AT&T Router Login: 192.168.1.254 and Access Code
Log in to your AT&T gateway at 192.168.1.254 using the Device Access Code. Smart Home Manager, WiFi changes, reset and fixes.
I have been locked out of my AT&T login page, and the cause is often small. People type the wrong address, or they try a password that was never set.
192.168.1.254 is the page that opens your AT&T router settings. The device access code is printed on your gateway. This guide walks you through opening it and signing in. The attwifimanager hostname opens the same page.
Open 192.168.1.254 in your browser and sign in with the device access code on your gateway.
The fastest way in: tap the login button in the box at the top of this page, then sign in with the details on your router label.
How to log in to your AT&T router
In my experience, this is the part that trips most people up.
- Connect to your AT&T WiFi or plug a cable into the gateway.
- Open http://192.168.1.254 in a browser.
- Choose the setting you want to change, such as Home Network or Firewall.
- When asked, type the Device Access Code from the gateway label and continue.
AT&T default IP address, username and password
I have seen this done wrong more than once, so I keep it simple here.
| Model or type | Login address | Username | Password |
|---|---|---|---|
| AT&T Fiber and Internet gateways | 192.168.1.254 | (not needed) | Device Access Code on label |
The Device Access Code is different from the WiFi password, although both are on the same label.
Log in with the Smart Home Manager app
I check this before I change anything else.
The Smart Home Manager app and website let you change your WiFi name and password, see connected devices and run troubleshooting without the Device Access Code.
AT&T router login not working?
I treat this as a quick check, not a deep setting.
1. Check your connection
Your device must be connected to the router’s WiFi or plugged in with a cable. Turn off mobile data on phones, because the router page cannot be reached over a cellular connection.
2. Type the address correctly
Type http://192.168.1.254 in the address bar, not the search box. Use only numbers and dots. Do not add www or .com. Our IP Address Checker fixes common typos.
3. Confirm the router IP
Your router may use a different address. Use the Router IP Finder to read the exact Default Gateway from your device.
4. Try another browser or a private window
Clear the browser cache or open a private window. Some browsers force HTTPS, so type http:// at the start.
5. Restart the router
Unplug the router for 30 seconds, plug it back in, wait two minutes and try again.
6. Turn off VPN or proxy apps
A VPN sends your traffic to another network, so your local router cannot be reached until you disconnect it.
How to change your AT&T WiFi name and password
I would rather confirm it now than fix it later.
- Log in at http://192.168.1.254 with the admin username and password.
- Open Wireless, WiFi or WLAN settings. On dual-band routers, edit both the 2.4 GHz and 5 GHz networks.
- Change the SSID to set a new WiFi name.
- Choose WPA2-PSK (AES) or WPA3 security and enter a new password. Our WiFi Password Generator creates a strong one.
- Click Save or Apply, then reconnect your devices with the new password.
How to reset a AT&T router
I always start with the router page for this.
Press and hold the Reset button with a pin for more than 10 seconds until the lights turn off and restart. The gateway returns to the WiFi name, password and access code printed on the label.
Note: a factory reset erases your WiFi name, password and other settings. Keep any internet provider login details ready before you reset.
AT&T gateway models
In my experience, this is the part that trips most people up.
AT&T has supplied several gateways, all of which open at 192.168.1.254:
- BGW320-500 and BGW320-505: current fibre gateways with built-in ONT on many installs.
- BGW210-700: very common on fibre and some DSL.
- Pace 5268AC: older gateway.
- Arris NVG589 and NVG599: older DSL and fibre gateways.
You don’t need a username. When a setting asks for the Device Access Code, type the code from the gateway’s label. Settings changes that only need viewing don’t ask for it at all.
IP Passthrough: using your own router with AT&T
I have seen this done wrong more than once, so I keep it simple here.
AT&T fibre doesn’t offer a true bridge mode, but it does have IP Passthrough, which hands your public IP to your own router. That avoids most double NAT problems.
- Connect your router’s WAN port to a LAN port on the AT&T gateway.
- Log in at 192.168.1.254 and open Firewall, then IP Passthrough.
- Set Allocation Mode to Passthrough and Passthrough Mode to DHCPS-fixed.
- Choose your router from the device list and save.
- Turn off the gateway’s WiFi so the two don’t compete.
Restart your router after setting passthrough so it picks up the public IP.
