The Wi-Fi G Demo Board utilizes the EasyConfig mechanism in TCPIP WiFi EZConfig demo app, which allows configuration of an embedded device on a wireless network. It utilizes the web server of the TCP/IP stack to allow the user to input the desired network information from a client browser, and then reset the device to connect to the desired network. By default, Wi-Fi G Demo Board will start up in SoftAP network mode.
