I know there is on Glory. I'm sure if you call customer care before sailing, you'll be able to ask. My husband has a wireless card he takes everywhere his laptop goes, so call ahead. Even their computers are fine. I used them on all my cruises as I have a website to maintain, and that doesn't go on vacation. I actually didn't mind using a "regular" computer
The Inspiration has it and is a sister ship of Sensation, so I would think Sensation has it too. I didn't look two years ago when we were on Sensation. Carnival can tell you. I used it on the Inspiration and loved it. Have to be quick though. As soon as it connects they start charging. It was a good was to check home email from college kids and other family members. Didn't do any net surfing though..........for me would have gotten too expensive.
