My Google Nest Router connection to Att Fiber 1000 Model 5268ACFXN does not work

Yesterday, my Nest Router was connected to the Gateway and life was good.

I disconnected the nest router from the ATT modem and plugged it into a TMobile modem. I changed all kinds of settings in Google Home (following directions from T-Mobile, trying to get a static IP in order for HULU live to work.  Now when I plug the nest router back into the ATT modem, it doesn’t connect.  The light at the connection flashes red.

I did reset the network settings w/in Google Home app - no changes

I did disconnect all power from the router and the modem, but no changes

 In Google home, do I use the same network name that I am connected to from my laptop?  2 networks show available on my laptop, both with good connection. 

I appreciate any help to get me back up with this nest router.

Thanks from a non-techie user.

Let's help with getting your third party router set back up, @SimpleTom!


Thanks for letting us know which steps you've taken to troubleshoot so far.


You'll start by performing a Factory Reset on your gateway. This will help to clear any custom settings that may be preventing your equipment from connecting. You can perform the reset by following these steps: 

  • Locate the small red button & pinhole on the lower rear of the gateway
  • Depress for ~15 seconds

WARNINGThis will return all gateway settings to a default state. Any custom Wi-Fi passwords, Wi-Fi names, SSID, Static IP, and Port Forwarding rules will be lost. Settings can be restored, scroll to accepted solutions for steps to restore settings.


After that, please use our guide for configuring IP Passthrough and DMZplus to follow our steps to get set back up in DMZplus mode. The device that you would like to be placed in DMZplus must be connected directly to the gateway and configured to obtain an IP address through DHCP.

  1. Open a browser on a computer that is directly connected to the RG.
  2. In the address bar, enter
  3. In the GUI select Settings, then Firewall, and then Applications, Pinholes, and DMZ.
  4. Under Select a Computer, click the device name or IP address of the device you wish to put in DMZplus mode.
  5. Select the Allow all Applications(DMZplus mode) radio button.
  6. Select Save.

Let us know if you have any questions. We're happy to give you the answers you need.
