      Stats - Please help lose broadband

      Hi all been having problems with sky since November, have gone through all the tests with sky techies no luck, switched off PPnP on router still my broadband signal drops every 10 to 15 minutes, have installed mossywells bounce, it helps to reboot, but it can be very frastrating, shouldnt have to do this. I will appreciate it a lot if someone can read my /usr/sbin/adslctl: ADSL driver and PHY status

      Re: Stats - Please help lose broadband

      Well, as I'm sure you realise, your connection speed is very low for your attenuation. On a relatively noise free line you should be connecting at the full 8meg for Mid.

      The normal reason for this shortfall is down to a noisy line. Unfortunately the stats you posted only cover a couple of minutes with next to no traffic and this isn't enough to see the error levels. However, one thing I can see is that your noise margin is high which makes me suspect that Sky have capped you at 4896kbps (presumably because they could see the errors).

      Can you be more specific about your disconnection problems?
      • How are you connected?
      • What exactly happens?
      • What lights are showing?
      • Can you log into the router?
      • What do your stats show at this time?
      • What does your log show?

      It's hard to help if you don't give much info.

      I've also deleted the duplicate post you made. Please post just once with a problem. There's no need to copy it across the forum.

      Sorry for the duplicate post! thanks for deleting it, im pretty new to this tech stuff. I need to update my info I am currently on the max package.
      The problem off being disconnected happen wether I use the ethernet or wireless. I'd be online for say 10 - 15 minutes sometimes the broadband light will just go off, sometimes it can stay on for a couple of hours max untill I lose the broadband signal. I have no problems logging onto my router the stats show this:

      System Up Time 00:03:11
      Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
      WAN PPPoA 119 156 0 58 1726 00:01:39
      LAN 10M/100M 67 0 0 55 0 00:03:09
      WLAN 11M/54M 541 561 0 1801 252 00:02:59

      ADSL Link Downstream Upstream
      Connection Speed 4896 kbps 576 kbps
      Line Attenuation 36.0 db 23.5 db
      Noise Margin 18.4 db 14.0 db

      My log shows the following info:

      Sat, 2000-01-01 00:00:32 - LCP is allowed to come up.

      I do beleive that I have been capped by sky as back in November I was getting speeds off upto 9 megs. How do I preform the test for a longer duration as I am not too sure of this? do I just use my laptop as usuall then run the test again after an hour? Once again thankyou for your promt reply and I hope the info helps.

      Could be the UPnP bug. Log into your router, go to UPnP, untick the box, click apply, reboot both the router and the PC/laptop.

      Yes - looks like you have been. With that attenuation you could expect ~14000kbps on a relatively noise free line.

      Not sure why the first LCP stalled but it connected fine on the second attempt. Could be a UPnP issue?

      Yes but reboot the router first to start a fresh set of stats. More than an hour would be better. Capped as hard as you have been, the error level should be reasonably low so the longer the period (and the more traffic passed) the better.
