      Speed Dropping Overnight

      I'm having issues maintaining a stable connection and line speed during the evening, approx between 19:00 and midnight. My connection speed was manually set by CST on Sunday to 5.2 Mbps as I've previously posted but as I was watching it last night my line was dropping constantly until it eventually synched at 512 kbps down.

      I've now had my max speed set to 4 Mbps and my current stats are as below but I'm worried it'll start dropping off again this evening.

      ADSL Link Downstream Upstream
      Connection Speed 4096 kbps 416 kbps
      Line Attenuation 53.0 db 31.5 db
      Noise Margin 12.8 db 13.0 db

      What do you thing could be the cause of this and possible solution, at the moment it's become practically unusable at night.

      Have you tried a direct connection into the test socket? (see link in sig).

      No test socket. TBH I can't see it being a problem with my wiring or there'd be instability issues throughout the day. It's only been happening during the evening which seems to suggest there's something happening externally.

      Many things can affect the ADSL signal, boilers turning on, failing power supplies in various electronics but usually it is the internal wiring at fault.

      I would find the master socket, remove any extensions from it and then test from there.

      It may also be worth investing in a new type NTE5 socket with filtered faceplate (20) as this will give you the best case senario when it comes to your connection and then if the fault continues you can go from there.

      Re: Speed Dropping Overnight

      To give you some idea here are my stats from 22:50 this evening:

      ADSL Link Downstream Upstream
      Connection Speed 4096 kbps 416 kbps
      Line Attenuation 53.0 db 31.5 db
      Noise Margin 5.6 db 13.0 db

      Thankfully the connection hasn't dropped yet but you can see how much the noise margin has fallen since earlier this afternoon. It seemed to happen over the last couple of hours

      That is normal for ADSL, evening is always noisier than the mornings.

      I would still recommend fitting the NTE5 master and filtered faceplate though.

      Re: Speed Dropping Overnight

      I think it is coming back to the reason ADSL2+ would not work on your line and capped you at a very low speed. A swing of 7+dbs in your noise margin is way more than it should be, which shows there is noise problems on your line.
      You may think that your internal wiring is OK and not causing a problem, but probably about 9 out of 10 with similar problems, find that this is the case. Not having a test socket narrows your options but one thing you can try is removing the ring wire from terminal 3 on the back of your master faceplate. This alone can have a very positive effect on your connection. It is not needed with modern phones or when using filters.

      That was one of the first things I did after DLM was complete.

      It seems rebooting the router in the morning clears any errors on the line and gives me a much better noise margin again.

      ADSL Link Downstream Upstream
      Connection Speed 4096 kbps 416 kbps
      Line Attenuation 53.0 db 31.5 db
      Noise Margin 14.2 db 14.0 db

      Going on what's been happening in the last few days this should now remain constant until this evening again. If only it would remain as above, I could possibly get speeds of 6 mb or better.

      If you are of a mind, you could temporary disconnect your extensions from the Master socket and see how your noise margin holds up. If it does, it would be worth your while fitting an NTE5a socket. Until you get the fluctuating noise margin sorted, you will not get any more stable speed.
