      How is line att 41.0 db on sky, but it was 34.0 on Orange

      Hi all, I am very happy with sky speed and reliable connection, but the 1 question I have been wondering is on sky I have a line att of 41.0 db, which the checker says I can get between 8 - 9 Mb and I sync at around 8176 - 8600 ish. Yet on my Orange livebox, I got an line att of 34.0 db, which when I entered it into the checker it said I would get 10 - 12 mb.

      Would being the fact that I am now on ADSL2+ rather than ADSL like Orange was, that the att is going to be different??? still plugged into the same extension as the livebox. Thanks.

      Anthony

      Attenuation is largely a measure of line length. However, attenuation will change with the frequency of the signal being measured.

      ADSL2+ uses higher frequencies than other ADSL modes and typically you'd see an apparent increase of 3-4db when moving to ADSL2+.

      Secondly, there is no fixed/standard way of measuring attenuation that is used by the router manufacturers so it is quite common for two different makes of router to report different attenuations when connecting with the same line.

      On the Sky network on ADSL2+, using a Sky router, an attenuation of 41db using a relatively quiet line, you'd expect a router sync of ~10500kbps.
