Your computers don't need a DHCP server for their LAN connections, so
remove the router from your network. You can either:

1. Leave them configured to obtain an IP address automatically. When
they can't find a DHCP server, they'll automatically assign themselves
compatible IP addresses in the 169.254.x.x/255.255.0.0 subnet. This
will add about 1 minute to the time needed for Windows to start up.

or:

2. Assign them static IP addresses in a different subnet than your
neighbor uses. All of the broadband routers that I've seen use
192.168.x.x, so assign a completely different private subnet, like
10.0.0.x/255.0.0.0 to your computers. Don't assign a default gateway.

Some ISPs allow using multiple computers on a home network within the
subscriber's house. I don't know of any ISPs that allow sharing a
connection with the neighbors.
