Hi

Laptops connected to USB-C docking stations are experiencing intermittent network disconnections every few minutes. The network connection drops and then reconnects automatically, impacting normal productivity. How can I disable USB Selective Suspend on the USB controllers to prevent the docking station's network adapter from entering a power-saving state and improve connection stability ?

    To disable USB selective suspend on the USB controllers in Device Manager:

    1. Open Device Manager.
    2. Expand Universal Serial Bus controllers.
    3. Find the relevant USB hub or root hub device used by the docking station.
    4. Right-click the device and select Properties.
    5. Open the Power Management tab.
    6. Clear Allow the computer to turn off this device to save power.
    7. Select OK.
    8. Repeat this for other USB Hub or USB Root Hub devices if the docking station can attach through different controllers.

    This prevents Windows from selectively suspending that USB device to save power, which can help with intermittent disconnects from USB-connected devices such as docking station network adapters.

    Important: Microsoft strongly recommends not disabling selective suspend in general because it helps conserve battery power. Use this change only as a troubleshooting step for the affected docking station connection.

    If the issue continues, also test these USB-C checks:

    • Reinsert the USB-C cable by removing it, rotating it 180 degrees, and reconnecting it.
    • In Windows, open USB settings and turn on Connection notifications so USB-C problems are reported.

    Hi

    I think when USB power management places the docking station's network adapter into a low-power state. A good troubleshooting step is to disable USB Selective Suspend so Windows keeps the USB-C dock and its Ethernet adapter fully powered.

    You can do this by opening Control Panel > Power Options > Change plan settings > Change advanced power settings. Expand USB settings, then USB selective suspend setting, and set it to Disabled for both On battery and Plugged in. Next, open Device Manager, expand Universal Serial Bus controllers, right-click each USB Root Hub and Generic USB Hub, select Properties > Power Management, and uncheck Allow the computer to turn off this device to save power. I also recommend checking the dock manufacturer's website for the latest dock firmware and network adapter drivers, as updates often address stability issues. After applying these changes, restart the device and monitor the connection to confirm whether the intermittent disconnects have been resolved.
