      I must of been having an odd mo because for some reason it had also been changed from bskyb to busby.

      That should get about 7.2Mbit/s on ADSL2+ providing everything is ok with the line.

      The noise margin looks about right, however what the modem is not showing is the modulation so I can't see if that's been set to ADSL2 instead of ADSL2+ or something equally as stupid.

      There are a few possibilities that spring to mind since it's affecting multiple users in the same area, but without more information I can't be more precise.

      1) Sky have replaced/upgraded the equipment at the exchange and the line profile has changed.

      2) Openreach have replaced a section of cable somewhere between the exchange and your street and the new cable isn't as good as the old one was, seems rather unlikely but not impossible.

      3) There's some kind of interference in the area that's knocking out a load of the frequencies that the ADSL2+ is using.


      The first one would be the best case for you as it should hopefully stand the best chance of being fixed providing it gets to the right person at sky they can probably reconfigure the port to try and improve things.

      I really hope it's not either of the other 2 as I doubt openreach will replace a length of cable for a couple of Mbit/s lost off broadband speed and if it's interference then it's going to be a real headache to get sorted as it requires someone to track down the source and then depending what it is it may or may not be possible to get it rectified once located.
