I understand this error means I dont have the wifi library installed, but I feel stupid after a massive search trying to find out where the wifi.h library zip file is (on internet) just so i can download it and add to my list of librarys. Is there something Im missing? thought this would have been pre installed? Sorry if Im lacking a basic something. thanks in adbance
Im using a RN VX 171 module with wireless shield, but also have an xbee shield from sparkfun.
I thought ID start with this simple wifi scanning example to get thing going.... Ultimately I want to just read an analogue sensor wirelessly and post the reading to cosm through our wifi network.
You can see the #include <wifi.h> below
/*
This example prints the Wifi shield's MAC address, and
scans for available Wifi networks using the Wifi shield.
Every ten seconds, it scans again. It doesn't actually
connect to any network, so no encryption scheme is specified.

My question is regarding why i cant see the "wifi.h" lib on my mac? i have the latest version too.
Am I missing something obvious here? When referred to the arduino.cc lib reference there is no link to specifically download this wifi.h/cpp to my mac.
