Hi Rhapsody,
Most laptops come with a wireless adapter, so you can use wireless internet rather than a landline (highspeed, modem etc). Basically just ask when you're buying if you need to buy anything else for your laptop in order for it to be able to utilize a wireless internet signal. Actually wireless internet will only work if you're in an area with lots of traffic (internet traffic) that has people actually using a wireless box. But technically you should look into getting your own wireless connection.
I'll check out the link above as soon as I post this.
