I am using a work center 6027. I recently installed a new Xfinity cable modem/ router. I connected the printer via one of Ethernet ports. I t worked fine. The next day not.
I can connect via Wi-Fi. I have checked the Ethernet ports with different device.,zthey work. Lit green. The printer is yellow. I have swapped Ethernet cables. No help.
There was brief power outage. It did not affect other devices or the printer except for Ethernet connection
Please include the model of Xerox printer you are using so that people can try to help.
