      Re: Sync speeds and ping during DLM

      I have just connected the Sagem due to peer pressure!

      Stats at present are:

      Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
      WAN MER 37277 51947 0 33 41 0:19:23
      LAN Up 54396 40671 0 710 273 0:20:08
      WLAN Up 25973 18792 0 8126 1032 0:16:52
      ADSL Link Downstream Upstream
      Connection Speed 4095 kbps 797 kbps
      Line Attenuation 43.0 dB 14.7 dB
      Noise Margin 9.7 dB 15.7 dB

      Initial differences are that the downstream attenuation is now 43dB as opposed to 39dB which is quite a difference for the worse.

      This is true, but we can now clearly see that DLM hasn't yet done much work on your connection.

      You should get a connection speed of between 7-8mb.

      Remember too that different manufacturers use different methods for calculating the Line Attenuation. This could explain the large difference that you had.

      Should I be concerned about this?

      It would do no harm to give Sky a call and ask them if DLM is running. If its not you could ask them to set your speed manually.

      Apparently it is running until 18/02 although there was no re-sync overnight last night.

      Still no real change.

      Re: Sync speeds and ping during DLM

      The SNR (noise margin) has gone up from where it was before now showing more speed is available. Not a huge jump above the default 7dB but enough to get to 7Mbps I reckon - so long as it doesn't drop

      Re: Sync speeds and ping during DLM

      Again no retrain last night. Speed remains slow as below. Downstream attenuation is sitting rock solid at 39 with an SNR of 9.

      Not impressed to be honest and the DLM excuse is fast running out.

      Re: Sync speeds and ping during DLM

      Then you're looking at internal setup issue or line fault. I assume you every stats post has been from the test socket?

      Re: Sync speeds and ping during DLM

      You were connected on the 6th. DLM can take 3 or 4 days to start and you are clearly over this now, so it should have done something by now.

      In you position I would be tempted to give Sky a friendly call and ask someone to manually configure your line. Not everyone in Sky's first line of support has access to the systems to allow them to reconfigure the line, so if they can't help, ask if you can speak to someone who can. If they refuse, hang-up and call again. You may need to make two or three calls.

      Please do post the revised connection stats once this has been done so that we can check that they have correctly adjusted both the downstream and upstream connections.

      Appreciate the help guys.

      The last person I spoke to seemed to think that DLM started on 08/02 which whilst not reflected on My Sky the line re-syncs that would take place in the early hours of each morning would indicate that it was running.

      I am connected directly to the test socket and with an XF-1e micro-filter.

      I will give them a call and see what the situation is. Hopefully as you suggest a manual profile config will sort it all out.
