Can you get specific about what you want to do? Do you already have Internet access through a wireless router at your location? Do you have cable/DSL access through the hard-wired network, and you want to be able to access that with your wireless? There are permutations inherent in your question that make it impossible to answer until you get more specific about what you already have.
