      Looking at the graph I would suggest that you have a couple of issues there.

      You graph:


      The first is that your connection dropped around 1am for about an hour and a quarter.

      When it returned your pings rose from 40ms to 60ms.

      The red bit from 12pm to 4pm suggests that there is either a busy connection or a line issue. It doesn't look like a backhaul issue to me, but things get worse after 4pm to 9pm which coincides with when most exchanges get really busy.

      Just for clarity, have you done a 'quite line test'? This is easy enough to do with a corded telephone. Simply ply the corded phone into the master socket, dial '1' and list for any noise on the line. If you hear lots of crackling and/or loud hissing, then you have a line fault.

      If this is the case then it will explain why your line reset over night (DLM doing its job) and why the poor performance.

      So when the exchange is really busy, I can only suffer the high pings and slow speeds? That almost feels like reducing my quality of connection because of demand. Kind of like a weird form of throttling. I am afraid I don't have a corded phone, but when pressing 17070 and doing the test, no noise or echo found. Will see if I can have a rummage in the car boot sales and charity shops for one lol

      I posted more graphs in another thread, which might further help identify what is going on.

      Thank you. A bit of miscommunication there. I have closed the other thread.

      Ok, some housekeeping first...

      Images from the other thread:
      [img]www.thinkbroadband.com/ping/share-thumb/ac762051f41081bf58020559bc0e316d-12-01-2014.png[/img]



      Now for a bit more info:

      Sky never intentionally slow down your Sky Broadband Unlimited connection. If there is an issue with the backhaul, then everyone who has a Sky Broadband connection (ADSL and Fibre) on the same exchange will have an issue. This they can and do rectify by adding an extra line for the backhaul which is then shared between everyone. These extra lines run at something like 10Gbit. Of course Sky could add more than one line, but each needs to be arranged somehow.

      The reason why we specifically ask for a corded phone to be used is because some DECT phones introduce a little background noise and others mute it when no one is talking. For your own safety you should always have a corded phone as DECT phones do not work when there is a power cut.

      If you could borrow a corded phone from someone to do the test it would be useful. Alternatively a cheap corded phone should cost no more than around 5. You can always turn off the ringer if you decide to leave it plugged in.

      So the issue here clearly is not backhaul. My router stats would show that connection could easily handle 10MB, so why is it less than that now? It was sitting at 12.2MB all day, until 8pm fine.I will try the corded phone and let you know the results.

      Thank you.

      One additional thing has come to me for you to check, if possible, is REIN.

      ::. Kitz - REIN .::

      This might explain the strange time pattern. I am not 100% sure of this at the moment, but I won't rule it out.

      If you happen to have a portable radio which can be tuned to 612KHz you may find the potential cause more quickly.

      Christmas tree lights are a common source, but these should have been taken down by now. Other sources include any electrical device with a transformer (phones, TVs, street lights). Particularly when a bit of damp has got into the item, something sadly common in a lot of areas at the moment.

      Router Stats, after noticing no change in speed overnight, confirmed with CST that DLM was paused while investigation under way, so reset Hub, and got a jump from 8.9 MB to 12.2MB again :

      Could you check for me please that the Quality monitor is using the correct IP Address?

      I suspect that when you rebooted the router you were assigned a new IP Address and your old one is now assigned to someone else. If I am wrong, then great new there.
