"wireless cards?"
I know that you can use a lap top wherever you can get a signal, like at a library, coffee shop, hotel etc. But there is something new (at least I think it is new) that allows you to use this card thing, In think the acronym is PCMCA and I think it is also referred to as Personal Direct Internet Access. There is the card that you hook into the slot on your lap to, and that allows you to get a signal so you can use the internet virtually anywhere---but there has to be a cell phone tower--that's how you get the signal..from the tower, through the card gadget, and then to your lap top. What I am finding is that you can't do this in places like Brazil because there technology is not up to speed with ours. -And I think that if your cell phone doesn't work there (or work reliably there), the "card" wouldn't allow you access to the internet either, and even if it does, you are paying roaming charges.
