have a look at the "typical OLSR deployments" page of our wiki (its
linked in the User FAQ)
http://www.olsr.org/mediawiki/index.php/OLSR_network_deployments

when you want to use the "loopback" to store your routable IP, you
need to add it to the list of interfaces for olsrd2:

But this doesn't make much sense with a single Wifi interface...

just set the routable address of each node to wlan0 for now and start
just with "olsrd2_static wlan0".

what is your output of "ip addr" ?

It does not look like your two OLSR instances can see each other.

Do you had a look at the "Troubleshooting" page of our wiki (also
linked in the User FAQ)?
