      High attenuation on new line

      Hi,

      I might be being a bit hasty here but I have just had a new Sky Unlimited line installed and I am really shocked by my downstream line attenuation.

      Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
      WAN MER 4312 10836 0 1313 12296 00:12:08
      LAN 17018 14959 0 8802 1797 00:26:40
      WLAN 160 160 0 31 30 00:11:58


      ADSL Link Downstream Upstream
      Connection Speed 896 kbps 608 kbps
      Line Attenuation 63.5db 31.5db
      Noise Margin 6.9db 8.0db

      I am under 1km from the exchange by road and lived in a property across the road 4 months ago which had a constant stable connection of around 16.5mb (I think I had a line attenuation of 27db but can't guarantee).

      A few key points:

      • I have just left virgin during the 28 day cancellation but the BT engineer left the Virgin faceplate in
      • I have plugged the router directly into the test socket with a filter and short telephone cable
      • I am using Cat5e cable to connect my pc to the router
      • The router is the one I had at my previous flat (a Dlink DSL) as they have not sent my new one yet
      • Sky have confirmed today that once DLM is over I should be able to receive 11.5mb minimum


      I am really worried that the wiring is busted seeing as the line attenuation is so high. I tried to get them to look at the line but they can't until tomorrow when it should show as activated on their system. I have been waiting for a long time for it to be installed and just wanted to check if anyone has any ideas as to how this could be fixed.

      You might find that when the line is fully activated it will sort itself out.

      I have plugged the router directly into the test socket with a filter and short telephone cable
      Can you do this using only the ADSL cable supplied by Sky? Trailing telephone cables can effect broadband very badly.

      Oh my word. I nearly wet myself laughing at how stupid I had been. When you posted that I went hunting for a better cable and managed to find one, went to plug it in and realised I had connected the router to the Phone port on the filter.

      Unbelievably embarrassed about that but thought I'd better put a reply in case some other fool does the same thing.

      Stats are now:

      ADSL Link Downstream Upstream
      Connection Speed 4095 kbps 606 kbps
      Line Attenuation 31.5db 18.2db
      Noise Margin 16.9db 18.5db

      Thanks for the help, such a relief that it's working properly!

      Plenty of room for an increase there too with your 16db noise margin.

      I'm surprised it worked at all though!
