Wireless is the way for all new ships - and I believe the Carnival Freedom has wireless from stem to stern including the cabins. So no cables are needed - I'd doubt that cabins even have an ethernet plug-in. I was surprised to find fairly widespread wi-fi on the Holiday last week since it is Carnival's oldest ship. I was able to use my laptop in our suite, by the pool, and in other areas. This was a major improvement from our previous cruise on this ship when wi-fi was only in the library. As long as your laptop has a card that can handle wireless G you should be fine.
