I hope someone can help and please excuse my ignornace on these issues.
I have ADSL through Orange over a standard BT Line (rental is with IDNET). I've had this for years with no problems. Around a year ago the broadband started periodically dropping off an dthen reconnecting. Very quickly the speed reduced significantly. Plugging a phone directly into the socket revealed a crackling noise on the line. Orange replaced all of my equipment for me but the problem remained.
I suspected this could be because of the way the BT wire entered the flat - it basically came through under the window through a bored-out hole along with the TV aerial cable. This looked like it had all got a bit rotten and I thought the logical thing to do would be to drill through the wall and bring both wires into the flat directly, without having to bend them in the previous awkward way, which also left them more exposed to the elements. Spoke to my landlord and he had this addressed with his builders whilst they were doing some other works. Came home to a neat, tidy job last year with a new phone socket on the wall ready to use.
However not shortly after the sam eproblem occured. Having done some research it looks as though the new socket is not actually a master socket at all and I have no idea if it has been wired properly. I have uploaded two photos to try and help describe the situation better:
Pic 1 - how it's wired up
Pic 2 - all the available wires
I would like to solve this situation myself (I understand the risks in terms of not using BT) without going back to the landlord. I have read some guides online but really first of all I would like a better idea of what I'm dealing with here. can I keep teh existing socket and rewire it? Do i need to buy an NTE5 instead and wirre that up? What tools do I need for the job?
Apologies for the length of this post but I really would be so grateful for any guidance.
