Interested in updating your Pace gateway 5031NV ? Posting the process that worked for me, which hopefully helps others interested in good security hygiene of firmware updates. First step is to screenshot settings in the gateway, since AFAIK there is not a configuration backup mechanism. Record the Device Access Code (on label), and wifi password (on the other label :) ). Factory reset via settings>diagnostics. Yup. This is AT&T (via sonic support) recommendation. Access gateway, bask momentarily in the updated firmware, then get busy adding back in all the configuration.
