      Would spur to old BT modem breakup signal?

      If I remember correctly, when I first got BT broadband the engineer added a front plate (/splitter) to the main box in the hall but, there's also a box in the living room that my old Alcatel flat fish modem used to plug directly into. I'm pretty sure the living room box is wired into the main box in the hall. Will this reduce the speed of the data arriving at the router?

      Compare your router connection speed plugged into its normal socket and then plugged into the test socket which you'll find behind the faceplate of the master socket.

      If you get a jump in speed this would indicate that some internal wiring is adding noise. It also indicates that you probably need to replace the BT fitted filtered faceplate with a newer one (they can degrade over time).

      Re: Would spur to old BT modem breakup signal?

      Tried that earlier Saturday. No change . My actual speed (~9.5 mbps) falls some way short of my supposed speed (15mbps) so, I was hoping this might be the cause. Could it be that the cabling for the spur took place before the signal split (the living room extension looks like a splitter as well)?

      Re: Would spur to old BT modem breakup signal?

      It's possible that the spur is taken off before the master socket.

      Is the spur still active when the master socket faceplate is removed (this should stop all extensions working as they would normally be wired to the faceplate). If the spur is/was for an ADSL connection then running it from the back of the master socket not the front would be right.

      When you say your actual speed is lower than your supposed speed do you mean router reported speed and speed site reported speed?

      I'll take a look at that later Saturday. Thanks.

      After hassling sky for a few weeks (and getting nowhere) I complained to the ISPA (see my '400m from exchange' thread in 'Speed tests and how to get ...' section) and my connection speed (as shown in Netgear Gateway) went from 8096 to 15323. My actual speed, using Namesco BroadbandMax ADSL Broadband Bandwidth speedtest | Test your ADSL Broadband connection speed suggests I've went from around 6.7mbps to 9.8mbps. The latter figure is very disappointing given my line attenuation (~20) and noise margin (~14).

      Re: Would spur to old BT modem breakup signal?

      It turns out the splitter in the living room plugged into the main splitter in the hall (I had stuck the hall end of the cable under the carpet as it was no longer needed) so, that obviously isn't affecting my speed. I opened up the bt master socket and found two wires going into terminals B & E (I think) with the rest lying loose which I gether is the norm. Can anyone else think of a reason why I'm only getting around 9.5 mbps (wired or wireless) with the following stats?

      ADSL Link Downstream Upstream
      Connection Speed 15323 kbps 766 kbps
      Line Attenuation 21.5 db 11.8 db
      Noise Margin 13.5 db 11.0 db
