Hello guy!
You can do these two steps and hope its can help u:
Clearing ONT data is similar to restoring factory settings for an ONT. Use either of the following
methods to restore factory settings for an ONT:
● Choose System Tools > Restore Default Configuration from the main menu on the web
page and click Restore Default Configuration.
● Hold down the RESET button for a long period of time (longer than 10s) to restart the ONT
with factory settings.
Thanks!
