      Used To Get Better

      Hi,

      First post here, over the past couple of weeks i've been checking out my connection stats for my router and noticed that its been connecting at about 4000 Kbps where as a couple of months ago i'm pretty sure it was connecting at about 6000 Kbps. Also been having a few issues with connection speed dropping to about 700-800 Kbps, but it's not a regular thing.

      Heres my router stats, is there anything unusual there? should I be getting better speeds?

      Re: Used To Get Better

      Mmm, I personally havnt seen that showtime retrain 8000 before.
      Could be dlm I guess but I thought that was for new users only at the moment ,maybe one of the skyguys could confirm or otherwise.
      With your attenuation you should be able to sync at around 6.5meg which bears up your recollection of syncing at 6.
      You have quite a lot of errors, do things improve any in the test socket ?

      Re: Used To Get Better

      There's only 1 socket in the house by the door where the phone line comes through the wall. Just had a look at it and there is no test socket, think the socket we have is quite old.

      We've had sky broadband for over a year now, so it's only been the past couple of months that it's been like this.

      they seem pretty similar to the other ones I got yesterday, exact same down/upstream rate.

      Might sky have capped my speed?

      Re: Used To Get Better

      Your line has been subjected to DLM and has been left capped on ADSL2+. It has probably been like this for some months. It would probably do better on G.DMT as very few lines with a high attenuation benifit from ADSL2+. Call Sky and ask them to trouble shoot a slow connection and possibly move you to G.DMT.

      Was gona say the same thing.

      Your Snr has improved since changing the filter though.

      Think i'll give sky a call sometime then, I thought DLM was only being trialed on new customers?

      I had rebooted the router since i had got the original stats I posted, as I had noticed the SNR was low, so the new filter didn't improve the SNR.

      Will getting a newer socket fitted by BT/myself so I can fit a filtered faceplate be worthwhile to reduce the errors that were shown in the detailed stats?

      It is at the moment, but it was run on 300,000 lines some months ago. I looks like yours was one of them. Normally a Mid connection would not be on ADSL2+, although some are.
