      Unhappy 40% sync speed reduction

      Hi Guys

      I have noticed a recent reduction in the speed which my router syncs at.

      I have for the past 18 months connected happily at approx 5.5mb/s. However over the past few weeks my router has failed to connect at that speed during the day.

      I can however get and maintain the above stated 5.5mb/s during the night and early morning, but at approx 8:55am everyone morning that speed drops to between 3.1mb/s and 3.3mb/s, and will not allow the other speed again until after 11pm at night.

      Below are 2 screenshots, taken at 8:52am and 8:57am, where you can see the massive drop in connection speed:





      I have made numerous calls to Sky, where they repeatedly attempt to "support" me with my issue, following through their sheet of questions, to then finally get transferred to 2nd line support, who fail to understand why this would happen, and who tell me that my line "should only support 3.5mb".

      After numerous hours on the phone, they agreed to send an Openreach engineer, who again tested the line, said that the line was only connecting at 3.1. I then showed him the screenshots, and he informed me he would have to go to the exchange to check.

      He then called me from the exchange to inform me that the connection speed at the exchange was 4mb, so I was losing speed over the line. I then posed the question as to why this drop in change would have happened recently, and he informed me that Sky may have changed ports at the exchange, which may have resulted in the decrease in speed, and he would file a report to Sky to get this changed.

      I then received a text message from Sky to tell me that my fault has been fixed, without them requiring a hom visit....but guess what, it's not.

      I have again called support, and been through th hole rigmarole again, and now awaiting a call back from Sky.

      Can anyone shed any light on why this may be happening? So I can tell the engineers.

      Many thanks

      Digga

      Odd that the sync speed drops but the SNR doesn't. Does the router actually disconnect then re-sync with the new speed or does it just change?

      It is odd!

      It just changes, no disconnection!

      I have noticed one other change. My IP location always seemed to be Cwmbran before, now it appears my ip is in Nottingham? Not sure how relevant this is?!

      Re: 40% sync speed reduction

      I assume that your checks when on the phone to sky involved removal of the master socket faceplate (if possible) and the replacement of your adsl filter?

      Do you have anything going on in the house during the hours that the speed suffers? Any particular electrical device that gets plugged in for example?

      Can you post the stats again but this time from the TEST socket, when you remove the front plate, check all the other phone sockets if you have any are also dead.

      Yes, and I did this before even attempting to call Sky

      Not that I am aware of. I thought of this myself, but there is nothing that gets switched on at these times. My partner and I are generally at work when the speed drops, and so I have left my pc jus taken timed screenshots to get the images above.

      Stats at Test Socket are currently:

      ADSL Link Downstream Upstream
      Connection Speed 3383 kbps 766 kbps
      Line Attenuation 45 db 28 db
      Noise Margin 7 db 14 db

      I do not have an alarm at the property.

      Thanks for your responses!!!

      I did not think Sky used it, but it looks like SRA is active on your line. That is the only way the speed can change without a resync. Try downloading and running Routerstats Lite. This will show whether your noise margin is dropping and causing the change in speed. You can get it from here-

      Would Sky really use SRA?

      Wouldn't that mean that the speed would then go back up without a router reset?
