Sounds like there are a few geographical and logistical complexities going on here but does explain why you got a 'Quick Start' kit if there was a cable TV connection in the distant past.
I think you will need the VM forum team to go through these with you but might possibly include:
- abandon the idea (if your original cable has gone and been hidden under a driveway) and you want no further installation disruption
- see if a new cable can be installed to service your property in an acceptable way (but be aware some topics on here detail long delays in getting this done for some unlucky customers)
- if the cable for next door is functional then it may be possible to tap into that as a temporary measure to get you working on a shared connection (though this is rarely poplar with the customer/neighbour who becomes the cable 'donor'/sharer!)
Is your neighbour actually using the cable connection at present? If not and it is actually on your property it could maybe be used as a connection for you.
In any event, as you had already worked out, you will need a VM technician to investigate and decide what is possible.
One of the VM forum team will reply here within a day or two and will help you.
