It can be frustrating to have your home devices not being able to connect to the internet. Here are some next steps to start troubleshooting:

1. Check your modem and router to make sure they are connected correctly and the power is on.
2. Check if the connection to your ISP is active, and that your modem is successfully logging in.
3. If the modem is connected to your ISP, check to make sure you have internet access.
4. Verify that any firewall you have enabled is not slowing down your connection, and allows communication to your smart home devices.
5. Ensure that you have the latest firmware installed on your router and modem.
6. Try to change some settings on your modem and router, such as switching to a different security protocol, or rebooting.
