I just purchased the three pack of the NestWi-Fi pro. Each unit is supposed to be capable of being either a router or a point. The first unit I set up as a router onto my network fairly easily. But when I try to add the other units as points the Google app continues to only recognize them as routers and I am unable to connect them to the mesh. The App wants to connect to their broadcasting Wi-Fi but then indicates there is no connection to the Internet.
I purchased a Pack of 3 and a Pack of 2 Nest WiFi Pro. Everything work good until i tried to hook up the 5th unit and I keeps stating I am too far from the router. I'm 3 feet from it. It says you can connect 5 nodes. Apparently not. I factory reset it and tried over and over again. All my WiFi points say Weak connection in a 3,450 sq ft one story home. I feel your pain. No online help and no phone number to call. Looks like I have one unit that's a dud.
Thanks for letting us know ― let's see what happening.
A quick question: are you selecting the home during the setup process where your main Google Nest Wifi Pro router is set up?
