I don't know the example programs you're talking about, but
it's a pretty good bet that the example programs won't work if
the two computers can't reach each other using IP networking.

The two Python programs won't be able to communicate with each
other unless the two computers are already set up on network(s)
that allow the routing of IP packets between the two computers.
I presume that's what the "Network Setup Wizard" did (set up IP
networking), but I don't really do windows (I especially don't
do "Wizards" if I can avoid it).
