I've asked about this elsewhere but not been able to get an answer. Fingers crossed.
The readings below are from my 3Com 3CRWDR100A-72 router. Note the 63dB for the upstream attenuation

I get around 240kB/s download and 30kB/s upload, which is what I would
expect with a two meg connection. I am with Pipex.
The 63dB attenuation figure stays the same no matter what I do. The others
have changed practically every time I check them, as I would expect.
That 16dB download noise margin is normally about 26 to 30dB and seems to
come down to 16-17db when it is raining. The figures don't change much whether
I have the router plugged into the master socket, the test socket, or at the end
of two 5 metre extension leads. I am about 1.3km from the exchange by road.
Can anyone tell me what's happening here with that 63dB attenuation figure,
and if it's going to affect me if I move to Be, expecting a 24 meg connection?
(I'm not *really* expecting that speed.
