So I was advised to join the 21CN trial.........

[#1]

I'm going to post everything that you need to know later today but i'm holding off for a bit as i'm logging things with http://faults.plus.net too. They need 3 speedtests and I'm going to try do that too. I'll post everything later as I said and we can see where we go from there.
P.S. Extension wise I don't have anything else connected to the phone line. No sky box filter or nothing. Just my phone filter thingy.

Here's today's joyful results.  (Been on the test socket since last night with this so not touched anything) I will alter my post to show line stats with the normal socket plugged in.
