http://192.168.1.254, any change requires the Device Access Code (DAC). This is an 8 to 12 character alphanumeric code printed directly on the white sticker on the back or bottom of your BGW320, BGW210, or NVG599 gateway tower.
How to Log In to AT&T Gateway Settings
- Connect to AT&T Network: Connect your device via Wi-Fi or Ethernet to the AT&T BGW320/BGW210.
- Navigate to 192.168.1.254: In any browser, type
http://192.168.1.254and press Enter. The AT&T Gateway status dashboard will load without prompting for a login. - Trigger the Access Code Prompt: Click on any configuration tab (e.g., Home Network → Wi-Fi or Firewall → IP Passthrough). A prompt will request the Device Access Code.
- Input the Physical Code: Carefully enter the alphanumeric string printed under Device Access Code on the gateway label. Click Continue.
Setting Up Third-Party Mesh (Eero, Nest, Orbi) on AT&T Fiber
AT&T gateways do not feature a standard "Bridge Mode" switch. To connect a personal mesh system without creating a Double NAT conflict, configure IP Passthrough:
- Log into
192.168.1.254with your Device Access Code. - Go to Firewall → IP Passthrough.
- Set Allocation Mode to
Passthrough. - Set Passthrough Mode to
DHCPS-fixed. - In the Passthrough Fixed MAC Address list, select your mesh router's MAC address.
- Go to Home Network → Wi-Fi → Advanced Options and turn off both the 2.4GHz and 5GHz Wi-Fi bands on the AT&T gateway so only your mesh system broadcasts Wi-Fi.
What happens if my AT&T Device Access Code sticker is scratched off or missing?
If the sticker is illegible and you have never changed the code, you will need to contact AT&T Technical Support (1-800-288-2020) for gateway replacement or check if a previous technician recorded the DAC on your original installation work order.
Can I change the AT&T Device Access Code to a custom password?
Yes. Once logged into 192.168.1.254 using the factory DAC, go to System Information → Device Access Code. You can enter the current DAC and specify a new custom administrator password.
Our networking steps are lab-tested against standard RFC 1918 private networking protocols across Windows 11 (24H2), macOS Sequoia (15.1), iOS 18, and Android 15. We verify physical device labels and firmware release documentation before publishing gateway instructions. Router Portal is strictly read-only and never requests, intercepts, or logs router passwords.
