My Nest Wifi mesh system was probably hacked. The wifi router and 2 wifi points had been working fine for over 8 months. Recently I noticed a couple of 'Unknown device' messages on my network - they were always offline so I couldn't find out anything more.
A couple of days later, I got a message on Google Home app that the wifi router had gone through a factory reset. On subsequent restarts/setup to my wifi mesh system, all three devices are behaving strangely.
1) The Wifi router on setup states that it is a 'Onhub' router
When scanning the QR scan code on the Wifi router, i get a message on Google Home - 'This is not the code you are looking for'. When using the setupcode on the router, the device resets itself as a 'Onhub'.
2) The 2 wifi points on setup state they are 'google assistants'.
Any suggestions on how to proceed with these devices.
