Google wifi ac1200 looking for ip address

[MidwestSam]

I have a tp-link ax3000 router in between my fiber jack and the google ac1200 wifi points. Trying to add mesh setup on the tp-link but it wants the ip addresses of my google wifi ac1200 points. How can I get those?

thanks

Hello MidwestSam, 

Thanks for posting here in the Community.

You can view your Google Nest Wifi points' device information using this guide: open the Google Home app > Choose Devices > Tap the device icon > Select Settings > Check for Device information. I'd also like to let you know that you may have double NAT issues because of your current network setup. For more information about this, please visit this link. 

Let me know if you still need help. 

Cheers, 
Lovely
