I have 3 Nest Protects (2 upstairs &1 downstairs).
All have been working fine for years until one of the upstairs protect disconnected from the WiFi and won't reconnect.
I've tried resetting the router and done a factory reset of the protect, removed from Home app and it just won't connect to the wifi and get error code P006.(3.10)
The 2.4 and 5 bands on the router have same names.
Very odd that it was working fine for years and now isn't. Especially as the other 2 protects are connected and working along with a nest thermostat.
Any help would be appreciated.
