AT&T gateways use 192.168.1.254, not 192.168.1.1. The Device Access Code is printed on each gateway's label.
Common AT&T gateways
AT&T supplies all-in-one gateways that combine the modem (or fiber connection), router and Wi-Fi. Models you are likely to find include the BGW210-700 and the BGW320 series on AT&T Fiber, and older units such as the Pace 5268AC and the Arris NVG589/NVG599 on legacy installs. AT&T continues to introduce newer gateways, so check the model name on the label. The sign-in method below applies to all of these.
| Credential | Where to find it | Used for |
|---|---|---|
| Device Access Code | Gateway label | Saving changes at 192.168.1.254 |
| Wi-Fi network name and password | Gateway label (until changed) | Connecting devices |
| AT&T account (user ID) | Your AT&T account | Smart Home Manager, billing |
How to log in to an AT&T gateway
1. Connect to the gateway
Use the gateway Wi-Fi or an Ethernet cable plugged into a LAN port. If you run your own router behind the gateway, the gateway page is still usually reachable at 192.168.1.254 from your network, but connecting directly avoids confusion.
2. Go to 192.168.1.254
Type 192.168.1.254 into the address bar. The gateway opens a status page with
tabs for broadband, home network, voice (if applicable), firewall and diagnostics. No login
is required to view this information.
3. Enter the Device Access Code when asked
When you open a page that changes settings, or press Save, the gateway prompts for the Device Access Code. Type it exactly as printed on the label. The code is typically a string of digits and symbols, and it is easy to confuse similar-looking characters, so check carefully if it is rejected.
4. Change what you need
Wi-Fi settings are under the home network section, while IP Passthrough and port forwarding live in the firewall section. Labels differ slightly between models and firmware versions.
Smart Home Manager
AT&T's Smart Home Manager app and website are the account-based way to manage your home Wi-Fi. Sign in with your AT&T account to:
- Change the Wi-Fi network name and password
- See connected devices and their connection quality
- Restart the gateway and run troubleshooting
- Manage AT&T Wi-Fi extenders where you have them
For a step-by-step on the Wi-Fi password specifically, see how to change your Wi-Fi password.
Using your own router with IP Passthrough
On AT&T Fiber the gateway also authenticates your connection with the AT&T network, and on many newer installs the fiber connection terminates directly in the gateway. That is why most customers cannot simply remove it. AT&T gateways do not offer a classic bridge mode; the equivalent is IP Passthrough, which hands the public IP address to your own router so it does the routing, firewall and port forwarding.
- Connect your router's WAN port to a LAN port on the AT&T gateway.
- Sign in at
192.168.1.254and open the firewall section, then IP Passthrough. - Set the allocation mode to Passthrough and select your router as the passthrough device.
- Save with the Device Access Code and restart your router.
- Optionally turn off the gateway Wi-Fi so devices only join your router.
Even in passthrough, the gateway still sits in front of your network, so check the gateway's own firewall options if a game or service has trouble with incoming connections. See also port forwarding.
Common AT&T gateway problems
192.168.1.254 will not load
Confirm you are on the AT&T network and not a mesh system with its own subnet or a VPN. Try a wired connection. See can't access router for a complete checklist.
Device Access Code rejected
Retype it slowly, checking characters such as 0 and O or 1 and l. Make sure you are using the code from the gateway you are actually connected to if you have more than one AT&T device.
Broadband light red or off
That points to a line or service issue. Check the fiber or phone-line connection, restart the gateway, and check the Smart Home Manager or AT&T outage tools before calling support.
Frequently asked questions
What is the AT&T router login?
AT&T gateways use 192.168.1.254. There is no username and no standard password. Status pages are visible to anyone on your network, and changes are protected by the Device Access Code, a code printed on the label of each gateway. When you try to save a setting, the gateway asks for it. More about this address in our 192.168.1.254 guide.
Where is the AT&T Device Access Code?
On the label of the gateway, usually on the side or bottom, alongside the serial number, the Wi-Fi network name and the Wi-Fi password. It is labeled Device Access Code (sometimes shortened to "Access Code"). It is set at the factory and stays the same after a factory reset. If the label is unreadable, AT&T support can help, or you can manage Wi-Fi through Smart Home Manager instead.
How do I set up IP Passthrough on an AT&T gateway?
AT&T Fiber gateways cannot be fully removed for most customers because the gateway handles authentication with the AT&T network. Instead, use IP Passthrough: connect your own router to a LAN port of the gateway, sign in at 192.168.1.254, open the firewall section and choose IP Passthrough. Set the allocation mode to Passthrough and select your router as the passthrough device (commonly by its MAC address), then save with the Device Access Code. Restart your router so it picks up the public IP. Turn off the gateway Wi-Fi if you only want your own router's network.
What is AT&T Smart Home Manager?
Smart Home Manager is AT&T's app and website for managing home Wi-Fi on AT&T gateways. Signed in with your AT&T account, you can change the Wi-Fi name and password, see connected devices and run troubleshooting. Advanced options like IP Passthrough, NAT/gaming rules and DHCP settings are still found on the local gateway page at 192.168.1.254.
How do I open ports on an AT&T gateway?
AT&T gateways handle port forwarding in the firewall section, where incoming traffic is mapped to a device under a NAT/gaming style page. You choose the device from a list and add an application or service definition with the ports you need, then save with the Device Access Code. If you run your own router behind IP Passthrough, set up port forwarding on your router instead. General background is in our port forwarding guide.
Does a factory reset change the Device Access Code?
No. The Device Access Code is fixed and printed on the label, so it remains valid after a reset. A factory reset does restore the Wi-Fi network name and password to the label values and erases custom settings such as IP Passthrough and port forwarding.
