Quote from: purleigh Have you considered buying a modem/router that allows you to permanently override the target SNR ?
so that you don't have to tweak it with 'RouterStats' every time your connection re-syncs.
The obvious choice would be one of the Billion BiPac 7800 series,
although I also got great results with a Netgear DG834GT flashed with DGTeam firmware.
I wish my Netgear DGND3700v2 have these permanently override the target SNR but it doesn't. I thought plusnet can tweak snr target of 2 at their end.

Quote from: goldenadsl When is the best time to tweak snr from 3 to 2dB? I think around 1pm to 2pm are the best time to do it?
When the Sun is at it's highest in the sky (i.e. mid-day) would be the best time. The interference will therefore be at its lowest and you will get the best speed. However (and it's a big however), this speed (i.e sync speed) may not remain when it gets dark. This is because the SNRM tends to drop, on average, by 1-3dB when it gets dark (nearer 3dB at this time of the year), which may cause your connection to be unstable or just very slow due to high error rates.

Go under 3dB and your router is going to be working damn hard to perform bitswaps.. nvm deal with errors.
Id certainly not recommend a 30dB atten line running at under 3dB.... bit different if you have a rock steady 5dB atten line that never ever budges.
This is a perfect example of why BT stopped people from being able to tweak their routers.. then moaning when things broke
*adsl1 needs min of 2 bits per bin because of differing overhead algorithms hence the starting 6dB on adsl1

Quote from: goldenadsl Fault team told me to ingorne it, it was 11 errors over 10 days which it ain't bad.
A few hundred errors per week are okay (not really ideal, but no line is ideal anyway) but 132668 CRCs in the time period of 12 days (that's over 10000 per hour!) suggests to me that your line is not good enough to run that low. The thing is, you can tweak your line as much as you want, but at a certain point, the errors slow down the throughput so you don't notice any difference any way. I am sure that at night, your line gets much slower.

Quote from: goldenadsl It now less errors on 3dB over 24 hours.
Please post a screenshot?
