Surface DOCK Dropping network connection

Question

Hi, I have a really frustrating issue.  We have new Surfacebooks with the Dock & two monitors.  Initially we had issues with the monitors flickering which seems to be resolved by updating the dock to the latest firmware.  One issue remains which is killing me....the dock, plugged into Ethernet keeps dropping the network connection to the NAS & Internet.  This was stable in January after installing the surfacbook:

Also, I updated the Dock by using this:

I think the latest Feb 2018 Cumulative update has caused this issue to "surface" again.  The MS engineer says I need to re-install Windows which quite frankly is not an option as the device was new 2 months ago and it will receive the Cumulative update anyway.  Any help would be appreciated.

Thank you.

Hi Howard,

You can restore your Surface Book 2 to its earlier working version to undo the changes made by February 2018 Cumulative update and to check if the issue persists. You can also submit your comments to the Feedback Hub, so our developers would be informed about the issue.

Regards.

Hi Erwin, thank you for this, however it's not really a permanent solution.  

I did lots of digging around and I found this that seemed to have worked for the moment, I do not know if the next CU will overwrite the settings:

Go to Network and sharing centre > Change adapter properties > Surface Ethernet Adapter > Properties > Configure > Advanced

Disable - Energy Efficient Ethernet

Disable - Selective suspend

I do find it difficult to understand why Microsoft have not had a permanent fix for this solution considering there are loads of people with this same issue.

We'll see how the fix goes and I will update the post

thanks, Howard

Hello Microsoft team, 

please can you advise if you have acknowledged my findings above, as these settings seem to have resolved the network drop issue.  It would be good to know that you also do not reset these settings in a CU or when the adapter driver gets upgraded?

thank you
