Hello,
1. The default Wi-Fi name (SSID) and password of the ONT are displayed on its nameplate.

2. If the Wi-Fi password has been changed, you can log in to the ONT web page to retrieve or change the password. After logging in the web page, click the main menu, choose WLAN > 2.4G/5G Basic Network Settings. In WPA PreSharedKey , do not select Hide. You can also enter a new password and click Apply for the new password to take effect.

For more information about the Wi-Fi password, you can also visit:
