I'm sorry to hear that you're experiencing difficulties with the new RLC-842A EZDriveMA camera. It's possible that there might be an issue with the camera itself or with the network settings. To troubleshoot the problem, I would recommend the following steps: 1. Double-check the network settings on the camera to ensure it is properly configured and connected to the network. 2. Restart your router and modem to refresh the network connection. 3. Try connecting the camera to a different network, if possible, to see if the issue persists. 4. Update the firmware of the camera to the latest version, as it might address any compatibility issues. 5. If the problem still persists, contact the manufacturer's support team for further assistance, as they will have more specific troubleshooting steps and can help determine if the camera needs to be replaced again. I hope this helps resolve the issue with your new camera.
