Please check if your WiFi signal is strong enough in the room where the Philips Avent Smart baby monitor is positioned. You can do this by downloading a speed test app in the app store. Your download and upload speed at the location of your Philips Avent Smart baby monitor should be above 2 Mbps for a stable connection. Is your WiFi connection below 2 Mbps? A WiFi repeater is a good solution to improve your WiFi signal strength.
