Windows 10 enterprise 1903 breaks the concurrent use of wired and wireless NICs RRS feed

  • Question

  • Our company regularly needs laptops to connect to our domain (internet access) and to a small workgroup (isolated from internet access). Any PC that has upgraded to 1903 has lost the ability to be connected simultaneously. Each connection does work independently.

    This issue is hardware independent as it occurs on two different manufacturers and five different models of laptop. All systems have latest drivers, firmware, and BIOS. There are no settings in their BIOS to control this. There are no wireless adapter settings for disabling wireless when wired connection is plugged in.

    We have tried the following registry settings to no avail:


    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WcmSvc\GroupPolicy fBlockNonDomain

    We need this feature back.  Have I missed a setting somewhere?

    All help is appreciated.

  • From where have you downloaded Network drivers?

    I shall suggest you to update via Windows Update.

    Enable "Configure registry policy processing” under Computer Configuration -> Policies -> Administrative templates -> System -> Group policy”

    Do not enable "Process even if GP objects not changed”. (leave unchecked)

    Restart client

  • Hello,

    This seems known issue with V1903. I believe, V1903 removed the ability to simultaneously use wired and wireless. I would recommend you to first try suggestions from S.Sengupta. In case if issue still persists, report this via Feedback hub app.
