      Noise Margin Question.

      Hey all,

      I'm still capped at 512kb! - and the connection stills drops! :P

      -But I noticed something... when the noise margin fluctuates up and down (range of 20-40db) the internet can stay up for as long as 15 minutes to 6 hours.

      -But when the noise margin is pretty much static the internet is incredibly stable..

      My Question: Is the noise margin suppose to be "near enough" static?

      The router has been on for 7+ days.

      UPTIME: 22:39:48

      ADSL Link Downstream Upstream
      Connection Speed 512 kbps 416 kbps
      Line Attenuation 26.0 db 17.0 db
      Noise Margin 33.0 db 13.0 db
      (Noise Margin has been consistent today)

      Thanks.

      Re: Noise Margin Question.

      wtf! with your stats you should be getting excellent speeds?!

      have you phoned sky??? are they not willing to uncap you!? maybe the router is faulty, have you tried any other routers???

      my Noise margin fluctautes between 8.5db daytime to about 7.8-8.0db in the peak evening times. there is definately something up with 1. either the router, or 2. some little Leprechaun is playing hey diddle diddle on your line!

      Re: Noise Margin Question.

      Thanks for the link... but I don't think the answer I was looking for is in there.

      Yep.. Sky have replaced the router and done all the normal tests... Their final conclusion - Faulty equipment... BT has to check something...

      The connection hasn't dropped yet...uptime: 39:11:51

      But I don't want to get my hopes high. Last time I was connected for 60 hours... so I decided to reset my router to see if it was permanently fixed... but after restarting it... I found out that the connection was still dodgy...

      Re: Noise Margin Question.

      Where I work if downstream margin drops below 9db we get the line checked for faults.

      Attenuation is affected by your distance from your local exchange. It shouldn't change by more than 1 point unless you either have an extension cable on the line or have physically uprooted and moved your building!
