Are you looking for a provider or do you already have internet access?
Most, if not all major providers (Fios,, comcast,, verizon high speed,,,Etc) give you a wireless modem/router with the package. Some for as little as 19.99 per month.Installation is simple,,all come with a disk you just follow along with. BEFORE you install PLEASE read cnet's sticky about wireless. They have helped me so many times with so many issues, I've lost count. http://forums.cnet.com/5208-7589_102-0.html?forumID=62&threadID=264135&messageID=2584349&tag=forums06;posts
