Hi there and welcome
Do you mean you receive a new router at your location?
If so, then you need to connect the printer to the new router as it is not on the new network
To do this
Press Settings on the control panel.Press the Up or Down arrow key to choose Network, and then press OK.Press the Up or Down arrow key to choose WLAN, and then press OK.Press the Up or Down arrow key to choose Setup Wizard, and then press OK.When Enable WLAN? appear, press OK.
Follow the steps to connect it to your new wireless network
Once done, then try to print to it
Let me know the results please.
