      A once good connection now lousy

      Hi all, have been trawling through this forum today, some really useful info - cheers! Ok, my Sky BB problem:
      Connected in 03.2007, Sky Max, locale exchange is approx. 1.6Km as the crow flys. Initial connection was great; Netgear settings reported Downstream >13000. Over the past couple of weeks however, I've been getting some really poor connections, and at times, I've had no connection what so ever, until I reboot. I only have 2 devices attached to the router; PC (on occasionally, ethernet connex) and PS3 (on few times a week, ethernet connex). This afternoon, I've been making some router stat notes, and have noticed the following ranges over the past few hours:
      STATS:
      Connection speed (kbps): D/S - 193 to 3511 U/S - 288 to 660
      line attenuation (db): D/S - 38.5 to 43.5 U/S - 22.7 to 26.9
      Noise Marging (db): D/S - 1.3 - 18.6 U/S - 0 to 17.5

      The peak downstrea connection speed of 3511 (line att.42.5, noise margin 7.8) occured after a router reboot, but soon went down to 660 (line att. 41.5, margin 13).

      Seeing as I have had a great connection previously, I don't think that it's related to the connection that the router is plugged into (ie wiring). Do the stats say anything to you guys? Finally, there's a C&P of detailed stats below. I'm hoping that the reboot today hasn't lost any previous stats (I'm saving stats from now on, so can compare).

      Thanks for the assistance, hope that someone has some suggestions!

      Re: A once good connection now lousy

      Your attenuation should stay absolutely static - maybe just a move of 0.5db if you're on the cusp between two figures. Your attenuation has moved 5db during the course of a day and that is a pretty strong indication of a serious line problem. Same with your noise margin swing. 3-5db is normal through the day. 5-7db is too much and points to a bad line. Yours moves 17.3db! lastly your stats show an incredibly poor sync speed for your attenuation - again a good indication of a poor line. See a pattern here?

      You need to run a comparative test with your test socket (assuming you have an NTE5). Connect the router directly to the test socket (that's the one hidden inside your master socket) using only a microfilter and the supplied router cable - no plug in extensions, line splitters, phones etc. What are your stats with the master socket?
