Each morning I wake up and the Google Home app notifies me that a new device has joined my network.
I've read this could be a device that's changing MAC address? Any tricks to figure out what this is?
All the devices I'm aware of are already on the network and named so I'm clueless here.
I was having the same issue. It stopped after I ensured all WiFi settings for each mobile devices (phones, tablets, & watches) were configured to NOT use a random MAC. Interrogate the advanced settings for each before having it connect again. Hope this helps.
