This graph is speed v distance, which suggests you'd want to be within 1300m of your exchange to hit 22Mb. I've seen a suggested conversion factor of 13.81 for copper to go from attenuation to distance. 22 / 13.81 gives a slightly further distance of about 1600m, suggesting a max speed of 16Mb. Six of one, half a dozen of the other I suspect.Sunray said:Yup, its 12Mbs at the moment but looking at the line stats they are quite good so I am going to leave it a few days to see if it jumps as part of its training that the DSLAM does and if that does not work have a word with Be. According to a chart i saw with a line attenuation of 22dB I should be getting 20Mbs.

As you've got shitloads of extensions inside the house I'd be tempted to whack a filter on the master jack and stick the router on it for a few minutes just to eliminate your internal wiring and see if the attenuation figure improves (not that it really needs to, 22db is bloody good; mine is over 30)
What's your current downstream SNR margin ?? Is it large enough to suggest there's more scope for speed tweaking ??
What 2+ router did they give you ??

I have filters on all the extension sockets.
There is a nice tool called DMT which shows how the line is behaving across all the tones. There are quite a few gaps for me, the middle of the graph is showing that the line isn't so great across all frequencies.
