Surface dock 2 loses wired ethernet with pro x

Question

I keep loosing the wired ethernet in the surface dock 2. It happens, e.g., when the I put the surface x in standby or sleep. The wired ethernet not only stops functioning, but disappears from device manager as well until I reboot. I have the latest windows updates, updates for the surface pro x and the dock.

Hello mr_andy,

Thanks for posting your concern here.

This could be a driver or software issue on the device. Please give these troubleshooting steps a try to isolate the issue:

• **Run Surface Diagnostic Toolkit and check for Windows Update.**Restart the Surface after installing updates.
• Run System File Checker in Windows 10.
• **Download Dock Drivers.**Go to Surface Dock 2 Drivers and Firmware, click Download then choose SurfaceDock2_SEMMforDock_Win10_17763_20.054.29469.0.msi, run and install. Restart device to apply changes.
• **Disable and enable Docking port in UEFI.**See How to get to the UEFI settings on a Surface for more details. Once you're in UEFI, go to **Devices,**disable Docking portfor at least 15 seconds and then back to enable. Click Exit and Restart device.

Please let me know how it goes. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.

Thanks, it still loses the wired ethernet. Surface Pro X doesn't have the option to disable/enable the docking port.

Hello mr_andy,

I'm sorry for the delayed response.

Devices connected to dock 2 and using ethernet cable should ensure Surface Net component in device manager is up to date; with version 10.13 or higher. Follow the following instructions to update Surface Net manually:

• Open Device Manager, Press Windows key + X and select Device Manager
• Locate Surface Net component under Network Adapters
• Select Properties > advance to Driver tab and confirm if driver is 10.13.. or higher
• If version is not 10.13 or higher version, in the same tab click Update Driver
• Then select ‘Search automatically for drivers’ and follow on-screen prompts

Hope this helps.
