You can use the EmotiBit button to toggle ON/OFF the WiFi module on the Feather. A short press will switch OFF WiFi. Another short press will toggle it ON.

When a short press is detected, all three EmotiBit LEDs (red, blue and yellow) light up momentarily. In addition to the LEDs, the EmotiBit also prints log messages on the serial indicating the button press detection. Check out this FAQ on more details on using the serial monitor. Also, serial monitor can be useful in debugging and sharing button press logs in the forum posts.

An example serial monitor log looks something like the following:
