1. Log in to the 5G CPE02 WEB interface and navigate to [Network → Cellular Network Settings → Check Connection];

2. Check "Enable Automatic Ping Detection";

3. Set the Ping interval (e.g., 30 seconds) and the target IP (it is recommended to fill in a public IP, such as 8.8.8.8);

4. Check "Bind Cellular Network" to ensure that Ping detection is only performed through the cellular network (to avoid occupying wired bandwidth);

5. Click "Save". When the cellular connection is interrupted, the device will automatically restart dialing to restore the connection.
