D3ADLYTuna: The socket had a big M in the top right corner. There are only two wires with smaller cores coming into this socket. It is the classic older phone jack socket in the protruding square white box.
Walking around the property the only thing I can see in terms of the ETP is a small ish black wire coming from the power pole to the house, It ends in the corner and is about 2m lower on the pole than the power wires to the property. No white boxes around the property and no obvious wiring coming up from the ground.
I will see if i can convince the landlord to install the master filter.
The terms 2 wiring or 3 wiring refer to the "smaller cores" a sheath with wires is a cable.
The white box if present would have been at the house end of the black aerial cable.
I would connect the live pair to the master and try the modem by itself in that. Double check that no other jack is working, the Master may not be the point that the outside line connects to 1st. That will show how the modem will perform without the influence of any other internal wiring. If you get an improvement then a filter and reconnecting the other jacks is next. No improvement then you have other issues.
