Printer won't connect to network after switching to Xfinity Modem

I switched my personal modem/router combo out for an Xfinity gateway and now I can not get my Epson Workforce 845 printer to connect to network. It was working perfectly yesterday with my old modem (which was not an xFinity rental).

When I go to the modem login page (10.0.0.1) it shows my printer as a connected device. But whenever I try to connect on the printer usinig either WPS or inputting the password manually setup fails.

I've tried turning off xFi advanced securiity, resetting network settings on the printer, turning off 5GHz, switching my wifi security to open. Nothing has worked. All suggestions are welcome.
