Please let me know if there's anyway to turn off the Arduino Yun WiFi.
I need to do this under the Arduino IDE with windows 7 (not LINUX).
After trying all suggestions from different posts/forums.
None worked as after 5 minutes the WiFi is enabled again.
None of these suggestions worked:

Please advise which forum I can ask this on, etc.
Your advise is greatly appreciated.
