Resetting your WiFi and changing the IP address for your AT&T Gateway are both accomplished with this method. You will no longer be able to sign in to your AT&T Gateway by visiting the address 172.16.0.0.

Then you may save your configurations. When prompted, enter the device code from your gateway. Then, under DHCP fixed, pick the Google Nest Wifi and save the changes.
Step 7: Make Sure That IP Address Allocated To Google Nest WiFi Is Public
To connect to the internet now that Google Nest Wifi has been designated as your primary point of access, you must change the IP address allocation on the device’s network adapter to “public.”

However, keep in mind that this setting might be altered by accident, simply make certain that it is still checked. Make a backup of your configurations.

Does Google Nest WiFi Replace AT&T Gateway Router?
Because it works as a modem, the Google Nest Wifi does not completely replace the AT&T Gateway. The Google Nest Wifi, on the other hand, will be in charge of the routing.
Also, Google WiFi is designed to work with the existing modem in your house. And now most of the Internet providers in the US give router and modem combo hence replacing it goes out of the picture unless you are getting router and modem differently from your internet provider.
It is fairly simple to set up your Google Nest Wifi with AT&T if you follow all of the directions to the letter.
While this article is designed to work with the Google Nest Wifi, it can also be used with other routers, however, the steps may alter slightly.
