      Difference between Max Attainable Rates and Actual Sync Rate

      Anyone else noticing a big difference between these two values?

      My Sync is 64000
      Attainable 75000

      SNR is 7ish, so can't see any room for improvement there.

      Anything I can do? I guess ringing Sky will be of no use as I shouldn't "know" my attainable rate

      Re: Difference between Max Attainable Rates and Actual Sync Rate

      I don't have access to my SNR but my synch rate is 35176 but download speed is 28000. My BT modem is an ECI so did consider buying a Huawai one from fleabay and see if I could hack that to obtain SNR but then what could I do with that? If we use Billion router/modems does this mean you can adjust the SNR to better the download speed like the old DGteam firmware, as we could use DD wrt but am unsure that allowas you to telnet in to adjust it.

      Same experience here.

      Max Attainable 73188
      Sync 62866

      It synced higher at first but my when my speed tests were all over the place (turned out to be my wifi) i bounced the modem a few times and it resynced at what is it now.. oops! been like this now for a couple of weeks so i assume its not going to go back up.

      I would like to know how many peoples connection does actually go back up once the download speed has suddenly dropped, I'll bet it is a very rare occurence.

      Re: Difference between Max Attainable Rates and Actual Sync Rate

      I've read a few posts from infinity customers about it dropping and not going back up, apparently a profile reset requires an engineer to come out to the cab...

      Tbh I thought it was the reboots that did it but if Gorebrushs is the same perhaps it is the most i can get on the line.

      Re: Difference between Max Attainable Rates and Actual Sync Rate

      Are the speeds it shows in the router settings actual sync speed or max attainable rates?

      I may be wrong, but I think the maximum obtainable may be what you would achieve with a zero noise margin.

      Re: Difference between Max Attainable Rates and Actual Sync Rate

      As I've said on the forum before when I went from 40/10Mb to 80/20Mb, I started at around 69Mb and over a time of several days it went up bit by bit until I got to where I am now 78Mb. So DLM does work.

      Re: Difference between Max Attainable Rates and Actual Sync Rate

      Powercut this morning has resulted in it dropping slightly again to 63000

      Not complaining, just that Max attainable rate is teasing me (74000!)
