      Question noise margin, attenuation etc

      Is this ok or is it a bad sign?

      My current setup is zen internet 8mb and im using a linksys router, always get top speeds and never ever any problems.
      My stats are:
      ADSL Line Type GDMT
      ADSL Line Coding FAST
      Line Attenuation (Down):28 (Up):12
      Noise Margin (Down):12 (Up):26
      Total Output Power (Down):0 (Up):0
      Current Rate DownStr: 8128(K) UpStr: 448(K)

      Im connected straight to the ADSL master socket, no filters anywhere. The socket is the one that BT fitted when ADSL first came out when it was 150 install.

      I've tried plugging the SKY router in and the Line attenuation is 24 on that.
      Im 1.1km from the exchange.
      BT adsl checker says i should get 2mb. If i check by my postcode they say 6.5mb. Sky say i should get 2mb. UKOnline say i should get 12mb. Dsl zone say i should get 14-18mb. Now i know i can get 8mb with no probs as i have been since March.

      Whos right? lol.
      Is it normal for attenuation to change with a different router? I thought id get about 10-12mb but now im totally unsure. 22nd is skymax connection date so what do you think i should expect?
      Thanks.

      Yes you should be able to get 10-12mb on ADSL2+!

      The BT Report is for standard DSLMAx!

      With the stats you just posted you should get very good speed here are mine

      ADSL Link Downstream Upstream
      Connection Speed 15323 kbps 766 kbps
      Line Attenuation 25.0 db 13.6 db
      Noise Margin 9.9 db 12.0 db

      What you need to remember your on MAXDsl with Zen and SkyBB MAX is ADSL+2 hence the far higher speeds reported on Dsl zone.

      Some Advice.. Its always advisable to inform your old ISP as soon as you have migrated that you have moved.
