Caused by conflating two concepts; network interface configured, vs user
perception of a useful network.


I disagree with Jerone.  The connection is not useless, it is ready.

Once another node joins the network, it will be accessible.  However, I
don't think the connection state should be given to the user as a claim
that they have a useful network that will carry their packets to the
internet.  That's a fundamental design issue.

It can be made to work in our case, just by assigning an IP
automatically, since Sugar can operate well on a network that does not
carry packets to the internet.

p.s. modern consumer DSL and wireless routers in Australia deal with
this issue by adding an indicator; one LED indicates connected to
provider, another LED indicates success of ping to one of a set of
predefined test IPs on the internet.
