Enable VLAN and set VLAN ID with powershell script if VLAN is not yet enabled

I'm right now trying to write a powershell script in Windows 11, that should automatically configure an usb to ethernet adapter. For this I need to automatically configure the VLAN of the adapter.

Everything works fine in case the VLAN was already activated in the network dialog using

Set-NetAdapter -Name Adapter -VlanID 999

In case the network adapter is not yet configured the script fails with:

Set-NetAdapter : Requested operation not supported on adapter

The screenshot* shows on how to disable VLAN on the adapter:

VLAN is disabled in network settings

Does anyone knows how to enable VLAN with powershell in the first place prior to setting the VLAN ID?

Solution

  • Try running the following command:

    Get-NetAdapterAdvancedProperty

    If you test with this you should be able to tell what property needs to be set e.g.

     Set-NetAdapterAdvancedProperty -DisplayName "Jumbo*" -DisplayValue "4088 Bytes"
