Development Tools IDE 1.x

Hi pros:
I am a new learner, I was trying to learn how to use the erthernet shield. I don't know how to code by myself yet, so I use the example codes involved.(Like the webServer,ChatClient and something like this.
I put the arduino and the shield together, then connect the arduino with my computer. Then I upload the done code(for example, webClient.Of course, I have changed the data like mac address,ip etc.).
But nothing happened. Why?
My house is wireless network, So I never use a cable.

Where is the problem? Why nothing happened? Do I have to do something else to run the code?

Hope for your helps , thank you !

Well, you have to connect an ethernet cable between an ethernet router on your network and the ethernet connector on the ethernet shield.

Thax for your reply. As the project I want to do is wireless, can I accomplish it with no cable? I mean, does the ethernet shield have to connect to the network with a cable? It can't be wireless?
