I assume you just want to know if there is an internet connection (not
necessarily wifi)?  If you are using C, libconic is the place you should
be looking in:
http://maemo.org/development/documentation/how-tos/3-x/howto_connectivity_guide_bora.html#LibConIC
http://maemo.org/api_refs/3.0/connectivity/libconic/index.html


If I remember correctly it goes like this (not exactly a one-liner):

 * create object with con_ic_connection_new()
 * connect to the connection event signal
 * run con_ic_connection_connect() with parameter
   CON_IC_CONNECT_FLAG_AUTOMATICALLY_TRIGGERED
 * your signal handler will get a en event that
   has connection status.

If you want to constantly monitor changes instead of just checking once,
set automatic-connection-events to true. IIRC one of the event objects
also lets you check if the connection is a WLAN if you really are
interested in that.

HTH,
