As my connection is already working flat out I have not touched it. It may be that I would also be stopped at 9dB but just fortunate that I live near the exchange and can achieve 'full chat' with 9. Message 8 of Maybe the exchange has decided your 15dB was a blip and has reverted? Message 9 of Correction - the increase was to 12dB, not 15dB. It's still a drastic increase though. If you look at the attached graph sr-day.
You can see that it is a normally stable line if you look at the monthly graph sr-month. I monitor noise margin every 5 minutes, whilst my PC is switched on. Message 10 of A bit more on this 21CN Message 11 of Posts: 19, Normally achievable without a problem.
Message 12 of Please note that this method is not fool-proof because lines that have a good overhead of SNR and are able to sync at the full kbps or with Interleaving , will show a higher figure anyhow. Sometimes your Target SNR may not be perhaps quite the best for your line and you may wish to change this yourself, by either increasing your Target SNR to improve stability of your line.
Or it may be that your SNR Margin is normally very stable and you want to see if by bringing your Target SNR down you can perhaps get a bit more speed. The slider is not entirely accurate, and because each line is different then you will have to experiment. But as a guide Rate your ISP. Message 3 of Posts: I assume you'd have to pay extra for the uncapped upstream on adsl2 but is probably worth it for the better line speeds.
Message 4 of Can't say it surprises me. Message 5 of Posts: 12, Thanks: You retain the same upstream bandwith - because low frequencies work well with ADSL. I've got a ticket open and BT called today useless! Perhaps it depends on router model? Message 6 of Posts: 4, Thanks: 1.
Message 7 of I think I can confirm this is the case. Sometimes your Target SNR may not be perhaps quite the best for your line and you may wish to change this yourself, by either increasing your Target SNR to improve stability of your line.
