Hi we too have excatly the same issue. But we do not use 802.1x authentication, so surly it should be set = OFF on the printer.
We have no authentication server nor do we use certs.
How is it best to proceed pls? The 'next steps' imply a working 802.1x setup, which we don't have.
You do need to set it to Active. Here are some more details on the steps.
