OK so as I understand the issue -
"Trouble hearing me on the phone. Ironically the SNR in my router has dropped by about 5Db and
the attenuation as increased by 2Db".
SNR is the ratio of clear Signal in relation to Noise, if it has dropped
then to me that would tend to be about
what I would expect.
Attenuation and SNR can fluctuate a small amount and that could easily be as a result of physical problems
with the line.
Generally a full install is best and they are far less likely to fail.
I have always said that in the event that there is a
phone issue that you can actually hear, then it is really a good idea
to call that up and report it - I usually focus on reporting the phone fault, not the DSL
fault, as most Telcos set much higher standards for PSTN (Phone services) than for DSL,
as there is a huge range of issues that can happen with DSL, and PSTN is much simpler
to fix, so the "Fobinator scripts" are brought out (eg Oh that must be your modem /
problem etc).
You might find punching your figures into my tool helps (here

though it is in development at the moment, and might have some probs. As you had
said that your SNR had dropped by 5dB that might be irrelevant unless you were
right near the end of range.
Was the DSL speed impacted (I would expect that) or was there any other symptoms?
Hope this helps..
