+ Arduino Yun Wireless Config Check
+
+ Checks the wireless state of Arduino Yun by calling
+ the linux command iwconfig.
+
+ Upload this to an Arduino Yun via serial (not WiFi)
+ then open the serial monitor to see the status of
+ your Yun's WiFi connection. If it's connected to
+ a wireless network, the ESSID (name) of that network
+ and the signal strength will appear.
+
+ The circuit:
+ * Arduino Yun
+
+ created 22 May 2013
+ by Tom Igoe
+
+ This example code is in the public domain.
