From the Carnival website:
Can I access the internet while on board?
For those guests who want the option of staying connected to the everyday world, we have implemented Internet Cafes fleetwide.
The Cafe is open 24-hours a day and features private workstations with the latest flat panel computer terminals. Guests will have the ability to send and receive e-mail and access Internet sites. Guests can access their home account through AOL, Hotmail, Juno or Yahoo or have the option of setting up their very own temporary account on board with our CruiseE-mail.
The computers are equipped with WordPad.
The Internet is accessed via satellite through a satellite modem and guests are able to surf the internet as if they were at home. Files can be downloaded as "read only" but cannot be saved, since a floppy disk cannot be inserted into the PC's.
The Internet connection speed is able to connect with bursts of 2.5 megs and 128 kbps upstream.
If Palm Pilots are wireless than guests can take advantage of our wireless access.
Guests may bring their own personal Laptop for use on board by using our Wireless Internet Service.
If the laptop is not equipped with a Wireless Internet Card, guests will need to rent one from the Internet Cafe.
If the laptop is running on Windows 2000, Windows ME, Windows 98 or Windows 95, software will be installed in order to run the Wireless System. This will take approximately five minutes.
If the laptop is running on Windows XP, the above software is not needed. The Wireless Internet Service is compatible with a Wireless 802.11b card, which is the industry standard.
Even with the wireless service, guest's personal Laptop must be used in close proximity of the Internet Cafe. It cannot be used in guest’s staterooms.
