You can click the appropriate circle in the Mesh View, either click an
existing AP, or click a circle for Mesh 1/6/11.  NetworkManager will, by
default, look through all mesh channels first for a school server, after
which it will fall back to an AP you've previously connected to.  If
none of those are found, it will try an XO-as-Mesh-Portal on each mesh
channel, then finally fall back to Mesh Channel 1 in a peer-to-peer mesh
situation.

You should definitely see wireless access points in Mesh View though
after it's booted up.

What build # are you running, and can you report the output of, from a
root terminal, '/sbin/iwlist eth0 scan' ?
