What is the AT&T BGW320 login IP?

The AT&T BGW320-500 and BGW320-505 admin panel is at 192.168.1.254. Open a browser on a device connected to the AT&T network and navigate to http://192.168.1.254.

What is the BGW320 default password?

Leave the username field blank. The password is the Device Access Code (DAC) printed on the label on the side or bottom of the BGW320 unit. Every unit has a unique code — there is no generic default password.

How do I set up IP Passthrough on the BGW320?

Log in at 192.168.1.254 → Firewall → IP Passthrough → Allocation Mode: Passthrough → Passthrough Fixed MAC Address: Manual Entry → enter your router's MAC address → Save. Your router will receive the public IP directly, eliminating double NAT.

What is the difference between BGW320-500 and BGW320-505?

The BGW320-500 uses a Nokia ONT and has 1x 2.5 Gbps WAN port. The BGW320-505 uses an Azores chipset and also supports multi-gig. Both support WiFi 6. The admin interface is identical on both models.

AT&T BGW320 Login & Setup

The BGW320-500 and BGW320-505 are AT&T's current fiber gateway, deployed for AT&T Fiber (formerly GigaPower) service. It handles ONT, router, and WiFi 6 in a single unit. Admin access is at 192.168.1.254.

Login Steps

Connect to your AT&T WiFi network or via Ethernet to one of the BGW320's LAN ports
Open a browser and go to http://192.168.1.254
On the login screen, leave the username blank
Find the Device Access Code on the sticker on the side of the BGW320 — it's typically 10 characters, mixed letters and numbers
Enter it as the password and click Login

BGW320 vs BGW320-500 vs BGW320-505

Model	WAN Port	WiFi	Chipset
BGW320-500	1x 2.5 Gbps SFP	WiFi 6 (802.11ax)	Nokia / Lantiq
BGW320-505	1x 2.5 Gbps SFP	WiFi 6 (802.11ax)	Azores

Both have 4x Gigabit LAN ports plus one 2.5 Gbps LAN port. Admin interface is identical.

Key Settings

Change WiFi name and password: Home Network → Wi-Fi → Edit. You can set separate SSIDs for 2.4 GHz and 5 GHz or combine them with Band Steering.

Port forwarding: Firewall → NAT/Gaming → Add Custom Service → enter name, protocol, and port range → assign to a device's IP.

DHCP reservations: Home Network → IP Allocation → select a connected device → Allocate. Assigns a permanent IP to that device's MAC address.

IP Passthrough — Use Your Own Router

AT&T's BGW320 cannot be put in true bridge mode — it always maintains an active management connection. IP Passthrough is the equivalent, passing the public WAN IP to a connected router:

Log in at 192.168.1.254
Firewall → IP Passthrough
Allocation Mode: Passthrough
Passthrough Fixed MAC Address: Manual Entry
Enter your router's WAN MAC address (found on its label or web interface)
Save and reboot your router — it will receive the public IP

With IP Passthrough active, all inbound traffic flows to your router. Port forwarding is then configured entirely on your router, not the BGW320. This is the recommended setup for users running their own router for VPN, advanced QoS, or better WiFi coverage.

Troubleshooting

192.168.1.254 not loading: Confirm you're connected to AT&T's network (not a guest network or different WiFi). Some browsers auto-redirect http to https — type http://192.168.1.254 explicitly.

Device Access Code not working: The code is case-sensitive. Check the label carefully — common confusions: 0 vs O, 1 vs I, 8 vs B. If the BGW320 was replaced by AT&T, the new unit has a different code on its label.

WiFi range issues: The BGW320 has decent but not exceptional range for large homes. Consider adding a WiFi extender or using IP Passthrough with a dedicated mesh system.
