      should down snr drop?



      My normal daytime router stats are consistently as below

      Downstream Upstream
      Data rate(Kbps) 5152Kb 832Kb
      Noise Margin 12 12
      Output power(dBm) 119 200
      Attenuation(dB) 33 21

      Whilst all other figure remain constant however the down noise margin drops every evening to 6 0r 7 with one bad evening of 2.

      Download speed is fairly consistent around 4Mb although serious drops have occurred occasionally and I understand the attenuation figure should give 5-5.5mb download speeds.

      My setup is the router connected directly into the master socket fitted with an adsl nation nte5 facelate. From there on it is wireless but my laptop is within two metres of the router. there seems to be about six other available wireless connections available to my PC {all protected}

      Despite much reading of this forum I am still confused by the evening / weekend snr drop. Is it to be expected and are my figures typical? It does seem evening and weekend traffic increases cause my problem but is this a line or wireless issue. Would a direct connection between PC and router improve matters?

      Observations will be greatly appreciated, I basically dislike inconsistency.

      Have a read of this
      http://www.skyuser.co.uk/forum/route...explained.html
      Specifically the " What is the right noise margin " section.
      That should explain things.
