Turning CAT5 phone cable into Ethernet for 14 villas.

Hello Everyone,

Longtime reader - first time poster! (be gentle!)

I have a unique situation I need to research and find an answer for, so I am hitting all you experts up for some advice. We think our only option for strong internet coverage in our little estate is to use the phone lines.

The situation is:

We have just had fibre installed.

We cannot get wifi to work consistently around our estate due to location, trees, etc.

Mesh won't work due to the villas being on different electricity circuits

There are 14 villas in our little estate that all have an individual phone line.

Each individual phone line connects back to a telephone junction box (old school type)

They are a CAT5 cable, and only using 2 wires, so the Orange & Green wires are free to use

I have an Electrician that can do the work needed in each villa to make an Ethernet jack/port

My questions are;

What sort of products are there that would help me connect each phone line to the Router?

Does anyone know of an instance like this and can offer some advice?

I am not a Tech-guy but I understand the situation. I just don't know where to start looking, so any advice would be greatly received!
