    What to do if multiple BeneVision Medical Equipment patient monitors are disconnected intermittently?
    • C
      Christina AlexanderAug 3, 2025
      If multiple BeneVision medical equipment patient monitors are disconnecting intermittently, consider these potential causes and solutions: * Damaged APs: Ensure that the APs have been turned on and are operating properly. * Strong Interference: Use a network survey tool to check for strong interference. Remove any obvious sources of interference or adjust the WLAN deployment to meet the requirements. * Insufficient Signal Coverage: Use a network survey tool to assess the signal coverage. If coverage is insufficient in certain areas, adjust the location of the AP or add additional APs.

      If all BeneVision medical equipment patient monitors are disconnecting intermittently, the wired network may not be configured properly. Use a wired patient monitor to check the wired network configuration and ensure that the WLAN bandwidth configured on the switch is sufficient, with a 50% surplus.

      If a single BeneVision medical equipment patient monitor is disconnecting intermittently, here are a few things to check: * Coverage Area: Determine the position of disconnection and check if the Wi-Fi signal strength is greater than –65 dBm. * Patient Monitor Failure: Check if the patient monitor is easily disconnected at the same position. If this problem persists after restarting the patient monitor, return it to Mindray for repair. * IP Address Conflict: Check if the patient monitor displays a message about an IP address conflict. Also, check if an IP address is assigned to multiple devices.

    How to fix BeneVision Medical Equipment not connecting to AP?
    • C
      Charles LawsonAug 23, 2025
      If your BeneVision medical equipment patient monitor cannot connect to the AP and the Wi-Fi signal icon displays an 'X', it could be due to the following reasons: * The nearby AP is not turned on. Ensure that the AP has been turned on and belongs to the VLAN where the patient monitor is. * The patient monitor is not within the AP coverage area. Move the patient monitor to the AP coverage area and then turn it on. Make sure that the RSSI value displayed on the patient monitor is greater than -65 dBm, and that the co-channel interference complies with the requirements.

    Why BeneVision Medical Equipment patient monitor cannot connect to central monitoring system?
    • F
      Felicia PatrickOct 28, 2025
      There are several reasons why your BeneVision medical equipment patient monitor might fail to connect to the central monitoring system: * The patient monitor may not have permission to access the central monitoring system. In this case, allow the patient monitor to access the central monitoring system. * The patient monitor may not be obtaining an IP address because the IP addresses in the IP address pool on the DHCP server have been exhausted. To resolve this, connect another network device to the central monitoring system to check if an IP address can be obtained. If this doesn't work, contact your IT department. * There could be conflicting static IP addresses. Check if the patient monitor displays a message about an IP address conflict, and ensure each network device has a uniqu...
