      Sorry but you're getting a bit mixed up there. Nif619 is on Mid which is capped at 8meg. As his attenuation is only 27db, unless his line noise is very bad, his noise margin is bound to be higher than the router default of 6.9db.

      A high noise margin on its own won't result in slow downloads - quite the opposite in fact as line errors will be much lower than with a low noise margin.

      Re: Slow Download Speeds

      OK, I SAID I WAS A NOOB SO DONT SLAUGHTER ME.

      I GUESS I HAVE DONE SOMETHING WRONG BECAUSE MY DETAILED STATS CAME OUT AS :-

      <HTML>
      <HEAD><TITLE>404 Not Found</TITLE></HEAD>
      <BODY BGCOLOR="#cc9999" TEXT="#000000" LINK="#2020ff" VLINK="#4040cc">
      <H4>404 Not Found</H4>
      File not found.
      </BODY>
      </HTML>

      MY SIGNAL STRENGTH AT THE MOMENT IS VERY GOOD.

      I AM ALSO CONFUSED ABOUT WHETHER HIGH NOISE MARGIN IS GOOD OR BAD???

      anything over 7 will be fine, higher the better.....the file you save from getting your stats you open in notepad/wordpad and then post them up...

      Re: Slow Download Speeds

      Then why does my broadband become unusable when my noise margain is over 12? I'm confused by that statement...

      Re: Slow Download Speeds

      No-one is going to slaughter you (though typing in caps is like shouting).

      The signal strength reported by your connection is just that signal strength. That doesn't necessarily mean that the connection is good. If the signal is full of noise then the equipment has problems determining which is noise and which is data. It is quite possible (and quite common) to have an apparently good signal but a very poor quality connection.

      Yes, you've made an error with the stats. Read the instructions again and have another go.

      There's no single answer on whether a high or low noise margin is good or bad as it depends on the circumstances. All other things being equal though then high is best. For a detailed explanation see the first sticky in my signature.

      THESE ARE THE STATS I GET WHEN I ASK FOR DETAILED STATS.

      THE INFO OPENS ON NOTEPAD STRAIGHT AWAY.

      Re: Slow Download Speeds

      You're shouting again

      Do this:

      On the Mognuts page click the Get detailed modem statistics button
      Click OK on the pop-up
      Click the back button on your browser to get back to Mognuts
      Click the Download Netgear cfg file button
      Save the file and open with Wordpad

      STOP SHOUTING ! LOL!

      You have quite a high level of CRC errors, best thing is to plug your router into the test socket behind the face plate of your BT master socket, thats the first/main one. By doing that it disconnects any extension wiring, so if things improve there you know you have internal wiring problems which is very common.

      Re: Slow Download Speeds

      I will do this when I get home this evening, although I did this yesterday and did not notice any significant improvement.

      If (as I expect) this does not imrpove the speeds what else can I do????
