Issue Details

I have a PXIe-8861 Controller working in a PXIe chassis. One or more network adapters do not show up in Device Manager or in Network settings.

It also shows several unknown PCI devices in the Device Manager.

How can I fix this issue?

Solution

Here is a list of troubleshooting steps:

  1. Check if there is any visible physical damage on the adapter
  2. If there is visible damage, please contact NI support or your local distributor for repair. 
  3. Make sure you have Intel® Network Adapter Driver for Windows® 10 installed.
  4. Power-cycle the PXIe controller. You can do this by shutting down the controller, and then removing the AC cable from it for a few minutes. To make sure the controller is not energized. Then connect the AC cable again and turn it on. If this doesn't work, continue with the steps. 
  5. Check if the LAN adapter is disabled. Proceed with the following steps to enable it.
      1. Press Windows Key + R to open Run.
      2. Type control and click OK.
      3. In the Control Panel, go to Network and Internet > Network and Sharing Center.
      4. Click on Change Adapter Settings from the left pane.
      5. Right-click on your ethernet adapter and select Enable.

    The steps above should enable the Ethernet adapter on the controller.

    As a last step, shut down the controller and remove the CMOS battery on the PXIe controller (see more details in additional information section).

      • Leave the controller idle for a few hours.
      • Reinsert the battery.
      • Restart the controller and wait for the system to look for and recognize all the hardware components.
      • Check if the Ethernet adapter is showing in the Device Manager.

    Note: If the issue is temporarily fixed by any of these steps, but it keeps happening, contact NI Support to evaluate if the controller should be sent for repair. 

    Additional Information

    If you decide to replace the battery (BR2032 3V Battery), NI will not be responsible for any damage to the controller.  Before you replace the battery, make sure you inspect the controller to make sure that the metal clip is making contact with the battery, the battery edges are not corroded, and that there is no physical damage to the controller.

    To replace the battery yourself, follow the instructions below:

    1. Place the controller on a table, hard drive side down.
    2. With your finger nail, gently pull back the negative terminal pressing against the flat side of the battery.
    3. Using needle nose pliers remove the battery. The battery will not lift straight up. You have to tilt it slightly towards the processor then lift it out.  
    4. Using needle nose pliers, re-install the battery by pulling the negative terminal (flat side) out enough to slide the battery in at a diagonal. If you accidentally reinstall the battery backwards it will not harm the CMOS.
