• How do I log into my Adtran router interface?

  Connect your device to the router via Ethernet or Wi-Fi. Open a web browser and navigate to http://192.168.1.1 or http://router. The default username is typically 'admin' and the password is listed on the device label or found in your setup guide.

• How do I reset my Adtran gateway to factory settings?

  Locate the Reset button on the back panel of the device. Press and hold it for 5 seconds or longer until the LEDs flash, indicating the device is restoring factory defaults.

• Where can I find firmware updates for Adtran products?

  Firmware updates and release notes are generally available within the Adtran Support Community or the official Adtran Portal. Some ISP-managed devices receive automatic updates.

• What does the blinking red power LED mean?

  On many Adtran SDG models, a pulsing red LED can indicate the system is rebooting or performing a firmware upgrade. If it remains red for an extended period, it may indicate a power fault or hardware error.
