OK I restarted and it's saying W3 internet connection. But it worked
fine before. And it is seeing my networks just not connecting now. And
also it's gone dark entirely and takes a while for me to see the dial.
Something is clearly wrong.
I am having the exact same issue. I have 3 that work and 1 will not
connect to same WIFI system (and was working fine for 5 months). How can
I get a replacement? Apple says I'm outside the return window and
impossible to get a person at Nest Google. ...
