Just like how JSH said buy a wireless router or access point they range from 25 dollars and up depending on the speed, range, and popularity. You will want to look for a wireless B or wireless G made by Linksys, D-link, Netgear, and Belkin. These for are the cheapest out there. You must remember that you must have high-speed online capabilities for you to have wireless connectivity. When setting up the router choose non-encrypted. If all of this sounds expensive or difficult go to a Starbucks or Barnes and Noble for example to update (which is not recommended right now), play online, or browse

; just look for a wifi spot and you will be good to go.
