Red most of the day

This is today's pattern on my Fuel Broadband connection. There have been better results in daytime, but I always get The Red latency loss at night. I am a light user currently - emails mostly so I do not think it is my usage

I also have a TalkTalk connection which runs on the same 4 core cable as the Fuel. Here is the Snapshot:

The performance is similar. These are in fine weather. If it rains it is nearly all red. I got the Fuel line hoping to solve years of problems with TalkTalk connection. Sadly both are similar

Comments welcomed!

If rain makes it worse and standard pings from a pc show the issue then both lines to the property have a seriousbproblem. Do the noise margins drop a lot when it is red zone time

Thanks Andrew - I suspected it was the line

Not sure how to find noise margins?

I do get some good days:

I have given up on TalkTalk customer service centre, however I am hopeful Fuel will be able to help. However the nice tech lady at Fuel Broad band said: "mine does that and it is Bt" and that "copper doesn't like rain". Any idea how to interest them in my problem?

Should be something like in the example at http://www.coolwebhome.co.uk/stats/routers.html#hg532
