It depends on whether you also plan to have it connected to the
internet via a LAN connection. If you plan to *only* use WiFi, then
you can test for an active route to the internet and respond
accordingly. Something like
ping -c1 yahoo.com && echo "connected" || echo "disconnected"
which could then be routed to say the text if you want. Or you could
do something like
ping -c1 yahoo.com && play connected.wav || play disconnected.wav
to play a sound.
If you want to be notified upon the actual connection (rather than
having an easy way to test manually), and you're using
NetworkManager, you can create a script in /etc/network/if-up.d/ that
will notify you. There should be some sample scripts in there which
you can use as a starting point.
