AT&T gateways use 192.168.1.254. Changes ask for the Device Access Code printed on the side sticker — not your Wi-Fi password.
How to log in to the AT&T router
- Connect to your AT&T Wi-Fi (or plug in a LAN cable).
- Open a browser and go to 192.168.1.254.
- Enter the username and password below. If they fail, use the ones on the router label.
- Open the Wi-Fi / WLAN menu to change your network name and password.
AT&T default username and password
| Router / ISP | Login address | Username | Password |
|---|---|---|---|
| AT&T gateway (BGW, Pace, Arris) | 192.168.1.254 | — | Device Access Code on the label |
Credentials vary by model and installation date. The sticker on your router always wins.
Change the AT&T Wi-Fi password
After logging in: Home Network → Wi-Fi → change network name and password → Save.
Use at least 12 characters. Every device will need the new password to reconnect.
192.168.1.254 not opening? Fixes that work
- Connect to the router first. Use its Wi-Fi or a LAN cable — mobile data will never reach 192.168.1.254.
- Type it in the address bar, not the search box, and include
http://—http://192.168.1.254. Many routers have no HTTPS page. - Check for typos: only numbers and dots. The letter “l” or “o” in place of 1 or 0 will not work.
- Your router may use a different address. Check the default gateway (see above) or the label.
- Turn off VPN, proxy or “Private Relay”. They send traffic outside your home network.
- Try another browser or a private window, and clear the cache.
- Restart the router: unplug it for 30 seconds, then wait two minutes after plugging it back in.
- Still stuck? A factory reset restores the default address and password.
Still need help?
If the login page will not open or the password is refused, contact AT&T support: Smart Home Manager app. A factory reset also works, but on ISP routers it can remove your internet settings — ask your provider first.
