      Question regular disconnections (usually about 9pm - stats included)

      Hi guys and gals, great forum you have here and i've been reading many interesting threads, unfortunately its time to post one of my own

      i've been using the max package since about july, and have experienced problems pretty much since day one. the most annoying of which is the regular 9pm disconnection (give or take 20 mins). its easy to spot when its going to die bc it goes down like an milan goalkeeper, 5 mins after the problem started.
      basically it will slow down to the point of loading web pages very slowly (almost dial up speeds) and then BANG! it will lose the external IP addy.


      hopefully the following info is of use to someone on here........

      basically the phone wire comes from the pole outside into the side of the house and once inside, goes into the back of a little box (about the size of a couple of AA batteries side by side), then a cable from the front of said back into the master socket on the wall.
      i've checked the MS albeit a while ago and am pretty sure its right. from the MS there is a 2 port splitter which has an extension for the main phone and then an upstairs extension which has the router plugged into it. both extensions are filtered.

      im using the sky netgear router which has all 4 wired ports used and only very very occasionally the wireless. there are 3 devices regularly active, which are my PC, my dad's pc and my xbox 360.
      i usually unplug the routers power cable when i shutdown my pc at night, and plug it in again in the morning when i switch on before work. UPNP is off which is how it came from sky.

      my router shows different connection speeds at different times of the day ( i presume this is due to the contention ratio?) usually roundabout 6 meg int he morning and when i reboot in the evening about high 4 meg low 5's.
      i've tried plugging it directly into the MS with no extensions or anything, and i got 8.1meg so i know im losing a couple of meg bc of the extensions.


      i took some detailed stats this morning before i left for work:-

      would someone be kind enough to translate all those numbers into something i can understand please. also is it possible to tell if I’ve been capped and would I be able to get the full 16meg being about 2.1km from the exchange?

      Really - are you sure? Every router will come with the same configuration and UPnP is definitely on by default. That's nothing to do with your problem though.

      No, not contention ratio. See the first sticky in my signature for an explanation of the cause.

      Your first set of stats don't show much as they cover too short a period. Your second set show a very high level of errors. Something is causing them (line noise) and the 9:00 timing may be significant. Are there electrical items in your household switching on at this time e.g. central heating, immersion heater, electric blanket, baby monitor etc?

      No you won't get anywhere near 16meg with your attenuation (which indicates a line length of ~3km). However, you should be getting more than 5meg, more like 10meg. The shortfall is down to your line condition which must be poor. You have not been capped.

      See the cabling and faceplate help forum for info on diagnosing and fixing line issues.

      No mention there of your Sky TV box. Have you remember to use a microfilter for that too?

      Had same problem for 2 nights. Have severely autistic child who likes to surf all night, so up all night reconnecting. Yesterday, got really fed up and put old router back on (netgear too, older model). It's worked fine since, might be a coincidence though. Just have to get used to sleeping at night again.

      yeah sure about UPNP because ive only just heard it may cause problems, and when i went into the router to switch it off it was already un-ticked.

      no nothing like that, we dont have central heating, immersion comes on in the early morning and no electric blankets or kids. the only thing i can think of is my dad usually uses his PC about 9pm, however if he goes on a bit earlier (say 8:30pm) it still goes about 9pm. even if he doesn't switch on it still kicks out. i also left it going over night and it below dial up speeds when i got up at 7am.

      when you say line, do u mean from the pole to the house, or the internal wiring? i agree, something isnt right somewhere. just out of interest, how can u tell from those stats ive not been capped?

      is it possible sky or bt could send a signal down the line to force the router to D/C if say its been on longer than X amount of hours?

      i have a feeling the sky netgear routers have major issues, and this maybe one of them, however i think some of my problem lies with my phone line.

      im considering putting in a different router as ive got a very older netgear (big silver thing) that i used to use with my old tesco broadband, a slightly older netgear (small white one like the sky one) and a BT voyager all in my house not being used

      I think you answered yourself when you said

      "'ve tried plugging it directly into the MS with no extensions or anything, and i got 8.1meg so i know im losing a couple of meg bc of the extensions."

      Also from what you say the extensions are the 'plug in' type, not hardwired. These are not really suitable for broadband and will give you nothing but trouble. There are some on the forum who would be glad of that 'couple of meg' you seem to dismiss. If you have a look through the Cable and Faceplate section, this will give you some ideas how you can improve your connection.

      ^^^ That's a very good point ^^^

      If you're using microfilters rather than having a splitter faceplate on the master socket, then the ring wire serves no function whatsoever other than acting as an aerial to pick up interference on. Disconnecting the ring wire at the extension end helps a bit, but the real benefit comes from disconnecting it at the master socket end, and you can't do that if you're using the plug-in type of extension as opposed to a hard-wired extension.

      i think i'll get a picture or 2 up tonight when im home, as it would make things much clearer
      i know i dismissed that couple of meg im losing, but i was coming from a 512k BB connection, so 4 or 5 + meg seemed like a hell of difference and wasnt really bothered about not being able to get the full 8. to be honest i only expected 5 or 6 in the very best case bc of being so far away from the exchange.

      i've had a look through the faceplate section and there's some good stuff in there, espec them faceplates that you can plug the phone and the router cable into at once, but my MS is downstairs and the router is upstairs.
      whats the longest RJ-11 (thats the connection on the cable that goes from the router to the filter isnt it?) cable i can get, or does distance effect it?
