Hi Nikki54,I had exactly a similar problem where my Nest Mini would not
connect to my wifi. I tried just about everthing several times but then
I changed my wifi security from WPA to WPA2 and the Nest Mini connected
to the wifi and worked perfectly. ...
My nest mini is doing exactly the same, connects to the home app via
bluetooth but will not connect to the wifi. Like you I have reset
everthing several times and even removed the security from wifi.
