      Just to show you what my socket looks like, I opened up the master socket last night, and it has the test socket next to it, from what I gather it's a really old one.

      And I have also used the Mognuts utility to up my noise margin, I selected 15db and it is now at ~17-18, connected at 3.3mb as opposed to 5.5. Connection has been a lot more stable.

      Your phones have been wired using the wrong colours which means probably a diy job, But no matter just means its green pin 3 that needs disconnecting rather than orange in all sockets, hope it helps.

      What does the green one do? And if removing it messes it up, is there any way I can connect it back up?

      Re: Noise Margin and disconnection issues

      Pin 3 is a ring wire, in the old days it was required to make telephones plugged into the extension ring but modern electronic phones dont need it. The only thing it does is cause lots of noise and line errors on broadband many people find disconnecting it improves there broadband no end including ME! I went from 6 to 8 disconnections a day and dial up speeds in the evenings to a continuous 8mb perfect connection for the last 5 months just by disconnecting that one wire! My before and after stats are below you will see CRC errors dropped dramatically, and the SNR went up from 9.3 to 15.6, that was without fixing it with mognuts.

      Before:

      SNR (dB): 9.3 25.5
      Attn(dB): 34.0 17.9
      SF = 17328770
      CRC = 305932
      LOS = 3523
      LOF = 0

      After:

      SNR (dB) 15.6 26.5
      Attn(dB): 34.0 18.4
      SF = 5126897
      CRC = 18
      LOS = 3
      LOF = 0
      ES = 12

      If you're worried that you might have to re-connect the green wire, then you should buy the correct tool to do it. It's called an IDC insertion tool. You can buy a cheap disposable plastic version from Maplin (and many other places) for about 1. These are only good for two or three goes, but that's all you need. The professional version is much more expensive Here's what they look like (although they are usually white rather than brown).
