I have read a lot and I found out that the issue is the Noise Margin - in the evening, its usually at 2-5 (downstream only tho, upstream seems to be stable on 8-9db at any time)and then disconnects happen. I have tried everything: rebooting my router for over a hour to get stable 7db+ but it didnt work - couldnt get anything above 5. What else is there to do?
EDIT:
I have looked up this guide:

It seems pretty obvious what do I need to do, but I have checked my socket and cables and I have found out that there is something else before the actual master socket:
What is it? And why theres only 2 wires going from that point to master socket? (blue and white)
