Steps to troubleshoot connection issues:
1. Move your Sense-U device close to your WiFi router and make sure you are able to connect to internet.
2. Verify the WiFi password has not been changed recently.
3. Switch your smartphone to cellular plan to see if it is able to stream the video.
4. Check your network connection and WiFi password.
5. Replace the power cable and plug it directly into an independent wall outlet.
