657 +When the computer has completed the above fallback IP configuration,the LG01v2 Web UI is still not accessible via fallback IP.

660 +**1.Check whether the configuration is correct**
661 +
662 +Run the CMD command to ipconfig and ping 172.31.255.254.
663 +
664 +If this fails, the user needs to reconfigure.
