      Connection drop-outs: is there a solution?

      Hi,

      [details]
      - sky broadband
      - netgear router DG834GT
      - PPPoA

      I am having problems with my internet connection going down, repeatedly, ad infinitum.

      I have seen many posts about similar problems and am guessing there just is no solution and its bye bye to Sky.

      Here is a step by step guide to my situation, the same thing happens over and over again.

      Every night, come home, router says am connected for first couple of hours.

      [step 1] - Then it will drop connection.
      [step 2a] - I can sometimes access the router from my laptop at this stage, if i can i go to reboot router. At this stage the router says...
      modem - negotiating
      all the ADSL settings are blank

      [step 2b] - go and turn the router off and on again at the mains

      [step 3] - router invariably comes up, gets a connection and all is ok until about 5-10 mins later the same thing happens again. go back to [step 1] ntil bored and sleepy :-)

      There are various devices connecting to the router, 2 xboxes, laptops etc. although all of the above issues have been encountered with just one of any device.

      - i have tried upnp off,
      - i have tried dmz on,
      - i have tried port forwarding for the xbox
      - i have switched the channel to 11
      - the wireless connection is always strong from all the laptops etc

      [Conclusion]
      My botched conclusion is that it is an issue at Sky's end as the router keeps losing connection to the internet. So it doesnt really matter what i try at my end.

      Is there anything else i can be trying or should i just ditch Sky, badmouth them a little, get over it and move on?

      Many thanks for your help everyone ;-)

      Ta

      Matt

      Re: Connection drop-outs: is there a solution?

      It sounds like the problem is between your router and the exchange so you need to establish whether this is caused by your internal wiring. Start by posting your detailed router stats using the instructions here:-

      PLEASE READ FIRST: How to obtain and post router stats

      cheers dude

      stats are below

      lots of ES in there, do you think that may be the cause of the above?

      thanks again for your help

      Re: Connection drop-outs: is there a solution?

      Is there any chance you could repeat the stats in your test socket?

      Sky User - The unofficial support forum for everything Sky! How to test your Master Socket

      I may be wrong but according to your attenuation you should get


      ADSL2+ Speed Test
      We estimate your line is capable of between 16mb to 24mb broadband on an ADSL2+ service.

      SkyUser - ADSL2 Line Speed Checker - upto 24mb

      Maybe someone else can comment?

      Re: Connection drop-outs: is there a solution?

      The loss-of-sync (LOS) counts are conspicuously high. There does seem to be some kind of wiring issue here. Running for a while while plugged into the test socket (as NewsreadeR suggested) will help determine whether the problem is between the exchange and your house, or if it is actually the telephone wiring inside your house that's the problem.

      Re: Connection drop-outs: is there a solution?

      Hi again,

      thanks for getting back to me.

      I have looked around the house and can't find a split box like the one described on that link.

      As far as i can see we have 2 boxes, 1 kitchen, 1 front room, both of which are just 'straight into the wall' rather than having that split part.

      Neither of them really look like things i should be unscrewing :-)

      am i being dumb here?

      for what its worth - here are the stats from tonight...

      and bizarrely the pattern exactly repeats of perfectly fine connection til about 9.45 when it starts going into this drop/connect/drop/connect loop that i described in my first post.

      Is there anything else i can look at?

      Thanks again

      Matt

      Re: Connection drop-outs: is there a solution?

      that is a good question.

      I do not know the exact answer but it is by no means a new house. Just a normal terraced house thats been up for ages.

      1 - Its worth noting at this point that we had BT as our provider previously and did not experience any issues. (Dont ask me why we changed, it was something out of my control!)

      2 - I heard from a friend of a friend that one way of sorting this whole issue was to cap the speed. Does this mean anything to anyone? anyone know how to do this?

      Ta again all

      if you have a look at where the BT line enters your house, and follow this to the first socket, this should be the master (if it has a split across that would be an NTE5 master, but some house do not have these)

      (Dont ask me why we changed, it was something out of my control!)
      If you are on the base package it costs nothing (apart from the connection charge)

      your last point about the speed and being capped to improve connection is correct BUT on base you are capped at 2 meg anyway

      have a look at the first link in my sig about posting your detailed stats and post them back
