Reset to Defaults
By restoring the factory settings, the router will clear all user profiles and restore the factory settings.
If the router has a USB interface, you can follow below steps to restore the factory settings by a USB drive.
1) Prepare a USB flash drive and format the USB flash drive into the fat format. Then put an empty file named reset_factory.txt in the root directory of the USB flash drive.
2) When the router is in the running status, insert the USB flash drive, and after 1 minute, unplug the USB flash drive to restore the factory state. After the factory is restored, the router will restart automatically.
Note:
If the system itself crashes, it cannot be restored from the factory via the USB flash drive.
