Is there a Wi-Fi connection on board?
'Connessione' — con-nes-SYO-ne. Double 's'; the 'zi' cluster sounds like 'ts'. Stress on the fourth syllable.
Ask at check-in or to a crew member. Wi-Fi on Italian ferries varies greatly — some modern ships have fast satellite internet, others have no connection at all.
'Connessione' means connection. 'Wi-Fi' is used as an English loanword. 'A bordo' (on board) is the location. The phrase 'c'è la connessione' (there is a connection) uses the definite article before an abstract service — more specific than 'c'è il wifi' which drops the noun.

On some ships Wi-Fi is paid by the hour or by data.
Qual è la password?

Ask once you have connected to the network.
Ho segnale telefonico a bordo?
Do I have mobile signal on board?
Check for regular data when Wi-Fi is unavailable.
Newer Italian ferry fleets (Grimaldi, GNV) have invested in satellite Wi-Fi, offering reasonable speeds at sea. However, during peak usage (evenings) the connection can be very slow. Some passengers use Italian mobile data roaming which works several miles from shore.
