I am assuming that you already have a hi-speed internet connection.
If so, find out if there is a Frye Electronics store in your local area. You can buy a wireless router there for $21.99. If not go to their website at http://www.outpost.com. It is an Airlink AR315W 54Mbps Wireless-G Cable/DSL Broadband Router (Item #: 4056592). I have one and it works great.
