Thank you for the post, and sorry to hear about the issues you're having with the STWL. Holding the control button for more than 8 seconds actually turns off the Wi-Fi on the STWL. Let's try a factory reset and do setup from scratch. Follow these instructions:
1. Unplug the power cable.
2. Press and hold the Control button while reconnecting the power cable.
3. Release the Control button when the Wi-Fi® indicator is solid amber.
