Missing Power tab in Device Manager

Do you have these in your device manager?






Still available in the October update as far as I can see:

 

Device Manager, Network Adaptor, No Power Management Tab

I have an Asus Zenbook with 8G and 256 SSD running Windows 10 home v1903. Often, but not always, when I open the lid the PC is no longer connected to the Internet. I then disconnect and reconnect to my network to continue.
I have searched for fixes. One fix often recommended seems to be:
Device Manager/Network Adapter/(select adapter)/Properties/Power Management tab
Then uncheck "Allow this computer to turn off device". However, I don't have the Power Management tab to allow me to proceed to the fix. I have also tried changing the Power Options for the PC from Balanced to another, to see if that change might add a Power Management tab, but noticed I don't have any other Plans to choose from. Perhaps these issues are related.
I tried to add another Power Option Plan in the event that that might help, and ended up with 2 identical Balanced Plans. And I cannot delete the 2nd.
Finally, when I compare the Network Adapters in my Asus with those in my Dell, I found the following:
Asus only has a Broadcom adapter. My Dell has a Broadcom and an Intel adapter. Is my Asus missing an Adapter that it might require.
Any help is appreciated.
