What you'll need
Posted in these interests:
Whether you’re troubleshooting or setting up a new network, factory resetting your router or modem is sometimes necessary. AT&T U-Verse users can reset their devices to factory default, as well.
Resetting your device will erase data like your WiFi name and password. Be sure you’re ready to reset the device before proceeding.
1 – Locate the factory reset button
Look for the factory reset button on your AT&T U-Verse device. The reset button is usually red in color and located on the back of the device.
2 – Hold the reset button
To initiate the factory reset, press and hold the reset button for at least 20 seconds. When you release the button, the device will begin the factory reset.
3 – Wait for the reset to complete
Allow some time for the reset to complete. After about 5 minutes, restart the AT&T U-Verse device. Your router should boot up with factory default settings.
