Arduino Uno and wireless network

What is the best possible way to connect Uno to existing wireless network?
I'm want to send sensor data to the web server and my web service.

Using a wifi shield? There are several brands available. Arduino acts as a client and sends out HTTP or TCP requests to your server.

Can you give me some links on that shields ? or tutorial how to use a wifi shield?

There is sample code in the wifi library.

thanks :slight_smile:
