When trying to setup a camera I get error C390. The camera wont find my WIFI network. I use EERO and there is a strong signal. I've tried switching off 5ghz which you can do in the EERO app. I've made sure to delete the camera from the NEST app. I've reset the camera by disconnecting from the power for 15s.
