on the 7800DXL is the way the SNR tweak works any better with BT Dynamic Line Management, as on the 7800n it always seemed to change the SNR to get it back to 6 every 10 days or so. ... so if I had an SNR or 6 tweaked it to subtract 3 to give me a SNR or 3 after 10 days or so the BT DLM would increase the SNR to 9, so i would then have to tweak it by subtracting 6, then another 10 days it would go 10 days it would go to 12 so I would have to subtract 9 etc etc.

the conclusion we came to on this forum was that it was the DLM as it was always going back to 6 plus the tweak number subtracted. ... I gave up trying to tweak.

one recommendation was to request the ISP set a hard target of the SNR, but my ISP tell me this is not possible.

If i start tweaking the 7800DXL, am I going to get into the same trouble?

how do other people get around this? Does scheduling a reboot once a week help?

Thanks in advance

I've always been of the view that trying to tweak the SNR on a BT Wholesale line has been pointless because of the way that the BT DLM (BRAS) system works.

I've managed to do it on Orange's LLU (before they went to BT) & on Sky's LLU but on BT it's never work successfully.

I am rapidly coming to the same conclusion, which is a shame as it was one of the concepts I was hoping would get me a little extra download speed and reason I actually bought a 7800DXL... I do not usually use any of the wireless or there features ... I just wanted the best stability / speed i could get out of the ADSL line.

unfortunately LLU is highly unlikely in my exchange, we are only just going 21CN, as for FTC ....

I was just wondering if there was anything I can do
