Using Google nest mesh system with ATT fiber

What do I need to do to make this work? We have att fiber with the att BGW320 new modem/router. Have had techs come over but they don’t know how to fix.

Here are the steps to enable IP Passthrough mode on the 320.  If at some point it asks you to enter the Device Access Code you'll find that on the label on the back of of the BGW. Before you start, make sure you know the Google Wifi's MAC Address, which should be on a label and/or on the box it came in.  In Step 7 you should see that address but if not just enter it manually.

 

  1. Open a browser on a computer that is directly connected to the BGW.
  2. In the address bar, enter http://192.168.1.254.
  3. Select the Firewall tab in the BGW user interface page.
  4. Select IP Passthrough below the Firewall tab.
  5. Select the Passthrough option from the Allocation Mode drop-down menu.
  6. Select DHCPS-fixed from the Passthrough Mode drop-down.
  7. Enter the MAC address of the device that is to be set up to receive the public IP address in the Passthrough Fixed MAC Address field.
  8. Select Save. A re-starting gateway reminder message appears.
  9. Select Restart Now to complete the setting change.

     Once you've confirmed that the Google Wifi is up and running, don't forget to go back into the BGW and go to Home Network, Wifi and then click Advanced Options.  You'll want to turn WiFi Operation OFF for both the 2.4GHz and 5GHz bands to avoid conflicts.

@tonydi thank you so much. I was able to follow all the steps, however I am still seeing 0 and 0 down and upload speeds when I run speed tests on the Google home app. I think they are still getting interference. Anything else I should be doing? 
also, when you say directly connect to the gateway, I don’t have an Ethernet cable to connect my laptop to the gateway, is connecting via the wifi network sufficient? 

thank you for taking the time to try and help me!

Yes, a wifi connection to the BGW will work for the initial setup. 

I don't know why the Home app is showing that but my first inclination would be to disable wifi on the BGW and then use a computer to run a speed test.  That way you know you're connected to the Google wifi. If there's no Internet then something is set up wrong in the IP Passthrough settings.

However, because you don't have an Ethernet cable, should that test fail you don't have any way to connect back to the BGW and make changes.  Your only option at that point would be to hold done the little red reset button on the BGW for 15 seconds to put every setting back to factory.  Of course that would wipe out the IP Passthrough settings along with any other customization you've done in the BGW (SSID and/or password changes, etc).

It connects to the BGW via an Ethernet cable.

Gotcha.  The "base" or router part of the Nest wifi package needs the Ethernet cable connection, there's no way to connect it to the BGW via wifi.

Yep, that's what we all know but I don't want to assume OP knows 1 must be wired to the BGW320 (yellow) port. It is all a mystery until OP tells us exactly how they're connected.

@morph27 yes the Google nest is wired to the #1 yellow port on the BGW320. 

@tonydi we have run speed tests on a computer and the Google wifi up/down speeds are showing as good, up and running. Not quite as high as the att fiber network speeds right next to the modem but satisfactory for what we need. 
however, when I get on the Google wifi and try to run any app, it is either not connected or running extremely slow. 

I don’t think my MacBook Air even has an Ethernet port so I will just have to do the reset button if it fails.

Color me confused. 

we have run speed tests on a computer and the Google wifi up/down speeds are showing as good, up and running

So that's good.  But then you say....

when I get on the Google wifi and try to run any app, it is either not connected or running extremely slow

So the Google Wifi speeds are good but then it's not connected or really slow.

I'm going to need some clarification here.

Sorry, it is very confusing.


So we are getting conflicting speed results tests, on the att smart home management app, the Google wifi shows as connected with decent speeds. The speed test done on the Google home app shows 0 and 0. 

When I connect on my phone to the Google wifi network, everything runs extremely slow, or not at all. 

The fiber/gateway network never completely shut off though after changing both the 5 and 2.4 settings to OFF. Which is strange. I believe that is the problem

Ok, let's step back a bit and try and simplify things.

  1. First, if you can, turn the BGW's wifi back on for both 2.4GHz and 5GHz.
  2. Then power off the Google Wifi devices
  3. Using your computer and web browser, go to this address http://192.168.1.124
  4. Click the Diagnostics tab, then click the Speed Test link and then click the Run Speed Test button.  Report back with the download and upload speeds.
  5. Download the Speedtest by Ookla app from the Mac store and run it and report back the download and upload speeds given.

Some questions for you at this point.

Do you have the same Wifi Network Name (SSID) for both the 2.4GHz and 5GHz bands on the BGW?

Did you use those same SSID name(s) on the Google Wifi or did you create name(s) different from the BGW?
