How Do I Connect U-Verse Wireless Receiver to Nest/Google Mesh WIFi?

You cannot. The wap sets up a dedicated private WiFi network for the wireless stb’s. None of your wireless devices will see or use the other network. 

Thanks but I'm still seeing and can access my old (AT&T) wifi SSID on any of my devices.

Turn off the gateway WiFi networks. 

Hey @DiscoDave2000,

We are here to help with your Wi-Fi setup. When you originally setup your mesh network did you plug one of the mesh nodes directly into the Gateway, and disable the AT&T Gateway's Wi-Fi?

To turn off the Wi-Fi inside the gateway:

1. Open up a web browser
2. In the address bar type 192.168.1.254
3. Type in username and password
   • Username is admin
   • Password is the Access Key or A/C located on the Gateway.
4. Go to the Wi-Fi tab.
5. Disable the Wi-Fi (2.4 GHz & 5.0 GHz)
   • May need to go into advanced settings located on the bottom right.
6. Save Settings.
7. Exit.

This should give you only one Wi-Fi network (your mesh network)

Let us know if this helps.

So in this case the WAP is still connected to a LAN port on the Gateway and the wireless TV receivers are connected  if Wi-Fi inside the gateway is off?

I am asking since I have two wireless TV receivers through the WAP which is connected to a LAN Port on the Gateway and one non-wireless TV receiver connected to a LAN point on the AT&T Gateway.  I want to connect a google wi-fi mesh network which only has one LAN port. so I want to know if I leave the TV setup in place on the Gateway or buy a switch and move it to the google wi-fi?  Your input is appreciated.

Yes

Yes, leave all TV connection on or through the gateway, correct?

Thanks

Correct

Thanks
