Hello triangulito,
I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-821-2797 or 1-800-835-6100.
I installed the Xerox Print Utility but once I have updated to Catalina OS I can't open the app, so I can't change the WIFI configuration. When I try to open the app, the only message I get is 'Error getting information', as you can see in the screenshot.
I guess there must be another supported app that let me change the WIFI configuration, right????
