Well that's cleared that up thanks. When I reboot the router first thing each morning it generally syncs at an SNR of around 8-9 which, whilst not particularly good, is reasonable. At night, and sometimes during the day, this drops to around 7dB and on a really bad day (thunderstorms etc) to 6 and below. The resyncs are probably due to sudden noise spikes rather than general degradation although 7dB is a bit marginal. Already today it has done one resync and SNR is a steady 9dB. I live just over 3K from the exchange so it should be better than it is.
I've run out of tweaks for the Draytek. If I try to force a higher SNR by setting maxdnrate to below 101 it enters an endless cycle of retraining so the only alternative (which may or may not work), is a different router such as the Speedtouch range. However I see on another thread that the latest firmware for these removes one of the best tweaking methods so it looks as though that avenue may be closed. A borrowed Zyxel syncs at a much higher speed but SNR seldom gets above 6dB. I doubt that long term this would prove any better than the Draytek, particularly since the Zyxel seems pretty un-tweakable.
Progress, aint it wonderful :-)
