Thanks tiffy and all,
Ok i think the drop i would now put down to subsciber additions as the graphs look near, had 74 meg initial sync which has dropped to 72 then 70, i've just changed isp and that has placed me from a 3.3snr up to a 6.3snr.
Don't think the ISP can do anything with this or OR?, line has been running now for just over 48hrs and no change, i think i might have to try the manual line capping to try and nudge dlm to apply back to a 3.3 profile?
Any suggestions here? wait, contact isp (ZEN) for help or try a cap, Edit:whoops i presume i may have interleaving applied due to the change over, how can i tell as the stats look pretty much the same apart from the lower 60meg and 6.3snr sync rate i'm now on and if so, how long does interleaving usually last for?
Thanks,
