Connecting only at night?

A few days our connection started playing up, it would only connect for around 30 seconds and it would rarely even connect. I noticed when it got dark it did connect again, I thought it was a fluke, but its done it again tonight. We noticed crackling on the phone line too today.

I rang up sky yesterday and they did a line test found nothing wrong but could see all the disconnections from the logs, he eventually wanted me to take the faceplate off as usual but I need to find a converter for the square end (rj-11?) to a rectangle end so it can fit in the test socket as it fits into a filtered faceplate now.

Is my filtered faceplate kaput? We have had trouble with disconnections when it rains too ever since we moved here, so I doubt the line coming to our house is very good quality. I just don't see how it can go for being fine, then at 1:15 about 3 days ago it stops connecting.

Its connected a lot slower now than usual (4mbps down), but at least the connection is up

Connection Speed 2324 kbps 799 kbps
Line Attenuation 57.0 dB 35.3 dB
Noise Margin 16.6 dB 12.12 dB

Any ideas?

is your telephone line noisy. Raise a service call with your phone provider stating a noise on the line problem. do not mention broadband.

Noise Margin 16.6 dB 12.12 dB

this is very high. should be around 3 or 6 rather than 16.

Phaps ur connection is nocturnal lol.

Try it in the test socket, you will need a broadband filter to do this. If it's still dropping out in the TEST socket Sky will send out an openreach engineer who will fix it.
