  1. Factory reset the device. Press the reset pinhole for 10 seconds. This clears residual configurations from the old firmware that may conflict with the new one.
  2. Reconfigure your settings. Do NOT restore from the old backup .cfg file, as that might reintroduce bugs. Manually set your Wi-Fi SSID, password, and PPPoE credentials (if required by your ISP).
  3. Check for auto-configuration. Most ISPs use TR-069 (remote management). The new firmware will automatically download your ISP's configuration within 10 minutes.

This was likely for factory testing but remains in production units. Huawei Dg8245v-10 Firmware

Firmware is low-level software embedded in the device’s hardware.
