Tried that as well. The two devices are seeing one another and, it seems, connecting, but every time before I can enter the password to connect the CC to the wifi, google home stops working.
Recently moved from Telkom ADSL to Vodacom fibre necessitating change of WiFi address. Get as far as entering the new address but, before I can enter the password, I get the error message "Unfortunately Google Home has stopped". Any suggestions?
