A. 1. Restart your router and ensure it is functioning properly. Sometimes, a simple restart can resolve connectivity issues. 2. Ensure your phone is connected to the same WiFi network you want the app to connect to. 3. Forget the WiFi network on your phone and reconnect to it. This can refresh the connection settings. 4. Check if the app has the necessary permissions to access WiFi settings on your phone. Go to Settings > ECOVACS HOME > Permissions and ensure WiFi access is enabled. 5. If the issue persists, uninstall and reinstall the app to reset any corrupted settings.
