      Sudden drop in Sky Broadband Speed

      I've been on Sky Broadband for a few years now and not had any major problems till now. I moved to the unlimited service a few months back and noticed a slight drop in my Download speed and the connection has dropped speed now and again, but has been fine after switching off then on the router.

      Thursday night I started downloading a large number of iTunes Video Podcasts and easily expected to find them finished by the morning. Friday morning, I realised that it was still downloading and had failed to complete half of the podcasts. The speed had dropped off. After unplugging the router a few times I managed to get the speed up so that I could use the internet, but downloads were still struggling.

      Saturday comes and the connection almost disappears completely. I must have unplugged the router a dozen times and each time the connection comes back for a few minutes before beginning to die off again. Downloads were running at 10k - 30kb a second rather than around the 400kb I'd normally get.

      I have noticed that the connection seems to get unstable under a noise margin of 7.5 (which didn't happen before). Is there a way I can set the connection speed or noise margin level when the router is reset to see if I can get a stable connection?

      My current connection (left over from my last reset last night) is better than yesterday, but it's still not great.

      My current stats:
      ADSL Link Downstream Upstream
      Connection Speed 3783 kbps 796 kbps
      Line Attenuation 48.0 db 28.7 db
      Noise Margin 8.1 db 12.0 db

      Last Speedtest this morning:


      Have I messed my connection up by resetting too many times?

      How are you connecting the router to the PC? If by wireless try a wire, also try connecting the router to the TEST socket and post the stats from there.

      Re: Sudden drop in Sky Broadband Speed

      I should have mentioned that I have 2 laptops and 2 PS3's all wirelessly connected and they are suffer the same. I tried switching them all off and restarting everything but still get the same problem.

      As suggested, I've plugged this laptop in by cable and disconnected the wireless. It's even slower now - 10KB downloads per second. I've been lucky to be able to post this!

      I'll try the test socket this afternoon once the wife and kids have gone out - I plan to turn off everything in the house to just have the microfilter and the grey lead running to the test socket.

      It is very windy and rainy today, but the weather was okay yesterday when I had the same trouble and the line from my house to the telephone pole was replaced 2 years ago so wouldn't have thought that was the problem.

      Current Stats:
      ADSL Link Downstream Upstream
      Connection Speed 3783 kbps 796 kbps
      Line Attenuation 48.0 db 28.7 db
      Noise Margin 7.3 db 12.0 db

      Plug in via cable again and trun off the wireless in the router just to ensure it is using the ethernet and try again, use the speedtest on this site as it is more reliable.

      Sorry I'm having trouble finding the speed checker on this site...

      Please could someone post a link or let me know where it is?

      Many thanks.

      Re: Sudden drop in Sky Broadband Speed

      Ta very much!

      Things seem to be getting better now (both ethernet and wireless):

      Test taken
      (up to) Download
      Speed (Kbps) Upload
      Speed (Kbps)
      28 February, 2010 13:40:17 3728 Kbps 651 Kbps
      28 February, 2010 12:55:00 2856 Kbps 643 Kbps

      ADSL Link Downstream Upstream
      Connection Speed 3783 kbps 796 kbps
      Line Attenuation 48.5 db 28.7 db
      Noise Margin 8.4 db 11.5 db

      I think it was when my noise margin was going below 8.0 that problems were starting. I'm sure it never used to get unstable till it was below 7.0 before. Also everytime I restarted the router yesterday it came on at around 7.5 and I couldn't get it any higher.

      I don't want to mess with it anymore as it's working adequately at the moment. If it messes up again I'll do the full test socket test as I was going to this afternoon. Thanks for your help so far.

      The default is 6.9 so if you can't sync at 7 then you are probably capped, to aid the stability of the line. Most lines will go down below the default with no problems, some as low as 3 or 4, you obviously have a poor line.

      Re: Sudden drop in Sky Broadband Speed

      Okay things got bad again during the week and this afternoon I disconnected everything and reset the router again. After rebooting I got:

      System Up Time 00:02:34
      Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
      WAN PPPoA 16 14 0 23 102 00:01:06
      LAN 10M/100M 306 0 0 413 0 00:02:31
      WLAN 11M/54M 561 480 0 1143 464 00:02:24

      ADSL Link Downstream Upstream
      Connection Speed 4095 kbps 796 kbps
      Line Attenuation 48.5 db 28.7 db
      Noise Margin 7.6 db 12.5 db

      Speedcheck @ 14:50 We have detected that your ISP is Sky. Your download speed is 3568Kbps. Your upload speed is 634Kbps. This is what I have been getting for the past 3 years.

      Everything has been great for 4 hours, but thought I'd check the stats again and got this:

      System Up Time 04:09:09
      Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
      WAN PPPoA 570108 1069586 0 1972 106348 04:07:41
      LAN 10M/100M 5279 0 0 41 0 04:09:06
      WLAN 11M/54M 1078804 576993 0 106887 2611 04:08:59

      ADSL Link Downstream Upstream
      Connection Speed 4095 kbps 796 kbps
      Line Attenuation 48.5 db 28.7 db
      Noise Margin 1.9 db 12.0 db

      The noise margin seems terrible, but a speedcheck seems to show that everything is still running as it should:

      Speedcheck @ 19:03 We have detected that your ISP is Sky. Your download speed is 3528Kbps. Your upload speed is 652Kbps.

      Any ideas? Normally a noise margin that low would have reset my connection.
