I just recently bought a google nest mini, however I cannot for the life of me figure out how to connect it to the wifi. I have tried everything to get it to connect but it just wont. It keeps telling me to "disable AP isolation" however I cannot find that anywhere in my router settings.
I guess you are using the Zyxel Videotron router. this has been discussed on some other thread on the French side of the community... and no one offered a real solution besides doing a factory reset of the router (which probably won't change anything for you).
you should contact tech support to let them know you have this problem... they might have a solution now.
