How To Reset an AT&T Modem

Router Modem Reset

Your AT&T modem is just like any other electronic device – over time, it can start to malfunction and might need a reset. This can help clear any connectivity issues, optimize your settings, and generally keep your modem running at its best.

Quick Answer

The AT&T modem can be reset the same way as other modems by either accessing the web interface or pressing the reset button if you cannot access the web interface. This will clear all the settings and restores them to their defaults.

It is always a good idea to reset your modem and internet connection from time to time. While resetting your modem typically isn’t necessary every day, it’s always worth checking if there are any issues with your connection before taking any drastic measures.

So, if you’re stuck in a pickle with your internet connection and need to reset your AT&T modem, follow the instructions below! 

Method #1: Reset an AT&T Modem Using the Web Interface

Resetting your modem using the web interface is the easiest way to go about it and can be done from any smartphone or computer connected to that modem.

Modems usually have details needed to access the web interface written on them, such as the default IP gateway and the username and password.

Here’s what you have to do.

  1. Open any web browser on a device connected to the modem you wish to reset.
  2. Type in the default IP and press Enter. The default IP address is usually or, or you might find it on the back of the modem.
  3. Enter the username and password to log in. For most cases, just leave the username field blank and type “attadmin” in the password field.
  4. Click “Settings” from the top menu and go to “Diagnostics”.
  5. Go to the “Resets” option.
  6. For a factory reset, click “Reset to Factory Default State”.

When your modem is reset, the lights on the front will turn off and turn back on. This means that the modem has been reset and is now ready to be used again.

The blinking patterns will vary depending on the model of the modem, but they generally indicate that the modem has been reset.

You can try the next option if you are having trouble accessing the web interface or find this method confusing.

Method #2: Reset an AT&T Modem Using the Reset Button

Resetting your AT&T modem using its physical reset button is an easier option when you are having trouble accessing the web interface.

Almost every router and modem has a reset button, usually on the back or bottom. All you have to do is find it and press it.

You can do this by following these steps.

  1. Power on the modem if it isn’t already.
  2. Look for a small recessed button labeled “Reset”.
  3. Push down on this button. If it isn’t sticking out, use a paperclip or toothpick to access it.
  4. Hold down for at least 9-10 seconds.
  5. The modem will now power off and then back on.

This will reset your modem to its factory settings. To indicate this, the modem will reboot, and the lights on it will again blink in a specific pattern. 


If you are experiencing issues with your AT&T modem or if it is just not performing as well as it should, following these steps may help to resolve the issue. You may need to contact a professional if this does not resolve your issue.
