      New Activation - Connection Dropping

      Just had my first full 24 hours with my new sky mid service and while it's been OK-ish there have still been a couple of router resets in that time. Although I have put Bounce Back on and it's taken care of things, there is still a pause while it does this.

      I already have a pre-filtered master socket which BT kindly installed when I moved from ISDN Homehighway a few years back.

      I've posted my stats below but I think they look quite good. Is this the sort of thing I have to look forward now? Hence Mosseywells utility?

      I had a similar experience when I went to BT ADSLmax last year, but that settled down after a couple of months. Is it an on-going "feature" with Sky? And should I really stop moaning for the whole 5 a month it's now costing me

      Re: New Activation - Connection Dropping

      I'm pretty much convinced now that there is a flaw in Sky's ADSL implementation which means that its ADSL connections don't track the changing line conditions very well, with particular problems at around dawk and dusk. Whenever my connection freezes up, overwhelmed by errors, a resync seems to fix the problem, without a drop in sync speed, which suggests that the capacity to support my full speed connection of 15323kbit/sec is available on the line, but the router can't seem to use it without doing a full resync. As far as I understand it, ADSL should be able to cope with these changing line characteristics.

      Unfortunately, the reboot which the Bounce utility triggers will inevitably result in a temporary loss of connectivity - there's no way round that.

      I read somewhere a comment which said, "Broadcom's ADSL chipsets track changing line characteristics very well, provided they're using the latest firmware." From that, I get the impression that the older firmware (such as is probably being used on Sky's routers) DOESN'T track very well.

      your stats look fine to me - very similar to my own!

      Have you turned off upnp in the router stats? - this is a known bug that causes the router to drop connection!

      James - I think you've posted in the wrong thread - i've been following your progress in your thread - not that I fully understand everything that you say!

      edit - maybe not then!

      ^^^^^
      I don't thinks so, the reference to Mognuts sort of gives it away.

      If you have one of the old BT ADSL filterplates, it may be to your advantage to change it to one of the new ones. The old type you have is not really 'tuned' to ADSL2. They were designed for the old 'highspeed' 512kbps connection,

      Re: New Activation - Connection Dropping

      Thanks for the tips guys, I will turn the upnp off and see if it helps.

      I will look at the faceplate if it becomes a real issue, but touch wood it's been up all day now and it will get a hammering till the early hours when the msn twins are back from college.

      Re: New Activation - Connection Dropping

      It is strange dropped again at almost exactly 7:30pm ?? Pretty much the same time as last night, and I guess it will do it again between 1 and 2 am like it did last night too.

      This is something I want to find out what it is, although I guess you all have heard all this before !!

      Re: New Activation - Connection Dropping

      The 1 am drop is well documented in the forum, it is a bug in the router. The 7.30 one is not (not yet anyway) it could be caused by some local power source switching on and interfering with the line. Have a look around your house first for a solution. Check if the CH boiler is switching on, wife using the microwave, treadmills switching on, anything that could cause a surge. If you are in an urban area is there a large shop nearby that could be switching on extractors, streetlights coming on.

      I would also advise you to remove the faceplate and plug a filter into the test socket. The old type socket you have may not be up to the job.

      Re: New Activation - Connection Dropping

      I know it's trivial but its still dropping a couple of times a day and this just bugs the life out of me, but just as a test I've plugged my old router back in for a while to see how it gets on.

      Funnily enough I also use the Netgear DG834GT but with the standard netgear firmware. When I removed it to move to sky it had been up for 250 days straight with BT Yahoo Brodband so I know it's rock solid stable and does prove the normal routers work.

      Nice thing is if I swap the password I can use Bounce Back to monitor too.

      Might just be coincedence but it's synced at the same speed but when I do a speed test I've got the best figures in 5 days of trying.

      I am not sure you can do this, Mossywell's utility was written specifically for the Sky firmware.
