Do you have Google Wifi points only, or are you trying to add it to a network with a Nest Wifi router? What happens when you try to add the point?
Try these steps:
Thank you very much for your help.
I have connected the Google Wifi parent to the Internet and it works. I have a problem connecting the other two google wifi points to the wifi network. My Google Home app doesn't see them. So our wifi network is based only on 1 point.
I tried everything you are suggesting, except a factory reset.
I did it directly on the Google Wifi equipment but it did not do anything. I am reluctant to do a reset on the 3 equipment in case it would work at all.
Can I do a reset on 1 equipement at a time connecting it via an Ethernet cable to the modem ?
Thank you again
