We have the Deco X55 mesh routers in our house. Recently, somethings been going on with our home network and we can't figure out what it is. All throughout the night and morning, we're getting emails from TP-Link Cloud saying which device on the network disconnects and connects and it's just one email and one device after another. It could be anything from my work laptop to my personal laptop to our ecobee thermostat, etc. It's been happening for almost a week now and one minute a device disconnects, the following minute it connects. When we visit website from our desktop, we also constantly get a "not secure" icon in the URL bar when visiting different websites. It says our connection is not secure but we have a network key and can't figure out why we're getting that now too.
