Thanks once again Barbara. You are - as we used to say - 'a sharp cookie.' LOL
I downloaded the network driver from your link - it went smoothly.
Uninstalled the Audio Controller and now there are no more yellow question marks in Device Manager.
I feel like everything is working as it should.
God bless you and take care.
