AIUI 128-bit AES on non-ancient ones. For your neighbour to eavesdrop,
they need to press their device's authenticate button when you press
yours. You can probably minimise the chances of the authentication
negotiation being picked up by plugging the devices into a filtered
power strip so that they can only see each other and not radiate into
the home wiring. We have two independent pairs running here, one on
the WAN side and one on the LAN. It looks odd as two units share the
same mains socket by using their pass-through power outlet.

How many neighbours you have depends on where you live. In Britain
you're likely to have a large number scattered randomly down the
street (sharing your phase). Here we have a pole-mount service
transformer that happens to serve just two houses and two street

When we had the pole in our garden moved, they discovered that
the whole street's needed replacing, along with the transformers,
so we were lucky and didn't have to pay them anything for the move.
We just said stick it there please.
