I'm new to the arduino world. I am trying to build a board game (like a wireless arduino chess game - Wireless Arduino Powered Chess - YouTube). To do this, I need my arduino to communicate with a webserver. I am using an Arduino Uno R3 (Atmega328 - assembled), and I borrowed an Arduino WiFi Shield from my friend. I am also on OS X Mountain Lion.
When I run the code from the Arduino Startup guide page to scan the network (http://arduino.cc/en/Guide/ArduinoWiFiShield), I get this in my log
Scanning available networks...
** Scan Networks **
number of available networks:0
My understanding is the WiFi shield already has a MAC address. Why is it printing 0:0:0:0:0:0? I connected a LED pin to the WiFi shield and the shield was able to turn that on, so I know there is communication happening between the arduino Uno and the WiFi Shield. Can anyone give a suggestion on why the communication is not working properly? Also, I want to demo my project at school, but the school's WiFi network is WPA2 Enterprise. I believe that the Arduino WiFi Shield will not be able to connect to it. Should I switch to bluetooth and have my arduino Uno communicate to my laptop through bluetooth and then communicate to a local server instead? I'd like my board game to be able to stand alone.
