do you have already checked that you have direct IP connectivity? Can 
you ping the other node over the network?

If you only have two nodes, ping will work with or without OLSR, because 
you can only communicate with 1-hop neighbors without routing protocol.

If you cannot ping the other node, then you have trouble on layer-2 
(wifi) or with your interface configuration.
