      You have a very good connection speed for your attenuation.

      Keep an eye on your noise margin though.

      Re: this is what i have

      ok i am now haveing a problem


      Connection Speed 5184 kbps 768 kbps
      Line Attenuation 53.0 db 31.5 db
      Noise Margin 5.8 db 11.0 db


      i am finding that my line attenuation does not move at all its always at 53db

      but my noise margin is all over the shop when i reboot the router it always starts off good but then drops below 5 db and then i lose connection so i have to reboot and it all start's over again have a high noise margin and drops until i lose connection
      have tried this at all times of the day and night is there anyway to force the noise margin to stay at 7db or above

      Re: this is what i have

      Well i did read your post but am confused

      You say

      To "lock" your router to a high noise margin do the following:

      Open a separate browser window, log into the router and open up the stats page and leave it open
      If your noise margin is at 6.5db or lower then reboot.
      Keep your eye on the stats from time to time - if it reaches or drops below 6.5db again then reboot
      Keep doing this until it stops dropping


      But sometimes it does not stop dropping it just drops out all the time i found that between 6 and 10 on Sunday it did not matter how many times i rebooted it just started good then dropped out



      Alternatively have a look at Mognuts' utility in the sticky in the Tech Discussion forum. With this you can change your noise margin at will. If you consider this route then please be aware that there is always a risk that you could mess up your router. Any changes you make should be removed with a reboot but I think I should ensure that you understand the risks involved.


      As for this part you say that you can set it in mognuts utility to 7db
      But by forcing it to stay at 7db will you still get the line dropping out how does it force the router to stay at 7 db



      and yet this morning i am getting

      5536 kbps 7.4db and this has not moved all morning

      Re: this is what i have

      Noise margin will vary through daily cycles.

      The first method given has to work in that if you reboot the router at the time of highest noise then the router is "locked" to that as a minimum i.e the daily cycles will continue but you have set the low point. If the noise margin continues to drop then you can't have rebooted at the time of highest noise and will have to reboot again (and again) until that point is reached. The only time this won't be true is if you have transient high noise (noise spikes) which suddenly overwhelm the router but then quickly go back to normal.

      The second method allows you to adjust the noise margin to practically any figure you choose. What it obviously can't do is stop the daily noise margin changes. Again, what you are doing is setting a level. If you do this at the time of most noise then the figure you set will be the lowest it will then go. If you set it at the time of least noise then the figure will be the highest it will go. You need to choose a figure that will keep the noise margin above say 7db right through the cycles.

      The utility has no intelligence. That part is up to you.
