      Connection suddenly gone abysmal!

      Argh!

      Constant link dropping to both multiple game servers and just browsing the web - i've had to reboot the router over 20 times this weekend - each time it comes up at about 1000 kbps connection with a noise margin of between 6 and 10 db, but within a couple of minutes its dropping as far as 2db!

      Tonight i graphed the noise margin on router - this is with the line synched at 512K, whereas i usually get synced at between 1000 and 1200. When synced at approx 1000k, the noise margin is fairly static at about 6-6.5db

      If i reboot the router and get synched at anything over 800k, the noise margin is approx 7db, but within 30-60 seconds its dropped as far as 2!

      The graph shows how bad my connection has been since Saturday afternoon, Nothing kit wise has changed at my end, no filters have been moved/changed, the router is not running hot, there is no "bad weather" to affect the signal (even although the phone line is totally underground) - i have tried everything i can think of, but nothing makes any difference.

      A shift of 3-4db in noise margin is fairly normal - what's not normal is for it to cycle as rapidly as yours is. Stating the obvious, there's something happening on your line.

      You say nothing has changed your side of the connection but filters do fail and wiring connections can deteriorate. Have you tried the test socket behind the faceplate of your master socket (assuming you have an NTE5)? If you get the same results then that pretty much rules out a problem your side of the master socket.

      That then points to a line issue. Can you detect any noise when making a voice call? If you can then you need to call in BT. With the onset of winter many underground conduits will be flooded. The lines are designed to cope with this but sometimes water can make ingress.

      Lastly, you're on Connect. This means you have to contend with all sorts of issues arising from the rate adaption methodology this uses so any improvements you make to eliminate noise probably won't be reflected in an immediate improvement to your connection speed/stability.

      You are NOT gonna believe what it was - XMAS lights on a house 4 doors up!!

      He has a ton of lights outside his house, on the walls, on the ground, round the garden etc - it was knocking out everyone's ADSL on the street!!!

      Switch the lights off, and hey presto - flatline at 6.5 db on the noise graph - result!

      So be warned, check the xmas lights next time

      I assume you asked the person concerned to cease with the lights or are you all putting up with a ropey connection at night!

      After a bit of playing about, it seemed to be a rope of lights he had strung round his grass at front, he's moved it onto his fence round his back garden and alls well, so he can have his lights on and all us geeks can have our adsl

      Wow amazing - my router has been dropping noise margin and disconnecting from 4p.m onwards since a week before Christmas whereas it was rock solid before. I'd wondered whether it could have had anything to do with Christmas lights but this confirms it now.
