If the Sync Module is not connecting to your Wi-Fi network, it is easiest to follow the troubleshooting steps below.
- Reboot your Wi-Fi router and wait for the internet connection to resume.
- Power cycle the Sync Module by unplugging power for five seconds and then plug it in.
After a minute or two, the result should be a solid blue light above a solid green light on the Sync Module.
If there is any other light pattern, it may be necessary to delete the Sync Module from your system and set it up again. Perform these steps when you are physically with the Sync Module in the location where you want to set it up.
To quickly remove a Sync Module and all associated devices, you can delete the entire system. Learn how to delete a system.
Warning
Only proceed if your system is not working as expected, or if you are making network changes such as moving to a new Wi-Fi network, or updating your network password.
