terminal 3 on the master and all your extensions than that may help as it acts like an aerial for noise  info here http://www.jarviser.co.uk/jarviser/bellwirenutshell.html

Re: Variable BB Speed for no apparent reason

Thank you for your comprehensive advice.

 

I have plugged the hub and a phone into the test socket via a filter for the time being to see if things improve.

I had a look at the bellwire fix, which sounds like a good idea as I have two phone extensions (kitchen and bedroom) but the inside of the box and the wires look rather messiy compared to the photos (there seem to be two sets of four terminals and loads of wires, for the extensions I assume). I shall leave that part of the fix for another day when I feel more confident of what I am doing !

 

Thanks again - much appreciated.

Re: Variable BB Speed for no apparent reason

if you find that there is an improvement with connected to the test socket after 3/5 days then you can think about the bellwire which is normally orange/white should be on terminal 3.  the main extension wires are normally on 2 and 5
