WiFi Shield doesn't find networks

Hi, I just started using arduino, I have UNO (Infiduino R3) and I just bought CC3000 WiFi shield.
I tried to run the sketch from ArduinoWiFiShield - "scan for available networks"

but I get no results, and my shield MAC is all zeros

Initializing Wifi...
MAC: 0:0:0:0:0:0
Scanning available networks...
** Scan Networks **
number of available networks:0

any ideas whats wrong?

That is because the CC3000 wifi shield is not compatible with the standard WiFi shield example sketches. You must use a library that is designed for the CC3000.

thank you I just downloaded the library and I can see my network now
