broadband speed v copper line

[big john]

As someone who is supposed to be on max, but capped at 4500, I wonder if bt had to put me onto another line, would that perhaps give me a better dnload speed. Surely if the bt bubble connections are old and possible corroded, then that would affect my speed. Also does anyone has a list of exchange max speeds allowed.

thanks

My noise margin is 17 and line attenuation is 44

Have you tried connecting using the test socket on your BT Master Socket (take off the faceplate to reveal the test socket)?


If that improves it, then consider getting a filtered faceplate, and/or disconnecting the ring wire.

yep, this is going directly into the master socket.
I am convinced that the problem is copper wire related. The problem is getting bt to change the line for another.
I had an engineer here with a laptop and he tested the line for reflections etc.....but went away and never came back. I am 1.8km away from the exchange.

The master socket won't help you see if there's a problem with your internal wiring. Only when you have eliminated that should you consider that the wiring to the exchange could be the problem.

As Tezcatlipoca suggested, you have to use your test socket.

BTW With an attenuation of 44db your highest possible connection speed is a shade over 8000kbps i.e. your maximum speed is pretty much the same on Max or Mid.

ok, well I am going to have a closer look at the socket and see how many wires there are.I dont have any extentions in the house, so that will rule that possibility out.

I have plugged into the test socket and still the same. I also check the wires and there are only 2 connections.

Without telling us what your stats are with each connection it's not possible to give any advice.

You say you tried the test socket and it was "still the same". Everything stayed the same? If you are capped as you say at 4500kbps then that's not going to change - but the noise margin may have. If so then that indicates a local problem (the two tests need to be within a few minutes of each other to avoid normal noise margin shifts).

If the results are the same then you might just need the cap removed so you can get the full 8000kbps your line is capable of. You have a huge noise margin (because you are capped) which actually indicates any problem on your line isn't that great i.e. 4500 and 17db probably equates to something around 8000 and 7db.
