For year my down and up SNR have been about 60 (X 0.1db) on the Draytek. Recently (sometime in the last few months) the up SNR is now more like 120. The down is still 58.
Any ideas? Nothing has changed that I know of.
Thanks.

The router tells me the attainable up rate is 24 meg but the product is capped at 20.

Quote from: slime So because I'm at 20meg up and thus hit the limit the SNR goes up?
Yes, because VDSL2 is adaptive and has a target SNR margin (usually 6dB). So the rate you get is usually determined by that 6dB SNR margin. Since you have such a good upload speed and are already at the maximum rate for the product, there is no need to have a target 6dB. That 14.4dB SNR margin you have shows there is lots of SNR margin to spare (if that makes sense). It is a really good position to be in.
As to why it has increased, as the other posters have said, it could be any number of reasons, including G.Inp being applied on the line (although I don't think that alone would account for such an increase), changes to your internal wiring, changes to the wiring between the cabinet and your property etc.
