After connecting the PC, the network connection may experience intermittent disconnections and subsequent reconnections？

1) Navigate to the "Web Management – Current Status" page to check whether the device has successfully connected to the Internet via dial-up.

2) Check the "4G Settings – Connection Loss Detection" page to see if you have manually configured an IP address for connection loss detection. On your computer, open a command prompt and run the `ping` command targeting the specified IP address to verify whether the response is successful. If the ping fails or times out, it indicates a network issue; in this case, the system will automatically attempt to restore the network connection. Disabling the connection loss detection feature will not affect the system's operation.

3) After enabling link loss detection, ensure that the IP address of the host being monitored can respond normally and that the returned results are valid.
